What are the main components in OOP?</h1><p style="text-align: left;"><span style="font-size: medium;">Object-Oriented Programming (OOP) has four main components:</span></p><p style="text-align: left;"><span style="font-size: medium;">1. Encapsulation: It is the bundling of data and the methods that operate on that data into a single unit or class.</span></p><p style="text-align: left;"><span style="font-size: medium;">2. InheritanceIt allows a class (subclass/derived class) to inherit properties and behaviors from another class (base class/par ent class).</span></p><p style="text-align: left;"><span style="font-size: medium;">3. Polymorphism:It allows objects of different types to be treated as objects of a common type, often achieved through method overloading and method overriding.</span></p><p style="text-align: left;"><span style="font-size: medium;">4. Abstraction: It is the concept of hiding the complex reality while exposing only the essential parts.</span></p><h1 style="text-align: left;">2. What is the usage of inheritance?</h1><p><span style="font-size: medium;">Inheritance allows a class to inherit properties and behaviors from another class. It promotes code reusability, as common attributes and methods can be defined in a base class and reused in derived classes. It helps in creating a hierarchy of classes, making the code more organized and maintainable.</span></p><h1 style="text-align: left;">3. What is the constructor, and what are the types of constructor?</h1><p><span style="font-size: medium;">A constructor is a special method in a class that is called when an object of that class is instantiated. It is used to initialize the object's state.</span></p><p><span style="font-size: medium;">Types of constructors:</span></p><p><span style="font-size: medium;">1. Default Constructor: Takes no parameters.</span></p><p><span style="font-size: medium;">2. Parameterized Constructor: Accepts parameters to initialize the object.</span></p><p><span style="font-size: medium;">3. Copy Constructor:Constructs a new object by copying the properties of an existing object.</span></p><p><span style="font-size: medium;">4. Static Constructor: Initializes static members of a class. It is called only once when the class is first accessed.</span></p><h1 style="text-align: left;">4. What is the use of a private constructor with an example, and why do we use it?</h1><p><span style="font-size: medium;">A private constructor is used to prevent the instantiation of a class. It is often employed in scenarios like creating a class with only static members, or as part of a design pattern such as a Singleton pattern.</span></p><p><span style="font-size: medium;">Example:</span></p><p><span style="font-size: medium;">public class Singleton</span></p><p><span style="font-size: medium;">{</span></p><p><span style="font-size: medium;"> private static Singleton instance;</span></p><p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: medium;"> private Singleton() // Private constructor</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> // Initialization code</span></p><p><span style="font-size: medium;"> }</span></p><p><br /></p><p> <span style="font-size: medium;">public static Singleton Instance</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> get</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> if (instance == null)</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> instance = new Singleton();</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;"> return instance;</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;">}</span></p><h1 style="text-align: left;">5. What is encapsulation in OOP with an example?</h1><p><span style="font-size: medium;">Encapsulation is the bundling of data and methods that operate on that data into a single unit (class). It helps in hiding the internal details of an object and only exposing what is necessary</span></p><p><span style="font-size: medium;">Example:</span></p><p><span style="font-size: medium;">public class Car</span></p><p><span style="font-size: medium;">{</span></p><p><span style="font-size: medium;"> private string model;</span></p><p><span style="font-size: medium;"> private int year;</span></p><p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: medium;"> public void SetModel(string modelName)</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> model = modelName;</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: medium;"> public string GetModel()</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> return model;</span></p><p><span style="font-size: medium;"> }</span></p><p><br /></p><p> public void SetYear(int carYear)</p><p> {</p><p> if (carYear > 0)</p><p> {</p><p> year = carYear;</p><p> }</p><p> }</p><p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: medium;"> public int GetYear()</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> return year;</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;">}</span></p><h1 style="text-align: left;">6. What is the difference between abstract and interface?</h1><p><span style="font-size: medium;">Abstract Class:</span></p><p><span style="font-size: medium;"> - Can have both abstract and non-abstract methods.</span></p><p><span style="font-size: medium;"> - Can have fields (variables).</span></p><p><span style="font-size: medium;"> - Supports constructor.</span></p><p><span style="font-size: medium;"> - Can have access modifiers for methods (public, private, protected, etc.).</span></p><p><span style="font-size: medium;"> - A class can inherit from only one abstract class.</span></p><p><span style="font-size: medium;">Interface:</span></p><p><span style="font-size: medium;"> - Can only have abstract methods (methods without implementation).</span></p><p><span style="font-size: medium;"> - Cannot have fields (variables).</span></p><p><span style="font-size: medium;"> - No constructor.</span></p><p><span style="font-size: medium;"> - All methods are public by default.</span></p><p><span style="font-size: medium;"> - A class can implement multiple interfaces.</span></p><h1 style="text-align: left;"> 7. What is an object in OOP?</h1><p><span style="font-size: medium;">An object is an instance of a class. It is a self-contained unit that consists of both data (attributes) and methods (functions). Objects are created from classes and represent real-world entities.</span></p><h1 style="text-align: left;"> 8. What are the access modifiers in C#?</h1><p><span style="font-size: medium;">C# has several access modifiers:</span></p><p><span style="font-size: medium;">- Public:Accessible from any other class or assembly.</span></p><p><span style="font-size: medium;">- Private: Accessible only within the same class.</span></p><p><span style="font-size: medium;">- Protected:Accessible within the same class or a derived class.</span></p><p><span style="font-size: medium;">- Internal: Accessible within the same assembly.</span></p><p><span style="font-size: medium;">- Protected Internal: Accessible within the same assembly or a derived class.</span></p><h1 style="text-align: left;"> 9. What is the difference between the continue and break statement in C#?</h1><p><span style="font-size: medium;">- Continue Statement: Skips the rest of the loop body and proceeds to the next iteration.</span></p><p><span style="font-size: medium;">- Break Statement: Exits the loop or switch statement and continues with the next statement outside the loop or switch.</span></p><h1 style="text-align: left;"> 10. What is enumeration in C#?</h1><p><span style="font-size: medium;">Enumeration (enum) in C# is a value type that represents a set of named constants. It provides more meaningful names to numeric values, improving code readability.</span></p><p><span style="font-size: medium;">Example:</span></p><p><span style="font-size: medium;">public enum Days</span></p><p><span style="font-size: medium;">{</span></p><p><span style="font-size: medium;"> Sunday,</span></p><p><span style="font-size: medium;"> Monday,</span></p><p><span style="font-size: medium;"> Tuesday,</span></p><p><span style="font-size: medium;"> // ...</span></p><p><span style="font-size: medium;">}</span></p><h1 style="text-align: left;">11. What is an extension method, and why do we use it?</h1><p><span style="font-size: medium;">An extension method in C# allows you to add new methods to existing types without modifying them. It is a syntactic sugar that improves code readability and reusability.</span></p><p><span style="font-size: medium;">Example:</span></p><p><span style="font-size: medium;">public static class StringExtensions</span></p><p><span style="font-size: medium;">{</span></p><p><span style="font-size: medium;"> public static bool IsNullOrEmpty(this string str)</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> return string.IsNullOrEmpty(str);</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;">}</span></p><h1 style="text-align: left;">12. Difference between `ref` and `out` in C#?</h1><p><span style="font-size: medium;">- ref`: Used to pass a variable by reference. The variable must be initialized before passing it to the method.</span></p><p><span style="font-size: medium;">- `out`:Similar to `ref` but does not require the variable to be initialized before passing. The method must assign a value to the `out` parameter before it completes.</span></p><h1 style="text-align: left;">13. Can we use multiple catch blocks in a single try?</h1><p><span style="font-size: medium;">Yes, a single try block can have multiple catch blocks to handle different types of exceptions.</span></p><h1 style="text-align: left;"> 14. What is the difference between `const` and `readonly`?</h1><p><span style="font-size: medium;">- const:Value is constant and must be assigned at compile time. It is implicitly static and cannot be modified after declaration.</span></p><p><span style="font-size: medium;">- readonly:Value is constant but can be assigned at runtime (in the constructor). It can have different values in different instances of the class.</span></p><h1 style="text-align: left;">15. What is boxing and unboxing in C#?</h1><p><span style="font-size: medium;">- Boxing: Converting a value type to the object type (boxing), usually when assigning a value type to a variable of type `object`.</span></p><p><span style="font-size: medium;">- Unboxing: Converting an object type to a value type (unboxing), usually when extracting a value type from a variable of type `object`.</span></p><h1 style="text-align: left;">16. What is implicit and explicit?</h1><p><span style="font-size: medium;">It seems like there might be a typo or missing context in the question. If you meant something specific, please provide more details.</span></p><h1 style="text-align: left;">17. What is the use of the `using` statement?</h1><p><span style="font-size: medium;">The `using` statement in C# is used for resource management, especially when working with objects that implement the `IDisposable` interface. It ensures that the `Dispose` method of an object is called when the object is no longer needed, helping to release resources.</span></p><p><span style="font-size: medium;">Example:</span></p><p><span style="font-size: medium;">using (var fileStream = new FileStream("example.txt", FileMode.Open))</span></p><p><span style="font-size: medium;">{</span></p><p><span style="font-size: medium;"> // Use the fileStream here</span></p><p><span style="font-size: medium;">} // Dispose method is automatically called here</span></p><p><br /></p><h1 style="text-align: left;">18. What is the difference between `string` and `StringBuilder`?</h1><p><span style="font-size: medium;">- `string`: Immutable (cannot be changed after creation). Concatenation creates a new string.</span></p><p><span style="font-size: medium;">- `StringBuilder`:Mutable (can be changed after creation). Efficient for dynamic string manipulations due to in-place modification.</span></p><h1 style="text-align: left;">19. When will we use `string`, and when will we use `StringBuilder`?</h1><p><span style="font-size: medium;">- Use `string` when the value is not expected to change frequently, as it is immutable.</span></p><p><span style="font-size: medium;">- Use `StringBuilder` when there are frequent modifications to the string, like concatenations in a loop, to avoid unnecessary string object creations.</span></p><h1 style="text-align: left;">20. What is the conditional operator in C#?</h1><p><span style="font-size: medium;">The conditional operator (`? :`) is a shorthand way to write an `if-else` statement. It returns one of two values based on the evaluation of a boolean expression.</span></p><p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: medium;">Example:</span></p><p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: medium;">int result = (a > b) ? a : b;</span></p><h1 style="text-align: left;">21. What is `DataAdapter` in ADO.NET?</h1><p><span style="font-size: medium;">`DataAdapter` in ADO.NET is a bridge between a dataset and a data source. It performs operations like filling a `DataSet` with data from a data source and updating a data source with changes made in the `DataSet`.</span></p><h1 style="text-align: left;">22. What is the difference between `DataSet` and `DataTable`?</h1><p><span style="font-size: medium;">- `DataSet`: A collection of one or more `DataTable` objects, relationships, and constraints.</span></p><p><span style="font-size: medium;">- DataTable`: Represents one table of in-memory data.</span></p><p><br /></p><h1 style="text-align: left;">23. What is object pooling in ADO.NET?</h1><p><span style="font-size: medium;">Object pooling in ADO.NET involves reusing database connection objects instead of creating a new one for each request. It improves performance by reducing the overhead of creating and destroying connections.</span></p><h1 style="text-align: left;">24. What is the difference between `ExecuteScalar` and `ExecuteNonQuery`?</h1><p><span style="font-size: medium;">- ExecuteScalar: Returns the first column of the first row as an object. Used for queries that return a single value (e.g., SELECT COUNT(*) FROM Table).</span></p><p><span style="font-size: medium;">- ExecuteNonQuery: Used for executing commands that don't return data, such as INSERT, UPDATE, DELETE.</span></p><p><br /></p><h1 style="text-align: left;">25. What are the objects/components in ADO.NET?</h1><p><span style="font-size: medium;">Key objects/components in ADO.NET include `Connection`, `Command`, `DataAdapter`, `DataReader`, `DataSet`, `DataTable`, and `Parameter`.</span></p><h1 style="text-align: left;"> 26. What is `SqlCommand` in ADO.NET with syntax?</h1><p><span style="font-size: medium;">`SqlCommand` is used to execute SQL commands against a database. Syntax for a simple SELECT query:</span></p><p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: medium;">using (SqlConnection connection = new SqlConnection(connectionString))</span></p><p><span style="font-size: medium;">{</span></p><p><span style="font-size: medium;"> connection.Open();</span></p><p><span style="font-size: medium;"> using (SqlCommand command = new SqlCommand("SELECT * FROM TableName", connection))</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> using (SqlDataReader reader = command.ExecuteReader())</span></p><p><span style="font-size: medium;"> {</span></p><p><span style="font-size: medium;"> // Read data here</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;"> }</span></p><p><span style="font-size: medium;">}</span></p><p><br /></p><h1 style="text-align: left;"> 27. What is connected and disconnected architecture in ADO.NET?</h1><p><span style="font-size: medium;">- Connected Architecture:Maintains a continuous connection to the database while interacting with it. Uses `DataReader` for reading data directly from the database.</span></p><p><span style="font-size: medium;"> </span></p><p><span style="font-size: medium;">- Disconnected Architecture: Connects to the database, retrieves data into a `DataSet`, and then disconnects. The data is manipulated in-memory, and changes are later propagated back to the database.</span></p><h1 style="text-align: left;">28. What is connection pooling?</h1><p><span style="font-size: medium;">Connection pooling is a mechanism that enables reusing database connections instead of creating new ones for each request. It helps improve performance by reducing the overhead of establishing and closing connections.</span></p><p><br /></p><h1 style="text-align: left;">29. What is a database?</h1><p><span style="font-size: medium;">A database is a structured collection of data organized for efficient retrieval, storage, and management. It typically includes tables, relationships, and constraints to ensure data integrity.</span></p><p><br /></p><h1 style="text-align: left;">30. What is the difference between a primary key and a unique key?</h1><p><span style="font-size: medium;">- Primary Key: Ensures that each record in a table is unique and not null. It is used to identify a record uniquely in a table.</span></p><p><span style="font-size: medium;">- Unique Key:Ensures that each value in a column is unique. Unlike a primary key, a unique key can contain null values (except in SQL Server).</span></p><h1 style="text-align: left;">31. What is a foreign key?</h1><p><span style="font-size: medium;">A foreign key is a field in a database table that is a primary key in another table. It establishes a link between the two tables, enforcing referential integrity.</span></p><h1 style="text-align: left;">32. What are the joins we have in SQL?</h1><p>Common SQL joins include:</p><p>- INNER JOIN: Returns rows where there is a match in both tables.</p><p>- LEFT (OUTER) JOIN: Returns all rows from the left table and matching rows from the right table.</p><p>- RIGHT (OUTER) JOIN: Returns all rows from the right table and matching rows from the left table.</p><p>- FULL (OUTER) JOIN: Returns all rows when there is a match in either table.</p><h1 style="text-align: left;">33. How does a left join work?</h1><p><span style="font-size: medium;">A left join returns all rows from the left table and the matching rows from the right table. If there is no match, NULL values are returned for columns from the right table.</span></p><h1 style="text-align: left;">34. What is an index, and what is its usage?</h1><p><span style="font-size: medium;">An index in a database is a data structure that improves the speed of data retrieval operations on a database table. It works by creating an ordered representation of the indexed data, allowing the database engine to find rows more quickly.</span></p><h1 style="text-align: left;"> 35. What are constraints in SQL?</h1><p>Constraints in SQL are rules applied to a column or a set of columns to enforce data integrity within a database. Common constraints include PRIMARY KEY, FOREIGN KEY, UNIQUE, NOT NULL, CHECK, etc.</p><h1 style="text-align: left;">36. What is a default constraint?</h1><p><span style="font-size: medium;">A default constraint in SQL specifies a default value for a column. If a value is not explicitly provided for the column during an INSERT operation, the default value is used.</span></p><p><br /></p><h1 style="text-align: left;">37. What is a cursor in SQL?</h1><p><span style="font-size: medium;">A cursor in SQL is a database object used to traverse the result set of a query. It provides a mechanism to iterate over each row in the result set.</span></p><h1 style="text-align: left;">38. What is an alias keyword, and why do we use it?</h1><p><span style="font-size: medium;">In SQL, an alias is a temporary name assigned to a table or a column for the duration of a query. It is used to make column or table names more readable or to provide a shorter name</span></p><p><span style="font-size: medium;">Example</span></p><p><span style="font-size: medium;">SELECT employee_id AS empID, employee_name AS empName FROM employees;</span></p><h1 style="text-align: left;">39. What are the different types of functions in SQL?</h1><p>Different types of functions in SQL include:</p><p>- Aggregate Functions: Perform calculations on a set of values and return a single value (e.g., COUNT, SUM, AVG).</p><p>- Scalar Functions:Return a single value based on input values (e.g., CONCAT, UPPER).</p><p>- Window Functions: Perform calculations across a set of table rows related to the current row.</p>Suthahar Jegatheesanhttp://www.blogger.com/profile/14709587036173890626noreply@blogger.com0tag:blogger.com,1999:blog-5602264950125608941.post-26792217153601897282023-11-21T06:16:00.000-08:002023-11-21T06:16:19.767-08:00Basic information and short cut keys about visual studio<p style="text-align: justify;"><span style="font-size: medium;"> </span></p><ol style="--tw-border-spacing-x: 0;

It encapsulates the data that should be sent back to the client as a response. The action result can be a view, a file, a redirect, or any other type of data that needs to be returned.</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you specify different routing for different action methods in ASP.NET MVC?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">You can specify different routing for different action methods in ASP.NET MVC by using the `Route` attribute.

It typically includes elements such as the HTML structure, header, footer, navigation, and other components that remain consistent across multiple pages. Views can specify a Layout to inherit from, allowing them to provide content within the defined structure.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How do you define a Layout in a Razor View?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">To define a Layout in a Razor View, you can use the `@layout` directive at the top of the View file. For example:</span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b> @{</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b> Layout = "_Layout";</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b> }</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the purpose of the `_ViewStart.cshtml` file in a .NET Core project?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The `_ViewStart.cshtml` file is used to specify the default Layout for all Views in a .NET Core project. By setting the Layout in this file, you can avoid repeating the `@layout` directive in every individual View. It helps in maintaining consistency across the application.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the `ActionLink` method in .NET Core?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The `ActionLink` method is a built-in HTML helper in .NET Core that generates an HTML anchor tag (`<a>`) for a specified action method in a controller. It simplifies the creation of hyperlinks to other pages within the application.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How do you use the `ActionLink` method in a Razor View?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">To use the `ActionLink` method in a Razor View, you can call it with the desired link text and route parameters. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><b> @Html.ActionLink("Home", "Index", "Home")</b></span></p><p style="text-align: justify;"><span style="font-size: large;">This will generate an HTML anchor tag with the link text "Home" and the URL pointing to the "Index" action method in the "Home" controller.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you provide an example of how to use the `ActionLink` method with route parameters?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Here's an example of using the `ActionLink` method with route parameters:</span></p><p style="text-align: justify;"><span style="font-size: large;"><b> @Html.ActionLink("Details", "Details", "Product", new { id = 123 }, null)</b></span></p><p style="text-align: justify;"><span style="font-size: large;">This will generate an HTML anchor tag with the link text "Details" and the URL pointing to the "Details" action method in the "Product" controller, passing the route parameter `id` with the value of 123.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the purpose of the `null` parameter in the `ActionLink` method?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The `null` parameter in the `ActionLink` method represents the HTML attributes for the anchor tag. It allows you to specify additional attributes like CSS classes, styles, or data attributes for the generated link. By passing `null`, you indicate that no additional attributes are required.</span></p><p style="text-align: justify;"><br /></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the difference between a Layout and a Partial View in .NET Core?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">A Layout is a shared template that defines the common structure and design of multiple web pages in an application. It typically includes the HTML structure, header, footer, and other common elements. On the other hand, a Partial View is a reusable component that represents a portion of a web page and can be included in multiple views. Partial Views are typically used to encapsulate and reuse specific sections of the user interface.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you pass HTML attributes to the `ActionLink` method in .NET Core?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">To pass HTML attributes to the `ActionLink` method, you can use an anonymous object to define the attributes and their values. For example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>@Html.ActionLink("About", "About", "Home", null, new { @class = "nav-link", id = "about-link" })</b></span></p><p style="text-align: justify;"><span style="font-size: large;">In this example, the `@class` and `id` attributes are added to the anchor tag generated by the `ActionLink` method.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you customize the generated URL in the `ActionLink` method?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">Yes, you can customize the generated URL in the `ActionLink` method by using the `routeValues` parameter. The `routeValues` parameter is an object that represents the route parameters for the target action method. You can provide values for these parameters to construct the desired URL. For example:</span></p><p style="text-align: justify;"><b><span style="font-size: medium;"> </span><span style="font-size: large;"> @Html.ActionLink("Edit", "Edit", "Product", new { id = Model.Id }, null)</span></b></p><p style="text-align: justify;"><span style="font-size: medium;"> </span><span style="font-size: large;">In this example, the `id` parameter is passed to the `Edit` action method in the `Product` controller, allowing you to generate a URL with a specific ID.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you style a `ActionLink` differently based on the current page or active state?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">To style an `ActionLink` differently based on the current page or active state, you can add CSS classes or apply inline styles based on certain conditions. You can use conditional statements in your Razor View to check if the current page matches the target page and apply the appropriate styling. Alternatively, you can use JavaScript or jQuery to modify the CSS classes or styles dynamically based on the active state.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you generate a `mailto:` link using the `ActionLink` method in .NET Core?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, you can generate a `mailto:` link using the `ActionLink` method by specifying the desired email address as the route value and the protocol as `mailto`. For example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>@Html.ActionLink("Send Email", "Contact", "Home", null, new { href = "mailto:example@example.com" })</b></span></p><p style="text-align: justify;"><span style="font-size: large;">This will generate an HTML anchor tag with the link text "Send Email" and the URL as `mailto:example@example.com`, allowing users to open their default email client with the specified email address.</span></p><p style="text-align: justify;"><br /></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you generate an `ActionLink` with an HTML fragment instead of plain text?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, you can generate an `ActionLink` with an HTML fragment instead of plain text by using the `Html.Raw` method to render the HTML. For example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>@Html.ActionLink(Html.Raw("<span class='my-class'>Home</span>"), "Index", "Home")</b></span></p><p style="text-align: justify;"><span style="font-size: large;">This will generate an HTML anchor tag with the link text "Home" wrapped in a `<span>` element with the CSS class "my-class".</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you include additional query string parameters in the `ActionLink` URL?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">To include additional query string parameters in the `ActionLink` URL, you can add them as key-value pairs in the `routeValues` object. For example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>@Html.ActionLink("Search", "Index", "Product", new { category = "electronics", page = 1 }, null)</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In this example, the `category` and `page` parameters are included as query string parameters in the generated URL.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the purpose of the `fragment` parameter in the `ActionLink` method?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">The `fragment` parameter in the `ActionLink` method represents the fragment identifier or anchor within the target URL. It allows you to navigate to a specific section or element within the target page. For example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b> @Html.ActionLink("Go to Section", "Index", "Home", null, null, "section1")</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In this example, clicking the generated link will navigate to the "section1" anchor within the target page.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you specify an HTTP method other than GET in the `ActionLink` method?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">The `ActionLink` method generates an HTML anchor tag, which by default performs a GET request. To specify a different HTTP method, you can use the `data-*` attributes and JavaScript/jQuery to handle the desired action. For example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b> @Html.ActionLink("Delete", "Delete", "Product", new { id = Model.Id }, new { @class = "delete-link", data_method = "delete" })</b></span></p><p style="text-align: justify;"><span style="font-size: large;">In this example, the `data-method` attribute is set to "delete", and you can handle the action using JavaScript/jQuery to perform a DELETE request.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you generate an `ActionLink` with an image instead of text?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">To generate an `ActionLink` with an image instead of text, you can use HTML and CSS to create a clickable image element within the `ActionLink`. For example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b> @Html.ActionLink("", "Index", "Home", null, new { @class = "image-link" })</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">You can then apply CSS to the `image-link` class to set the background image and adjust its size and position.</span></p>Suthahar

How is it different from other collection classes?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">StringCollection in C# is a collection class specifically designed to store and manipulate a collection of string values. It is part of the `System.Collections.Specialized` namespace.</span></p><p style="text-align: justify;"><span style="font-size: large;">The difference between StringCollection and other collection classes like ArrayList is that StringCollection is strongly-typed and can only store string values. It provides additional methods and events specific to string manipulation, such as Insert, Remove, IndexOf, and StringCollectionChanged.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is a Hashtable in C#? How does it differ from other collection classes?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">A Hashtable in C# represents a collection of key-value pairs, where each key is unique. It provides fast lookup and retrieval of values based on the associated keys using a hashing algorithm. It is part of the `System.Collections` namespace.</span></p><p style="text-align: justify;"><span style="font-size: large;">The main difference between Hashtable and other collection classes like ArrayList is that Hashtable requires unique keys and allows for efficient key-based lookup. It does not preserve the order of elements. The keys and values in a Hashtable can be of any type.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is a SortedList in C#? How is it different from other collection classes?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">A SortedList in C# is a collection of key-value pairs that are sorted by the keys. It provides fast lookup by key and maintains the elements in a sorted order based on the keys. It is part of the `System.Collections` namespace.</span></p><p style="text-align: justify;"><span style="font-size: large;">The key difference between SortedList and other collection classes is that SortedList automatically maintains the elements in a sorted order based on the keys. This allows for efficient searching and retrieval operations. However, SortedList may have slightly slower insertion and removal compared to other non-sorted collections.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is ListDictionary in C#? How does it differ from other dictionary classes?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">ListDictionary in C# is a simple implementation of the IDictionary interface using a singly linked list. It is part of the `System.Collections` namespace.</span></p><p style="text-align: justify;"><span style="font-size: large;">ListDictionary differs from other dictionary classes like Hashtable and SortedList in terms of its implementation and performance characteristics. ListDictionary is optimized for small collections or scenarios where memory usage and performance are not critical factors. It provides dictionary-like functionality with basic operations such as Add, Remove, Contains, and accessing elements by key. However, ListDictionary does not guarantee any specific order for its elements.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is a HybridDictionary in C#? How does it differ from other dictionary classes?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">A HybridDictionary in C# is a dictionary class that uses a list-based implementation for small collections and a hashtable-based implementation for larger collections. It is part of the `System.Collections.Specialized` namespace.</span></p><p style="text-align: justify;"><span style="font-size: large;">The main difference between HybridDictionary and other dictionary classes like Hashtable is its hybrid implementation. It dynamically switches between a list-based implementation and a hashtable-based implementation based on the number of elements in the collection. This allows for memory-efficient usage for small collections and optimized performance for larger collections.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is a Queue in C#?

How does it differ from other collection classes?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">A Stack in C# represents a last-in, first-out (LIFO) collection of objects. It is part of the `System.Collections` namespace.</span></p><p style="text-align: justify;"><span style="font-size: large;">The main difference between a Stack and other collection classes is that it follows the LIFO principle. Elements are added to and removed from the top of the stack. It provides operations such as Push (add an element to the top), Pop (remove and return the top element), and Peek (retrieve the top element without removing it).</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is a HashSet in C#?

style="text-align: justify;"><span style="font-size: x-large;"><b><span>Best practices and tips to keep in mind:</span></b></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Use the appropriate collection type:</b> Choose the collection type that best suits your needs based on the specific requirements of your application. For example, use ArrayList for a dynamically resizable array, Hashtable for a collection of key-value pairs, or LinkedList for efficient insertion and removal operations.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Specify the collection type explicitly:</b> When declaring and working with non-generic collections, it's a good practice to explicitly specify the collection type. For example, instead of using the non-generic `ArrayList`, use the generic `List<T>` with the appropriate type parameter.</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>Avoid mixing types in collections:</b> Non-generic collections like ArrayList allow storing elements of different types. However, it's generally recommended to avoid mixing types within a collection to maintain type safety and clarity in your code.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Use the appropriate methods and properties: </b>Each non-generic collection provides specific methods and properties tailored to its functionality. Familiarize yourself with the available methods and use them appropriately. For example, use `Add` to add elements, `Remove` to remove elements, and `Count` to get the number of elements.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Be cautious of boxing and unboxing:</b> Non-generic collections store elements as objects, which can lead to boxing and unboxing operations when working with value types. Be aware of the performance implications of boxing and unboxing, and consider using generic collections when working with value types to avoid these operations.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Prefer generic collections when possible: </b>Whenever possible, use the generic versions of collections (such as `List<T>`, `Dictionary<TKey, TValue>`, etc.) instead of their non-generic counterparts. Generic collections provide better type safety, improved performance, and avoid the need for casting or boxing/unboxing.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Consider using collection initializers: </b>Collection initializers provide a concise syntax for initializing collection objects with a set of elements. Take advantage of collection initializers to simplify the code when adding elements to non-generic collections.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Ensure thread safety if required: </b>Non-generic collections are not inherently thread-safe. If you need to access a collection from multiple threads concurrently, consider using thread-safe techniques like locking or using concurrent collections (available in the `System.Collections.Concurrent` namespace).</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Dispose of IDisposable collections:</b> Some non-generic collections, such as `Hashtable`, may implement the `IDisposable` interface. If you use such collections and they are no longer needed, make sure to dispose of them properly to release any resources they may hold.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Follow naming conventions: </b>When naming your collection variables or types, follow the naming conventions recommended by the C# programming guidelines. Use meaningful and descriptive names to enhance code readability and maintainability.</span></p><p style="text-align: justify;"><span style="font-size: large;">By following these best practices and tips, you can effectively work with non-generic collections in C# and write clean, maintainable code. However, it's generally recommended to use generic collections whenever possible to take advantage of their type safety, improved performance, and better code readability.</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Naming conventions for collections</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Use plural names:</b> Use plural names for collection variables to indicate that they represent multiple elements. For example, use `customers` instead of `customer` for a collection of customer objects.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Use descriptive names:</b> Choose meaningful and descriptive names that accurately represent the purpose or content of the collection. Avoid using generic names like `list` or `collection` unless they are appropriate in the context.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Avoid type-specific names:</b> Avoid including the type name in the collection variable name. For example, instead of naming a collection of strings as `stringList`, simply use `names` or a more descriptive name related to the specific purpose of the collection.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Prefer specific collection names: </b>If possible, use more specific collection names that indicate the purpose or usage of the collection. For example, use `orderItems` instead of `items` if the collection represents order items.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Use camelCase:</b> Use camelCase for naming collection variables, starting with a lowercase letter. For example, use `userList` instead of `UserList` or `user_list`.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Avoid Hungarian notation:</b> Avoid using Hungarian notation or prefixes to indicate the collection type, such as `lst`, `arr`, or `dict`. The type information should be clear from the variable declaration and context.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Be consistent:</b> Maintain consistency in naming conventions throughout your codebase. If you follow a specific naming convention for collections, stick to it consistently across your code.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><a href="https://xamarininterviewquestion.blogspot.com/2023/04/top-interview-questions-and-answers.html" rel="nofollow" target="_blank"><span style="font-size: medium;">More Questions</span></a></p><div class="separator" style="clear: both; text-align: justify;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMe4W9E6nGIW7QJlnTqzXlkR7_TVXWnIE6_2yAb_sloAwGlNy5Pk8XBP2YvQYZNn_jPpCDfXTKwRLwqlZk4WcWRt6Z347kWsnDICbCCmNtPN0wPg3QrQv8MFHSfG_815Epfi2MGe95X9joJXbcnW9Uc6Hn6xPRDDrYBR0Y0MMT4vcP1g-wDhV1kSDTvYI/s438/image.png" style="margin-left: 1em; margin-right: 1em;"><span style="font-size: medium;"><img alt="Best Dotnet Training in Tamil" border="0" data-original-height="438" data-original-width="292" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMe4W9E6nGIW7QJlnTqzXlkR7_TVXWnIE6_2yAb_sloAwGlNy5Pk8XBP2YvQYZNn_jPpCDfXTKwRLwqlZk4WcWRt6Z347kWsnDICbCCmNtPN0wPg3QrQv8MFHSfG_815Epfi2MGe95X9joJXbcnW9Uc6Hn6xPRDDrYBR0Y0MMT4vcP1g-wDhV1kSDTvYI/w426-h640/image.png" title="Best Dotnet Training in Tamil" width="426" /></span></a></div><span style="font-size: medium;"><div style="text-align: justify;"><br /></div></span><div class="separator" style="clear: both; text-align: justify;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMeckfFqPhrQOfzYi3OnEf3onsKYB7OaANhPjukqI1eI5x9cEKvty2cZGJd6R3dLZBfuR5LrCmwHZhuvUMJ_DG7rVgBgqIHvJ0EEuAmX8kohdCOjDuqgWbxewsdH6LcBNnNKHBOQPtlTWfdISa71Y3MBoo4fZBvSuLAmsV3EN8C5dkl92kl8Y9QM9Uf4k/s960/Helping.gif" style="margin-left: 1em; margin-right: 1em;"><span style="font-size: medium;"><img alt="Best Dotnet Training in Tamil" border="0" data-original-height="960" data-original-width="720" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMeckfFqPhrQOfzYi3OnEf3onsKYB7OaANhPjukqI1eI5x9cEKvty2cZGJd6R3dLZBfuR5LrCmwHZhuvUMJ_DG7rVgBgqIHvJ0EEuAmX8kohdCOjDuqgWbxewsdH6LcBNnNKHBOQPtlTWfdISa71Y3MBoo4fZBvSuLAmsV3EN8C5dkl92kl8Y9QM9Uf4k/w480-h640/Helping.gif" title="Best Dotnet Training in Tamil" width="480" /></span></a></div><span style="font-size: medium;"><div style="text-align: justify;"><br /></div></span><p style="text-align: justify;"><br /></p>Suthahar Jegatheesanhttp://www.blogger.com/profile/14709587036173890626noreply@blogger.com0tag:blogger.com,1999:blog-5602264950125608941.post-14073341825675810492023-07-14T23:09:00.003-07:002023-07-14T23:34:32.024-07:00😍 𝐅𝐫𝐞𝐞!!

It contains the common HTML structure, header, footer, and other elements that remain consistent across multiple pages. Views can specify a Layout to inherit from, allowing them to provide content within the defined structure.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you pass data from a Controller to a View in ASP.NET Core?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Data can be passed from a Controller to a View in ASP.NET Core using ViewBag, ViewData, or strongly-typed models. ViewBag and ViewData are dynamic objects that allow you to store and retrieve data within the Controller and access it in the corresponding View. Strongly-typed models involve creating a custom class to represent the data and passing an instance of that class to the View.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the role of the @ symbol in Razor Views?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In Razor Views, the @ symbol is used to switch between HTML markup and C# code. It allows developers to embed C# code within the HTML markup and vice versa. For example, @Model.PropertyName is used to display a property value from the model, and @{ ... } is used to enclose a block of C# code.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you include C# code in HTML markup in Razor Views?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">C# code can be included in HTML markup in Razor Views using the @ symbol. For example, you can use @if, @foreach, @switch, or @Html helper methods to write conditional statements, loops, and generate dynamic content.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you use C# code to generate HTML elements dynamically in Razor Views?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">You can use C# code in Razor Views to dynamically generate HTML elements by using loops, conditional statements, and HTML helpers. For example, you can use a foreach loop to iterate over a collection and generate HTML elements dynamically based on the data.</span></p>Suthahar Jegatheesanhttp://www.blogger.com/profile/14709587036173890626noreply@blogger.com0tag:blogger.com,1999:blog-5602264950125608941.post-71068365387737740272023-07-10T16:32:00.000-07:002023-07-10T16:32:30.258-07:00ASP.NET MVC Interview questions and answers related to ViewBag, ViewData, and TempData<p style="text-align: justify;"><span style="font-size: x-large;"></span></p><div class="separator" style="clear: both; text-align: center;"><span style="font-size: x-large;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_U8nN8q2X30jDcwG3VOvM2KqBeKhAsODslAUkyn7KZFBtS56UpSA_XbSfzJYpUYc6PGb_dmbFW-t9oX2dZpHykAJOCwv-tJaXm8l9mVTuN1gFNeA6KnYvTeOgn2UbpIoWYxD_pg1nT57txGOGTrKiYrwRKtG3vUAx50mVqDWtI5dpb8ljBPfa1JFmiLQ/s275/download.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="183" data-original-width="275" height="405" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_U8nN8q2X30jDcwG3VOvM2KqBeKhAsODslAUkyn7KZFBtS56UpSA_XbSfzJYpUYc6PGb_dmbFW-t9oX2dZpHykAJOCwv-tJaXm8l9mVTuN1gFNeA6KnYvTeOgn2UbpIoWYxD_pg1nT57txGOGTrKiYrwRKtG3vUAx50mVqDWtI5dpb8ljBPfa1JFmiLQ/w608-h405/download.png" width="608" /></a></span></div><span style="font-size: x-large;"><b><br /></b></span><p></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is ViewBag in ASP.NET MVC?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">ViewBag is a dynamic property that is part of the ViewData dictionary and is used to pass data from the controller to the view.

They are not persisted across subsequent requests. TempData, on the other hand, persists data for the duration of the current request and the subsequent redirect request.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What happens if you try to access TempData in a different action without redirecting?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">If you try to access TempData in a different action without redirecting, the data stored in TempData will not be available. TempData is cleared automatically after it is accessed or at the end of the current request.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you pass complex objects using ViewBag, ViewData, or TempData?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">ViewBag and ViewData allow you to pass complex objects, but you need to cast them appropriately in the view. TempData, however, only supports passing simple objects. If you need to pass complex objects through redirects, it is recommended to use other techniques like query parameters, session state, or database storage.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the recommended way to pass data from the controller to the view in ASP.NET MVC?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The recommended way to pass data from the controller to the view in ASP.NET MVC is to use strongly-typed models. By defining a model class and passing an instance of that model to the view, you can have strong typing, compile-time checking, and improved code readability. ViewBag, ViewData, and TempData are considered less preferable compared to strongly-typed models.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How does TempData handle multiple redirects in ASP.NET MVC?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">TempData is designed to persist data across redirects until it is accessed. If there are multiple redirects in a sequence, TempData will preserve the data until it is read in one of the actions. Once accessed, the data is marked for deletion, and subsequent redirects will not have access to that data.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you provide an example of using ViewData in ASP.NET MVC?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Here's an example of using ViewData to pass data from the controller to the view:</span></p><p style="text-align: justify;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjVfMfm9Eajn8kzzka-txyqAuQbDygm6P3qRrdfPUlImnR1rle7_eO7jlHn6NFWoQJnr0xuFlcKDxodx8rGVUQ59VHg85yB9lR69U_2xUKIYzuwO3G8j4dgTcb_yYwtM-GuCLJ27SgwE_zi1LcZQDIdThmrambQIwfGtqRPODNokOdv3_Jzzpbj6su_yzo" style="margin-left: 1em; margin-right: 1em;"><img data-original-height="221" data-original-width="526" height="268" src="https://blogger.googleusercontent.com/img/a/AVvXsEjVfMfm9Eajn8kzzka-txyqAuQbDygm6P3qRrdfPUlImnR1rle7_eO7jlHn6NFWoQJnr0xuFlcKDxodx8rGVUQ59VHg85yB9lR69U_2xUKIYzuwO3G8j4dgTcb_yYwtM-GuCLJ27SgwE_zi1LcZQDIdThmrambQIwfGtqRPODNokOdv3_Jzzpbj6su_yzo=w640-h268" width="640" /></a></div><br /><span style="font-size: large;">In the corresponding view, you can access the data using the ViewData dictionary:</span><p></p><p style="text-align: justify;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEho9qAT4ToLQWGZdSoh2VAuBFZv8DQjRhVQDnPwVyyCGL-TTriurfFJzkQNq_9_Y2MeUOab9TvJ-wZSb8ZD4AtwbVy4S6JtJ8rHkMHQTjDY1oZcEHgSqepThb6k2cIc6A9Y5K6EHLUhmnqq6FTAHsZ21lFPdDw26H1KnysMoB5Hb8qwMnrUW9ZSFztAtX8" style="margin-left: 1em; margin-right: 1em;"><img data-original-height="58" data-original-width="419" height="88" src="https://blogger.googleusercontent.com/img/a/AVvXsEho9qAT4ToLQWGZdSoh2VAuBFZv8DQjRhVQDnPwVyyCGL-TTriurfFJzkQNq_9_Y2MeUOab9TvJ-wZSb8ZD4AtwbVy4S6JtJ8rHkMHQTjDY1oZcEHgSqepThb6k2cIc6A9Y5K6EHLUhmnqq6FTAHsZ21lFPdDw26H1KnysMoB5Hb8qwMnrUW9ZSFztAtX8=w640-h88" width="640" /></a></div><br /><br /><p></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What are the advantages of using strongly-typed models over ViewBag and ViewData?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Strongly-typed models provide compile-time checking, type safety, and improved code readability. They allow you to access data using strongly-typed properties in the view, reducing the risk of runtime errors. With ViewBag and ViewData, you need to rely on dynamic typing and string keys, which can be error-prone.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you explain the role of ViewDataDictionary in ASP.NET MVC?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">ViewDataDictionary is a dictionary-like object that contains data used to communicate between the controller and the view. It is the underlying implementation of both ViewBag and ViewData. It provides a way to store and retrieve data using string keys.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How can you maintain data across multiple requests without using TempData?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">If you want to maintain data across multiple requests without using TempData, you can consider using session state or storing the data in a persistent storage medium such as a database or cookies. Session state allows you to store data on the server and associate it with a user's session, while persistent storage options provide long-term data persistence.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can TempData be used to pass data between different controllers?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, TempData can be used to pass data between different controllers. TempData uses the session state mechanism to store data, so as long as the controllers are part of the same session, TempData can be accessed and used to pass data between them.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Is it possible to share data between partial views using ViewBag or ViewData?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, you can share data between partial views using ViewBag or ViewData. Since ViewBag and ViewData are available in the parent view as well as partial views, you can set data in the parent view's controller and access it in the partial view or vice versa.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What are some alternatives to ViewBag, ViewData, and TempData?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Some alternatives to ViewBag, ViewData, and TempData include using strongly-typed models, using session state, passing data through query parameters or form inputs, using cookies, or storing data in a database. The choice of the alternative depends on the specific requirements and context of your application.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you use TempData to pass data between different action methods within the same controller?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, TempData can be used to pass data between different action methods within the same controller. TempData persists data for the duration of the current request and the subsequent redirect request, allowing you to pass data between different actions in the same controller.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><br /></p>Suthahar Jegatheesanhttp://www.blogger.com/profile/14709587036173890626noreply@blogger.com0tag:blogger.com,1999:blog-5602264950125608941.post-28883181181010807712023-07-10T05:58:00.000-07:002023-07-10T05:58:24.096-07:00 .NET Core MVC Interview questions related to Session, Cookies, and Query String<p style="text-align: justify;"></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrq8B0liPecZXFEwaZzdfLdh0HfpnWHMJCzRtPiFr2zcKTUF9CQqvvsFKXjN91uMluD1--JHMYjNJz6g5STBcyygxPTv9-XzSvk3qV9VbgGD7mikV8ahnbfiMM9DLvtAAUt7hqWF6rgAmW_a659CYKoiamzl83c_qKLu68rk1mITjXIexiSJxSvmW_tk0/s395/images.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="127" data-original-width="395" height="206" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrq8B0liPecZXFEwaZzdfLdh0HfpnWHMJCzRtPiFr2zcKTUF9CQqvvsFKXjN91uMluD1--JHMYjNJz6g5STBcyygxPTv9-XzSvk3qV9VbgGD7mikV8ahnbfiMM9DLvtAAUt7hqWF6rgAmW_a659CYKoiamzl83c_qKLu68rk1mITjXIexiSJxSvmW_tk0/w640-h206/images.png" width="640" /></a></div><br /><span style="font-size: medium;"><br /></span><p></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Session:</b></span></p><p style="text-align: justify;"><b><span style="font-size: x-large;">How can you check if a session variable exists?</span></b></p><p style="text-align: justify;"><span style="font-size: medium;">You can use the `ContainsKey` method of the `HttpContext.Session` property to check if a session variable exists.

It specifies a set of methods, properties, and events that the implementing class must provide. Interfaces provide a way to achieve multiple inheritances in C#.</span></p><p style="text-align: justify;"><span style="font-size: large;">Example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public interface</span> IShape</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">void</span> Draw();</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">double</span> CalculateArea();</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public class </span>Circle : IShape</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> public void</span> Draw()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #38761d;">Console</span>.<span style="color: #bf9000;">WriteLine</span>(<span style="color: red;">"Drawing a circle"</span>);</span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: large;"> <span style="color: #2b00fe;"> public double</span> CalculateArea()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Calculate and return the area of the circle</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">return</span> <span style="color: #ff00fe;">Math</span>.<span style="color: #bf9000;">PI</span> * <span style="color: #134f5c;">radius</span> * <span style="color: #134f5c;">radius</span>;</span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>When do we use interfaces?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">Interfaces are used when we want to define a contract that multiple classes can adhere to. It is commonly used for achieving abstraction, providing a common set of methods across different classes, and facilitating loose coupling between components.</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is inheritance? Why do we use inheritance?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">Inheritance is a mechanism in object-oriented programming where one class inherits properties and behaviors from another class. It allows the creation of hierarchical relationships between classes. We use inheritance to promote code reuse, enhance modularity, and establish an "is-a" relationship between classes.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How many types of access modifiers are there in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">C# provides five access modifiers: public, private, protected, internal, and protected internal.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>When do we use the private modifier?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">The private access modifier is used to restrict access to members within the same class. It ensures that the member is only accessible from within the class itself and not from any derived classes or external code.</span></p><p style="text-align: justify;"><span style="font-size: large;">Example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public class</span> MyClass</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> private int </span>myPrivateField;</span></p><p style="text-align: justify;"><span style="font-size: large;"> <span style="color: #2b00fe;"> private void </span>MyPrivateMethod()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Code here</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is method overloading in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">Method overloading allows us to define multiple methods with the same name but different parameters in the same class.

It is used to achieve polymorphism and to specialize behavior in derived classes.</span></p><p style="text-align: justify;"><span style="font-size: large;">Example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public class</span> Shape</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> public virtual void</span> Draw()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #38761d;">Console</span>.<span style="color: #bf9000;">WriteLine</span>(<span style="color: red;">"Drawing a shape"</span>);</span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public class </span>Circle : Shape</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> public override void</span> Draw()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #38761d;">Console</span>.<span style="color: #bf9000;">WriteLine</span>(<span style="color: red;">"Drawing a circle"</span>);</span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How do we use exception handling in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">Exception handling in C# is done using try-catch-finally blocks. The code that may raise an exception is placed inside the try block, and any potential exceptions are caught and handled in the catch block. The finally block is used to execute code that should always run, regardless of whether an exception occurs or not.</span></p><p style="text-align: justify;"><span style="font-size: large;">Example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">try</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Code that may raise an exception</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">catch</span> (<span style="color: #2b00fe;">Exception</span> ex)</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Handle the exception</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;">finally</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Code that always executes</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What are the blocks available in a try-catch in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">The blocks available in a try-catch statement in C# are:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">try: Contains the code that may raise an exception.</span></li><li><span style="font-size: medium;">catch:</span><span style="font-size: large;"> Catches and handles the exception.</span></li><li><span style="font-size: medium;">finally: Contains code that always executes, whether an exception occurs or not.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>When does the catch block execute?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">The catch block executes when an exception is thrown inside the try block that matches the type of the caught exception.

It ensures that the Dispose method of an object is called when it goes out of scope. Here's an example of its usage:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">using </span>(<span style="color: #2b00fe;">var </span>connection = <span style="color: #2b00fe;">new </span><span style="color: #38761d;">SqlConnection</span>(connectionString))</span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Code block where the connection is used</span></span></p><p style="text-align: justify;"><span style="color: #274e13; font-size: medium;"> // The connection will be automatically disposed at the end of the block</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Types of Constructors</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In C#, constructors are special methods used for initializing objects. There are three types of constructors:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">Default Constructor: It has no parameters and is automatically generated if no constructor is defined explicitly.</span></li><li><span style="font-size: medium;">Parameterized Constructor: It accepts parameters and initializes the object with provided values.</span></li><li><span style="font-size: medium;">Copy Constructor: It creates a new object by copying the values from an existing object.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Object with a Class with a Private Constructor</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">If a class has a private constructor, objects cannot be directly instantiated outside the class. However, the class itself can create instances using static methods or properties within its scope. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">public class</span> <span style="color: #38761d;">MyClass</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">private </span><span style="color: #38761d;">MyClass</span>()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Private constructor</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: large;"> </span><span style="color: #2b00fe; font-size: large;"> public static</span><span style="font-size: large;"> </span><span style="color: #38761d; font-size: large;">MyClass </span><span style="font-size: large;">CreateInstance()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> return new </span><span style="color: #38761d;">MyClass</span>();</span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="color: #274e13; font-size: large;">// Creating an object using the static method</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">var </span>myObject = <span style="color: #38761d;">MyClass</span>.CreateInstance();</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between String and StringBuilder</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In C#, '<b>String</b>' is an immutable type, which means once created, it cannot be changed. '<b>StringBuilder</b>', on the other hand, is a mutable type specifically designed for efficient string manipulation. 'StringBuilder' is preferred for concatenating multiple strings or when frequent modifications to a string are required.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Sealed Class</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">A sealed class in C# is a class that cannot be inherited. It is marked with the 'sealed' keyword to prevent other classes from deriving from it. Sealed classes are used when you want to restrict inheritance to maintain control over the behavior and implementation of a class.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Extension Method</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An extension method in C# allows adding new methods to an existing type without modifying the original type. It is defined in a static class and must be a static method. Extension methods are called as if they were instance methods of the extended type. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">public static class </span><span style="color: #38761d;">StringExtensions</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">public static bool</span> IsNullOrEmpty(<span style="color: #2b00fe;">this string</span> value)</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">return string</span>.<span style="color: #7f6000;">IsNullOrEmpty</span>(value);</span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #274e13;">// Usage of the extension method</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">string </span>myString = <span style="color: red;">"Hello"</span>;</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">bool </span>isEmpty = myString.<span style="color: #7f6000;">IsNullOrEmpty</span>();</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between Private Constructor and Static Constructor</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">A private constructor is used to restrict the creation of objects from outside the class, while a static constructor is used to initialize the class itself. A private constructor can be called within the class, whereas a static constructor is invoked automatically before any static members of the class are accessed.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between 'ref' and 'out'</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Both 'ref' and 'out' are used to pass arguments by reference in C#. However, there is a key difference:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">'ref' requires the variable to be initialized before passing it to the method, whereas 'out' does not.</span></li><li><span style="font-size: medium;">In 'ref', the variable passed to the method must be initialized, but in 'out', it must be assigned a value within the method before returning.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Encapsulation</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Encapsulation is an object-oriented programming concept that combines data and methods into a single unit called a class. It provides data abstraction, hiding the internal details of how data is stored or processed, and exposes only necessary information through public methods or properties.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Types of Access Modifiers</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In C#, there are five access modifiers:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;"> Public: Accessible from anywhere.</span></li><li><span style="font-size: medium;"> Private: Accessible only within the same class.</span></li><li><span style="font-size: medium;"> Protected: Accessible within the same class and derived classes.</span></li><li><span style="font-size: medium;"> Internal: Accessible within the same assembly.</span></li><li><span style="font-size: medium;"> Protected Internal: Accessible within the same assembly and derived classes.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How to access the protected modifier?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The protected modifier in object-oriented programming languages allows access to a member within the same class and its subclasses. To access a protected member in C#, you can create an instance of the subclass and access the protected member using the dot operator. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">public class </span><span style="color: #38761d;">MyBaseClass</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> protected int</span> myProtectedField;</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public class</span> <span style="color: #38761d;">MySubClass </span>: <span style="color: #38761d;">MyBaseClass</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> public void</span> AccessProtectedField()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> myProtectedField = 10; <span style="color: #274e13;">// Accessing protected field</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is garbage collection?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Garbage collection is an automatic memory management technique used in languages like C# to reclaim memory occupied by objects that are no longer in use. The garbage collector identifies and frees up memory that is no longer referenced by any active objects in the program, preventing memory leaks and reducing manual memory management overhead.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between abstract class and interface?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">In C#, an abstract class and an interface both provide a way to define contracts for derived classes, but they have some key differences. </span></p><p style="text-align: justify;"><span style="font-size: large;"><b>Abstract class</b>: An abstract class can have both defined and undefined (abstract) members. It can provide partial implementation of methods and can have fields and constructors. It cannot be instantiated directly but serves as a base for derived classes to inherit from. A class can inherit from only one abstract class.</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>Interface</b>: An interface is a contract that defines a set of methods and properties. It only contains method signatures, properties, events, and indexers. It cannot have fields or constructors. A class can implement multiple interfaces, enabling multiple inheritance of behavior.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How to implement multiple inheritance in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">C# does not support multiple inheritance of classes, but you can achieve a similar effect using interfaces. By implementing multiple interfaces, a class can inherit and define the behavior of each interface. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">public interface</span> <span style="color: #38761d;">IInterface1</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">void </span>Method1();</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public interface</span> <span style="color: #38761d;">IInterface2</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">void </span>Method2();</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">public class </span><span style="color: #38761d;">MyClass </span>: <span style="color: #38761d;">IInterface1</span>, <span style="color: #38761d;">IInterface2</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">{</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> public void</span> Method1()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Implementation</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: large;"> <span style="color: #2b00fe;"> public void </span>Method2()</span></p><p style="text-align: justify;"><span style="font-size: medium;"> {</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> // Implementation</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> }</span></p><p style="text-align: justify;"><span style="font-size: medium;">}</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is an abstract class?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An abstract class is a class that cannot be instantiated directly and is intended to serve as a base for other classes to inherit from. It can contain abstract and non-abstract members. Abstract members do not have an implementation in the abstract class and must be implemented in derived classes. An abstract class is declared using the `abstract` keyword.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you create an object of an abstract class? Why?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, you cannot create an object of an abstract class. Abstract classes are incomplete and contain one or more abstract members without implementation. They are designed to be inherited by derived classes, which provide implementations for abstract members. Attempting to instantiate an abstract class directly would result in a compilation error.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between abstraction and abstract class?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Abstraction is a broader concept that refers to the process of hiding unnecessary details and exposing only essential features to the user. It allows users to work with high-level concepts without worrying about the underlying implementation.</span></p><p style="text-align: justify;"><span style="font-size: large;">An abstract class is a specific implementation in object-oriented programming that allows creating classes with both defined and undefined</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is polymorphism?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Polymorphism is a fundamental concept in object-oriented programming that allows objects of different types to be treated as objects of a common base type. It enables code to be written that can work with objects of multiple classes, providing flexibility and extensibility. Polymorphism can be achieved through method overriding and method overloading.</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is runtime polymorphism?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">Runtime polymorphism, also known as dynamic polymorphism, occurs when the appropriate method implementation is determined at runtime based on the actual type of the object. It is achieved through method overriding, where a derived class provides its own implementation of a method defined in the base class. The decision of which implementation to execute is made dynamically during program execution.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is method overriding?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">Method overriding is a feature in object-oriented programming that allows a subclass to provide its own implementation of a method that is already defined in its superclass. The overridden method in the subclass must have the same name, return type, and parameter list as the method in the superclass. It allows for the specialization of behavior in derived classes.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Keywords in method overriding include:</b></span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">`<b>override</b>`: Used in the derived class to indicate that a method is intended to override a method in the base class.</span></li><li><span style="font-size: medium;">`<b>base</b>`: Used within the derived class to refer to the base class implementation of the overridden method.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: large;">Method overriding is applicable to classes that have an inheritance relationship, where the derived class extends or inherits from the base class.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Main objects in ADO.NET?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">In ADO.NET (ActiveX Data Objects for .NET), the main objects include:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;"><b>Connection</b>: Represents a connection to a data source.</span></li><li><span style="font-size: medium;"><b>Command</b>: Represents an SQL statement or a stored procedure to execute against a data source.</span></li><li><span style="font-size: medium;"><b>DataReader</b>: Provides a fast, forward-only, read-only stream of data from a data source.</span></li><li><span style="font-size: medium;"><b>DataSet</b>: Represents an in-memory cache of data, which can contain multiple DataTable objects.</span></li><li><span style="font-size: medium;"><b>DataTable</b>: Represents a table of data in memory, consisting of rows and columns.</span></li><li><span style="font-size: medium;"><b>DataAdapter</b>: Serves as a bridge between a DataSet and a data source, enabling data retrieval and update operations.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between DataSet and DataTable?</b></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>DataSet</b>: A DataSet is an in-memory cache of data that can hold multiple DataTable objects along with their relationships. It represents a disconnected set of data and can persist its contents in XML format. It can hold data from multiple tables and can be used for offline data manipulation and synchronization.</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>DataTable</b>: A DataTable represents a single table of data within a DataSet. It consists of rows and columns and is similar to a table in a relational database. It stores data in a tabular form and provides methods and properties for data manipulation and querying.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What are all the different types of execute methods in ADO.NET?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In ADO.NET, the different types of execute methods commonly used are:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">`<b>ExecuteNonQuery()</b>`: Executes a command that does not return any result set, such as an INSERT, UPDATE, DELETE, or DDL statement.</span></li><li><span style="font-size: medium;">`<b>ExecuteScalar()</b>`: Executes a command and returns the value of the first column of the first row in the result set.

It is typically used when a single value is expected as the result, such</span><span style="font-size: large;"> as retrieving a count or an aggregated value. It returns an object that needs to be cast to the appropriate type.</span></p><p style="text-align: justify;"><span style="font-size: large;">`<b>ExecuteNonQuery()</b>`: It is used to execute a command that does not return any result set, such as INSERT, UPDATE, DELETE, or DDL statements.

It provides a dynamic and flexible way to present and manipulate data from a DataTable. DataView can be used to apply sorting and filtering conditions to a DataTable, and it also supports data binding with UI controls for efficient data presentation and manipulation.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Types of authentication in SQL?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL, the common types of authentication include:</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Windows Authentication:</b> Uses the credentials of the currently logged-in Windows user to authenticate and authorize access to the SQL Server. It relies on Windows security and Active Directory.</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>SQL Server Authentication:</b> Requires a username and password specific to SQL Server.

It ensures that values in a column match values in another table's primary key.</span></li><li><span style="font-size: medium;"><b>Check: </b>A check constraint validates the values in a column to meet a specific condition or range of values.</span></li><li><span style="font-size: medium;"><b>Not Null:</b> A not null constraint ensures that a column does not contain any null values.</span></li><li><span style="font-size: medium;"><b>Default:</b> A default constraint provides a default value for a column if no value is specified during an insert operation.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Queries under DML?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">DML (Data Manipulation Language) in SQL is used to modify and retrieve data from tables. Common DML queries include:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>SELECT: </b>Retrieves data from one or more tables based on specified conditions.</span></li><li><span style="font-size: medium;"><b>INSERT:</b> Inserts new rows of data into a table.</span></li><li><span style="font-size: medium;"><b>UPDATE:</b> Modifies existing data in one or more rows of a table.</span></li><li><span style="font-size: medium;"><b>DELETE:</b> Removes one or more rows of data from a table.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between primary key and unique key?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">The primary key and unique key are both used to enforce uniqueness in SQL, but they have some differences:</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>Primary Key: </b>It uniquely identifies each row in a table and ensures that the identified column(s) have unique values. It is a combination of the unique and not null constraints. Only one primary key can be defined per table.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Unique Key:</b> It ensures that the identified column(s) have unique values. Unlike a primary key, a table can have multiple unique keys. Unique keys can allow null values, except for the columns defined as the primary key.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can we use multiple primary keys?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, a table can have only one primary key. The primary key uniquely identifies each row in a table. However, you can use composite primary keys by combining two or more columns to create a unique identifier for a row.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What constraint do you use to check some condition?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">To check a condition, you can use the CHECK constraint in SQL. The CHECK constraint allows you to specify a condition that must be satisfied for each row in a table. If the condition evaluates to false, the constraint prevents the insertion or modification of the row.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between DELETE and TRUNCATE?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The DELETE and TRUNCATE statements are used to remove data from tables in SQL, but they differ in their behavior:</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>DELETE:</b> The DELETE statement is a DML statement that removes specific rows from a table based on specified conditions. It provides more flexibility by allowing you to specify complex filtering criteria. DELETE operation can be rolled back using a transaction.</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>TRUNCATE:</b> The TRUNCATE statement is a DDL statement that removes all rows from a table. It is faster than DELETE because it does not generate individual undo logs for each deleted row. TRUNCATE operation cannot be rolled back as it is considered a non-logged operation.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Tell me a TRUNCATE query.</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The TRUNCATE query is used to remove all rows from a table. The syntax for TRUNCATE is as follows:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">TRUNCATE TABLE</span> table_name;</span></p><p style="text-align: justify;"><span style="font-size: large;">Replace `table_name` with the name of the table you want to truncate.

Identity columns automatically generate incrementing numeric values for each new row inserted into a table. Sequences generate a sequence of numeric values. The specific syntax for implementing auto-generated fields may vary depending on the database system you are using.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between stored procedure and function?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The main differences between stored procedures and functions are:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>Purpose</b>: A stored procedure is primarily used to perform an action or a series of actions, such as modifying data, executing complex logic, or generating reports. A function is designed to return a single value or a table of values.</span></li><li><span style="font-size: large;"><b>Return Type</b>: A stored procedure does not have a mandatory return type. It can return zero or more result sets or output parameters. A function has a defined return type and must return a value or a table of values.</span></li><li><span style="font-size: large;"><b>Usage in Queries</b>: A stored procedure can be invoked from within a query or used as a standalone statement. A function is typically used within a query as part of an expression or a select statement.</span></li><li><span style="font-size: large;"><b>Transaction Control</b>: A stored procedure can initiate and control transactions. It can include transaction management statements like BEGIN TRANSACTION, COMMIT, and ROLLBACK. A function cannot initiate or control transactions.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How to use exception handling in functions?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL, exception handling in functions is limited compared to stored procedures. Functions can only handle exceptions related to user-defined errors using the `TRY...CATCH` construct. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">CREATE FUNCTION </span>your_function</span></p><p style="text-align: justify;"><span style="font-size: medium;">(</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;">-- Function parameters</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">)</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">RETURNS </span>data_type</span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;">AS</span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;">BEGIN</span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;"> BEGIN TRY</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> -- Function logic</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">END TRY</span></span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;"> BEGIN CATCH</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> -- Error handling</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">END CATCH</span></span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: large;"> RETURN</span><span style="color: #274e13;"><span style="font-size: large;"> </span><span style="font-size: large;">-- Return statement</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">END</span>;</span></p><p style="text-align: justify;"><span style="font-size: medium;">Within the `BEGIN TRY` block, you can write your function's logic. If an error occurs, the `BEGIN CATCH` block is executed, allowing you to handle the exception appropriately.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How to handle exceptions in stored procedures?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL, stored procedures provide robust exception handling capabilities using the `TRY...CATCH` construct. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">CREATE PROCEDURE</span> your_procedure</span></p><p style="text-align: justify;"><span style="font-size: medium;">(</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> -- Procedure parameters</span></span></p><p style="text-align: justify;"><span style="font-size: medium;">)</span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;">AS</span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;">BEGIN</span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;"> BEGIN TRY</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;">-- Procedure logic</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;"> END TRY</span></span></p><p style="text-align: justify;"><span style="color: #2b00fe; font-size: medium;"> BEGIN CATCH</span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #274e13;"> -- Error handling</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"> <span style="color: #2b00fe;">END CATCH</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">END</span>;</span></p><p style="text-align: justify;"><span style="font-size: medium;">Within the `BEGIN TRY` block, you can write your procedure's logic. If an error occurs, the `BEGIN CATCH` block is executed, allowing you to handle the exception appropriately.</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is a transaction in a stored procedure?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">A transaction in a stored procedure is a logical unit of work that consists of one or more database operations. Transactions ensure that all operations within the unit are treated as a single, indivisible entity. They provide the ACID (Atomicity, Consistency, Isolation, Durability) properties to maintain data integrity and consistency. Transactions can be initiated using the `BEGIN TRANSACTION` statement, and changes made within the transaction can be either committed (`COMMIT`) or rolled back (`</span><span style="font-size: large;">ROLLBACK`) based on the desired outcome.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;">Types of functions in SQL?</span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL, there are several types of functions, including:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>Scalar Functions:</b> Return a single value based on input parameters.</span></li><li><span style="font-size: medium;"><b>Table-Valued Functions:</b> Return a table as a result, allowing multiple rows and columns to be returned.</span></li><li><span style="font-size: medium;"><b>Aggregate Functions:</b> Perform calculations on a set of values and return a single value, such as SUM, AVG, COUNT, MIN, MAX, etc.</span></li><li><span style="font-size: medium;"><b>String Functions:</b> Manipulate and operate on string values, such as CONCAT, SUBSTRING, LEN, etc.</span></li><li><span style="font-size: medium;"><b>Date and Time Functions: </b>Perform operations on date and time values, such as GETDATE, DATEPART, DATEADD, etc.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What are the built-in aggregate functions in SQL Server?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">SQL Server provides several built-in aggregate functions, including:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>SUM</b>: Calculates the sum of a set of values.</span></li><li><span style="font-size: medium;"><b>AVG</b>: Calculates the average of a set of values.</span></li><li><span style="font-size: medium;"><b>COUNT</b>: Counts the number of rows or non-null values in a set.</span></li><li><span style="font-size: medium;"><b>MIN</b>: Retrieves the minimum value from a set.</span></li><li><span style="font-size: medium;"><b>MAX</b>: Retrieves the maximum value from a set.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Built-in string functions in SQL Server?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">SQL Server provides various built-in string functions, including:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>CONCAT</b>: Concatenates two or more strings together.</span></li><li><span style="font-size: medium;"><b>SUBSTRING</b>: Extracts a portion of a string.</span></li><li><span style="font-size: medium;"><b>LEN</b>: Returns the length of a string.</span></li><li><span style="font-size: medium;"><b>UPPER</b>: Converts a string to uppercase.</span></li><li><span style="font-size: medium;"><b>LOWER</b>: Converts a string to lowercase.</span></li><li><span style="font-size: medium;"><b>REPLACE</b>: Replaces occurrences of a specified string with another string.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is SQL Profiler?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">SQL Profiler is a tool provided by Microsoft SQL Server that allows you to monitor and capture events occurring in a SQL Server database. It provides a graphical interface to trace and analyze database activities, including queries, stored procedure executions, errors, and performance-related information. SQL Profiler is useful for debugging, optimizing queries, troubleshooting, and auditing database activities.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How to create an index in SQL Server?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">To create an index in SQL Server, you can use the CREATE INDEX statement. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">CREATE INDEX</span> index_name</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">ON </span>your_table (column1, column2, ...);</span></p><p style="text-align: justify;"><span style="font-size: medium;">Replace `index_name` with the desired name for the index, `your_table` with the name of your table, and `column1`, `column2`, etc., with the columns you want to include in the index. Indexes improve query performance by allowing faster data retrieval based on the indexed columns.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Types of joins in SQL Server?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL Server, the common types of joins are:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>INNER JOIN:</b> Returns rows that have matching values in both tables.</span></li><li><span style="font-size: medium;"><b>LEFT JOIN (or LEFT OUTER JOIN):</b> Returns all rows from the left table and matching rows from the right table.</span></li><li><span style="font-size: medium;"><b>RIGHT JOIN (or RIGHT OUTER JOIN): </b>Returns all rows from the right table and matching rows from the left table.</span></li><li><span style="font-size: medium;"><b>FULL JOIN (or FULL OUTER JOIN):</b> Returns all rows from both tables, with NULL values for non-matching rows.</span></li><li><span style="font-size: medium;"><b>CROSS JOIN:</b> Returns the Cartesian product of both tables (all possible combinations of rows).</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Difference between left outer join and right outer join?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The main difference between a left outer join and a right outer join is the tables from which the non-matching rows are retrieved:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>Left Outer Join:</b> Retrieves all rows from the left (or first) table and the matching rows from the right (or second) table. Non-matching rows from the right table will have NULL values in the result set.</span></li><li><span style="font-size: large;"><b>Right Outer Join:</b> Retrieves all rows from the right (or second) table and the matching rows from the left (or first) table. Non-matching </span><span style="font-size: large;">rows from the left table will have NULL values in the result set.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: large;">The choice between left and right outer join depends on the desired output and the relationship between the tables.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>In what situation do you use a self-join?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">A self-join is used when a table needs to be joined with itself based on a relationship between two columns within the same table. It is commonly used when working with hierarchical data or when you need to compare rows within the same table.</span></p><p style="text-align: justify;"><span style="font-size: large;">For example, consider a table that stores employee information, where each row contains an employee ID and a manager ID that references another employee in the same table. By performing a self-join on the employee ID and manager ID columns, you can retrieve information about employees and their respective managers.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How to improve the performance of an existing stored procedure?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">To improve the performance of an existing stored procedure, you can consider the following approaches:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;">Optimize Query Logic: Review the SQL statements within the stored procedure and ensure they are efficient. Use appropriate indexes, avoid unnecessary joins or subqueries, and optimize WHERE clauses.</span></li><li><span style="font-size: large;">Use Proper Indexing: Analyze the execution plan of the stored procedure and identify missing or inefficient indexes. Create indexes on columns used in join conditions, WHERE clauses, or ORDER BY clauses.</span></li><li><span style="font-size: large;">Minimize Data Retrieval: Retrieve only the necessary columns and rows instead of fetching all data. Use appropriate filtering conditions and limit the result set size.</span></li><li><span style="font-size: large;">Re-evaluate Cursors: If your stored procedure uses cursors, consider alternative approaches like set-based operations to improve performance.</span></li><li><span style="font-size: large;">Regularly Update Statistics: Keep the statistics of the database up to date to ensure the query optimizer has accurate information for generating efficient execution plans.</span></li><li><span style="font-size: large;">Consider Stored Procedure Recompilation: In some cases, forcing a stored procedure to recompile can help improve performance. This can be done using the `WITH RECOMPILE` option.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Types of triggers in SQL?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL, there are two types of triggers:</span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: large;"><b>DML Triggers:</b> These triggers are fired in response to data manipulation language (DML) events, such as INSERT, UPDATE, and DELETE statements on a table.</span></li><li><span style="font-size: large;"><b>DDL Triggers:</b> These triggers are fired in response to data definition language (DDL) events, such as CREATE, ALTER, and DROP statements on a database or table.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: large;">Triggers allow you to define custom actions or validations that are automatically executed when specific events occur.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><b><span style="font-size: x-large;">Which one is faster between stored procedures and functions? How?</span></b></p><p style="text-align: justify;"><span style="font-size: large;">Stored procedures are generally faster than functions because they are precompiled and cached by the database server. When a stored procedure is executed, the execution plan is already compiled, resulting in faster execution.</span></p><p style="text-align: justify;"><span style="font-size: large;">Functions, on the other hand, need to be evaluated for each row or record being processed. This can lead to additional overhead and slower performance, especially when functions are used in queries that involve large datasets.</span></p><p style="text-align: justify;"><span style="font-size: large;">However, it's important to note that the actual performance can vary depending on the specific scenario, the complexity of the logic, the amount of data being processed, and other factors. It's recommended to benchmark and analyze the performance of both stored procedures and functions in your specific environment to determine the optimal choice.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How to create a view?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">To create a view in SQL, you can use the CREATE VIEW statement. Here's an example:</span></p><p style="text-align: justify;"><span style="font-size: large;"><span style="color: #2b00fe;">CREATE VIEW </span>your_view_name <span style="color: #2b00fe;">AS</span></span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">SELECT </span>column1, column2, ...</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">FROM </span>your_table</span></p><p style="text-align: justify;"><span style="font-size: medium;"><span style="color: #2b00fe;">WHERE </span>condition;</span></p><p style="text-align: justify;"><span style="font-size: medium;">Replace `your_view_name` with the desired name for the view, `column1`, `column2`, etc., with the columns you want to include in the view, `your_table` with the name of the table you want to create the view from, and `condition` with any desired filtering</span><span style="font-size: large;"> condition.</span></p><p style="text-align: justify;"><span style="font-size: large;">A view is a virtual table that is based on the result of a SELECT statement. It allows you to simplify complex queries, provide a layer of abstraction, and present a subset of data to users or applications.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><div class="separator" style="clear: both; text-align: justify;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1bSAGQBvgf8V56rYfNlZxjzv1QLTu8paV8BCK78hCyDejbOK9WH-_xnHNPu2OwpOgXNej7cWd3y3UWr_dZtIL_K_wGY_Xx9cwBjWBwmwOJ8xwWiKWAcXlSMMvOrJArItwfnNVBqdnc4j2LQzVPKFY6-ireE_JH2HFWB_SUvYjV7h01x6f0WbC_3zENs8/s2000/White%20And%20Brown%20Simple%20Modern%20Creative%20Stance%20Design%20Presentation%20Folder.png" style="margin-left: 1em; margin-right: 1em;"><img alt="Best Dotnet Training" border="0" data-original-height="2000" data-original-width="1333" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi1bSAGQBvgf8V56rYfNlZxjzv1QLTu8paV8BCK78hCyDejbOK9WH-_xnHNPu2OwpOgXNej7cWd3y3UWr_dZtIL_K_wGY_Xx9cwBjWBwmwOJ8xwWiKWAcXlSMMvOrJArItwfnNVBqdnc4j2LQzVPKFY6-ireE_JH2HFWB_SUvYjV7h01x6f0WbC_3zENs8/w426-h640/White%20And%20Brown%20Simple%20Modern%20Creative%20Stance%20Design%20Presentation%20Folder.png" width="426" /></a></div><br /><p><br /></p>Suthahar Jegatheesanhttp://www.blogger.com/profile/14709587036173890626noreply@blogger.com0tag:blogger.com,1999:blog-5602264950125608941.post-619130608377487962023-06-23T21:53:00.007-07:002023-06-23T22:47:42.776-07:00Apply Freshers Job : Don't Waste Time in Remembering Company Names & Searching their Career Pages - Apply Directly!<div class="separator" style="clear: both; text-align: left;"><span style="font-size: medium;">When searching for job opportunities, it can be quite tedious to remember the names of various companies and then spend time searching for their respective career pages.

It can contain abstract and non-abstract members.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How do you define an abstract class in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An abstract class is defined using the `abstract` keyword before the class declaration. For example: `abstract class MyClass { }`</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class have constructors?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can have constructors. However, they cannot be used to create instances of the abstract class directly.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is an interface in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An interface defines a contract that a class must adhere to. It specifies a set of methods, properties, events, or indexers that a class must implement.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>How do you define an interface in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: large;">An interface is defined using the `interface` keyword. For example: `interface IMyInterface { }`</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can a class inherit multiple interfaces in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, a class can inherit multiple interfaces in C# using the `comma` (,) separator. For example: `class MyClass : IInterface1, IInterface2 { }`</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class implement an interface?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can implement one or more interfaces by providing the implementations for their members.</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class be sealed in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, an abstract class cannot be sealed as it is intended to be inherited by subclasses.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the difference between an abstract class and an interface?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An abstract class can have both abstract and non-abstract members, whereas an interface can only have abstract members. A class can inherit only one abstract class, but it can implement multiple interfaces.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you create an instance of an interface in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, you cannot create an instance of an interface directly. You can only create instances of classes that implement the interface.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the purpose of an abstract method?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An abstract method is a method declaration without an implementation. It is meant to be overridden by the subclasses that derive from the abstract class.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class have non-abstract methods?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can have both abstract and non-abstract methods. Non-abstract methods provide default behavior that can be used by the subclasses.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class inherit from another abstract class in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can inherit from another abstract class. In such a case, the derived class must provide implementations for all abstract members.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class implement an abstract method from an interface?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can implement an abstract method from an interface. The implementing class derived from the abstract class must provide the implementation.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can interfaces have fields in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, interfaces cannot have fields. They can only define properties, methods, events, and indexers.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an interface inherit from another interface?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an interface can inherit from one or more interfaces using the `colon` (:) separator. For example: `interface IMyInterface : IBaseInterface { }`</span></p><p style="text-align: justify;"><span style="font-size: large;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the purpose of an explicit interface implementation?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Explicit interface implementation is used when a class implements multiple interfaces that have members with the same name. It allows disambiguation of the members.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class be used to create objects?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, an abstract class cannot be directly instantiated. You need to create a subclass and instantiate it to create objects.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class contain a constructor with parameters?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can have constructors with parameters. These constructors can be used by derived classes to initialize the abstract class.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class have a private constructor?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can have a private constructor. However, it can only be used by other constructors within the same abstract class.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class have static members?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can have static members such as static fields, properties, methods, and events.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an interface inherit from a class in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, an interface cannot inherit from a class. It can only inherit from other interfaces.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can you implement an interface explicitly and implicitly in the same class?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, a class can implement an interface both explicitly and implicitly. Implicit implementation is used when the class wants to provide a public interface, while explicit implementation is used when the class wants to provide multiple interfaces or handle naming conflicts.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is the difference between a virtual method and an abstract method?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">A virtual method has an implementation in the base class and can be overridden in derived classes, whereas an abstract method has no implementation in the base class and must be overridden in derived classes.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class implement a virtual method?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can implement a virtual method. However, the derived class can still override the virtual method if needed.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class be a sealed class in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, an abstract class cannot be sealed. The purpose of an abstract class is to provide a base for other classes to inherit from.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can a class be both abstract and sealed in C#?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">No, a class cannot be both abstract and sealed. Abstract classes are meant to be inherited, while sealed classes cannot be inherited.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>Can an abstract class have a destructor?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, an abstract class can have a destructor (finalizer) defined using the `~` syntax.

It is designed to perform a specific task or a series of tasks and can be called and executed multiple times.</span></p><p style="text-align: justify;"><span style="font-size: large;"><b>Here are some key characteristics and benefits of stored procedures in SQL Server:</b></span></p><p style="text-align: justify;"><span style="font-size: large;">1.<b> Modularity and Code Reusability:</b> Stored procedures promote modular programming by encapsulating SQL logic into a single unit. This allows for code reusability, as the same stored procedure can be called from multiple applications or parts of the database.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;">2. <b>Performance Optimization:</b> Stored procedures are compiled and stored in a compiled format in the database, which enhances performance by reducing the need for repetitive parsing and optimization of SQL statements. This can result in faster execution times compared to ad hoc queries.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;">3. <b>Security and Access Control:</b> Stored procedures provide a level of security by allowing control over who can execute them and the permissions required to access the underlying data. This helps in enforcing security policies and preventing unauthorized access to data.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;">4. <b>Transaction Management:</b> Stored procedures can be used to define and manage transactions, ensuring data integrity and consistency. They allow for explicit transaction control using `BEGIN TRANSACTION`, `COMMIT`, and `ROLLBACK` statements.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;">5. <b>Parameterized Execution:</b> Stored procedures support input and output parameters, allowing for flexible and parameterized execution. Parameters can be used to pass values into the stored procedure and retrieve results or output values.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;">6. <b>Code Encapsulation and Maintenance:</b> By storing SQL logic and procedural code in a stored procedure, you can separate it from the application code. This makes it easier to maintain and modify the database logic independently from the application logic.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;">7. <b>Reduced Network Traffic:</b> By executing a stored procedure on the server side, only the results or relevant data are transmitted over the network, reducing network traffic compared to sending multiple individual SQL statements.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: medium;">8. <b>Version Control and Consistency:</b> Stored procedures can be version-controlled, ensuring consistency in the execution of database logic across different environments and deployments.</span></p><p style="text-align: justify;"><span style="font-size: large;">Overall, stored procedures in SQL Server provide a powerful tool for managing and organizing database logic, improving performance, enhancing security, and promoting code reusability.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: x-large;"><b>What is a stored procedure?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"> A stored

title="Interview questions and answers for WPF MVVM" width="640" /></a></b></span></div><span style="font-size: x-large;"><b><br /></b><b>What is MVVM (Model-View-ViewModel) and how does it differ from other architectural patterns?</b></span><p></p><p style="text-align: justify;"><span style="font-size: medium;">MVVM is an architectural pattern that separates the application into three components: Model, View, and ViewModel. It allows for better separation of concerns, promotes reusability, and facilitates unit testing. Unlike other patterns, MVVM focuses on data binding and the use of commands to handle user interactions.</span></p><p><br /></p><p><span style="font-size: x-large;"><b>What are the key components of the MVVM pattern?</b></span></p><p></p><ul style="text-align: left;"><li style="text-align: justify;"><span style="font-size: medium;">Model: Represents the data and business logic of the application.</span></li><li style="text-align: justify;"><span style="font-size: medium;">View: Represents the UI elements and defines the visual layout.</span></li><li style="text-align: justify;"><span style="font-size: medium;">ViewModel: Acts as a bridge between the Model and View, providing data and behavior for the View. It also implements commands for user interactions.</span></li></ul><p></p><p><br /></p><p><span style="font-size: x-large;"><b>What is data binding in WPF MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Data binding is a mechanism in WPF MVVM that establishes a connection between the properties of the ViewModel and the UI elements in the View. It allows for automatic synchronization of data between the ViewModel and the View, eliminating the need for manual updates.</span></p><p><br /></p><p><span style="font-size: x-large;"><b>How do you handle property changes in the ViewModel?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In the ViewModel, implement the INotifyPropertyChanged interface and raise the PropertyChanged event whenever a property value changes. This notifies the View that a property has been updated, and the View can update the corresponding UI elements.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>What is ICommand and how is it used in MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">ICommand is an interface that defines a command, typically used for handling user interactions in MVVM. It provides methods for checking if the command can be executed and for executing the command itself. By binding UI elements to ICommand properties in the ViewModel, you can invoke specific actions or methods.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>How do you handle collections in the ViewModel using MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In the ViewModel, use ObservableCollection<T> to represent collections that can be dynamically updated. ObservableCollection<T> implements the INotifyCollectionChanged interface, which notifies the View when items are added, removed, or modified in the collection. This ensures that the UI stays synchronized with the underlying collection.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>How do you perform navigation between views in MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Navigation between views in MVVM can be achieved using a navigation service or a view service. The navigation service handles the logic of transitioning between views while keeping the separation between the ViewModel and the View. The navigation service may use techniques like view mapping or URI-based navigation to navigate to different views.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>How do you perform validation in MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">MVVM provides several ways to perform validation. You can use data annotations in the Model or ViewModel to specify validation rules. Additionally, you can implement the IDataErrorInfo interface in the ViewModel to provide custom validation logic. The View can then display validation error messages based on the validation rules defined in the ViewModel.</span></p><p><br /></p><p><span style="font-size: x-large;"><b>How do you bind a property in the ViewModel to a UI element in XAML?</b></span></p><p><span style="color: #274e13;

It allows you to bind UI elements to commands in the ViewModel and handle user interactions. RelayCommand provides a simple way to encapsulate the action logic that needs to be executed when a command is invoked.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>How do you implement two-way data binding in WPF MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Two-way data binding allows changes in the UI to automatically update the corresponding ViewModel property and vice versa. To implement two-way data binding, set the `Mode` property of the binding to `TwoWay`. For example:</span></p><p><span style="color: #274e13; font-size: medium;"><!-- View.xaml --></span></p><p><span style="font-size: medium;"><TextBox <span style="color: #45818e;">Text</span>="{<span style="color: #7f6000;">Binding</span> <span style="color: #783f04;">UserName</span>, <span style="color: #45818e;">Mode</span>=<span style="color: #7f6000;">TwoWay</span>}" /></span></p><p><br /></p><p><span style="font-size: x-large;"><b>How do you handle exceptions in MVVM when using async/await?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">When using async/await in MVVM, you can handle exceptions by adding a try-catch block around the asynchronous operation or by using the `Task.Run` method. In the catch block, you can display an error message or perform appropriate error handling based on the exception that occurred.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>What is the purpose of the INotifyPropertyChanged interface in MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The INotifyPropertyChanged interface is used to notify the View when a property in the ViewModel has changed. It defines the `PropertyChanged` event, which the ViewModel raises whenever a property value is updated. This allows the View to update the corresponding UI elements and keep them synchronized with the ViewModel.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>How do you handle multiple views sharing the same ViewModel in MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">To have multiple views sharing the same ViewModel, you can create a single instance of the ViewModel and bind it to the DataContext of each view. This ensures that all views interact with the same instance of the ViewModel, allowing them to share data and maintain consistency.</span></p><p style="text-align: justify;"><br /></p><p><span style="font-size: x-large;"><b>What are the advantages of using MVVM in WPF applications?</b></span></p><p></p><ul style="text-align: left;"><li><span style="font-size: medium;">MVVM provides better separation of concerns, allowing for easier maintenance and testability of the codebase.</span></li><li><span style="font-size: medium;">It promotes code reusability by decoupling the UI from the business logic and data.</span></li><li><span style="font-size: medium;">MVVM facilitates unit testing of the ViewModel independent of the UI.</span></li><li><span style="font-size: medium;">It enables more efficient collaboration between designers and developers by separating the design and development tasks.</span></li></ul><p></p><p><br /></p><p><span style="font-size: x-large;"><b>How do you implement dependency injection in MVVM?</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Dependency injection can be implemented in MVVM by using an IoC (Inversion of Control) container. The container manages the creation and lifetime of objects and resolves dependencies. It allows you to inject dependencies into the ViewModel, making it easier to test and decoupling it from specific implementations.</span></p><p style="text-align: justify;"><br /></p><p><br /></p>Suthahar Jegatheesanhttp://www.blogger.com/profile/14709587036173890626noreply@blogger.com0tag:blogger.com,1999:blog-5602264950125608941.post-83317592017866367672023-06-12T20:04:00.002-07:002023-06-12T20:04:17.150-07:00Top 40 Microsoft SQL database functions<p><span style="font-size: medium;"><br /></span></p><p><span style="font-size: x-large;"><b>1.

Garbage Collector in C#:</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"> The garbage collector in C# is a part of the .NET runtime that automatically manages memory by reclaiming memory occupied by objects that are no longer in use. It tracks object references, identifies unused objects, and frees up memory for future allocations.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>2. CLR (Common Language Runtime): </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">CLR is the execution environment in the .NET framework that provides various services such as memory management, exception handling, security, and code execution. It compiles and manages code written in different .NET languages into a common intermediate language (CIL) and executes it.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>3. Difference between String and StringBuilder: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In C#, a String is an immutable sequence of characters, meaning it cannot be modified once created. StringBuilder, on the other hand, is a mutable class that allows efficient modification of strings by appending, inserting, or replacing characters without creating new instances.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>4. Enum Keyword: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The enum keyword in C# is used to declare an enumeration, which is a distinct type representing a set of named constants. It provides a way to define a group of related values that can be assigned to a variable, improving code readability and maintainability.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>5. Enum Value Types: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, enum values in C# are value types. Each enumerated value represents a named constant of the enum type, and they are internally represented as integer values.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>6. Managed Code and Unmanaged Code:</b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Managed code refers to code that runs within the managed environment of the CLR. It is written in languages such as C# or VB.NET and benefits from automatic memory management, security enforcement, and exception handling. Unmanaged code, on the other hand, is typically written in languages like C or C++ and runs outside the CLR's control, without the same level of automatic memory management and other managed code benefits.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>7. Difference between Generic and Non-Generic: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In C#, generics provide a way to create reusable, type-safe code that works with multiple data types. Generic classes, methods, and interfaces can be parameterized with specific types, allowing for greater flexibility and code reusability. Non-generic counterparts, on the other hand, are not type-safe and typically operate on a specific data type without the flexibility of working with different types.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>8. Namespace for Generic: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The System.Collections.Generic namespace in C# contains classes and interfaces for generic collections, such as List<T>, Dictionary<TKey, TValue>, etc.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>9. Namespace for Non-Generic: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The System.Collections namespace in C# contains classes and interfaces for non-generic collections, such as ArrayList, Hashtable, etc.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>10. Example for Generic: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An example of a generic class in C# is List<T>. It allows you to create a list that can hold elements of any specific type, such as List<int>, List<string>, List<Person>, etc.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>11. Difference between Dictionary and DataTable:</b></span><span style="font-size: medium;"> </span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">Dictionary is a generic collection that stores key-value pairs, allowing efficient lookup of values based on keys. It is typically used when you need fast access to elements based on unique keys.</span></li><li><span style="font-size: large;">DataTable, on the other hand, is a tabular representation of data that can hold multiple rows and columns. It is commonly used for storing and manipulating structured data, similar to a database table.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>12. Difference between Function Overloading and Function Overriding:</b></span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">Function Overloading: Function overloading in C# allows multiple methods in a class to have the same name but with different parameters. The compiler distinguishes between the overloaded methods based on the number, types, and order of the parameters.</span></li><li><span style="font-size: medium;">Function Overriding: Function overriding occurs in inheritance when a derived class provides its own implementation of a method that is already defined in its base class. The overridden method in the derived class should have the same signature as the base class method.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>13. Two Keywords for Function Overriding: The two keywords</b></span></p><p style="text-align: justify;"><span style="font-size: large;">used for function overriding in C# are "override" and "virtual". The base class method that can be overridden is marked with the "virtual" keyword, and the derived class method that overrides it is marked with the "override" keyword.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>14. Use of "using" Keyword in C#: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The "using" keyword in C# is used to define a scope within which a specific resource is used. It ensures that the resource is properly disposed of, even if an exception occurs, by implementing the IDisposable interface. It is commonly used with objects that access external resources, such as database connections or file streams.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>15. Difference between Array and ArrayList:</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Array:</b> In C#, an array is a fixed-size collection of elements of the same type. The size of an array is determined at the time of its creation and cannot be changed. Arrays provide fast access to elements by their index.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>ArrayList:</b> ArrayList is a non-generic collection in C# that can dynamically grow or shrink in size. It can hold elements of different types and provides methods for adding, removing, and accessing elements. However, it is slower compared to arrays due to boxing and unboxing operations.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>16. Difference between "is" and "as" Keyword: </b></span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">"is" keyword in C# is used for type checking. It checks if an object is of a specified type and returns a boolean value (true or false).</span></li><li><span style="font-size: medium;">"as" keyword in C# is used for type casting. It attempts to cast an object to a specified type. If the cast is successful, it returns the cast object; otherwise, it returns null.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>17. Extension Method: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">An extension method in C# allows you to add new methods to existing types without modifying their original implementation or creating a new derived type. It is defined as a static method in a static class and must be in the same namespace as the extended type. Extension methods are called as if they were instance methods of the extended type.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>18. Sealed Class: </b></span></p><p></p><ul style="text-align: left;"><li style="text-align: justify;"><span style="font-size: medium;">A sealed class in C# is a class that cannot be inherited.</span></li><li style="text-align: justify;"><span style="font-size: medium;"> It is marked with the "sealed" keyword.</span></li><li style="text-align: justify;"><span style="font-size: medium;">Sealing a class prevents it from being used as a base class for other classes.</span></li><li style="text-align: justify;"><span style="font-size: medium;"> Sealed classes are used when you want to restrict further inheritance and maintain the integrity of the class's implementation.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: large;"><b>19. Multiple Try-Catch Blocks in C#: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">Yes, it is possible to use multiple try-catch blocks in C#. Each try block can be followed by one or more catch blocks that handle specific types of exceptions. This allows you to handle different exceptions separately and perform specific actions based on the exception type.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>20. Difference between "==" Operator and "Equals" Method in C#: </b></span></p><p style="text-align: justify;"></p><ul><li><span style="font-size: medium;">The "==" operator in C# is used for equality comparison between two variables. For value types, it compares the actual values, while for reference types, it compares the references (memory addresses) of the objects.</span></li><li><span style="font-size: medium;">The "Equals" method in C# is a method defined in the Object class that can be overridden in derived classes. It is used to compare the equality of two objects based on their values or properties. The behavior of the "Equals" method can be customized based on the class's implementation.</span></li></ul><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>21. Access Modifiers in C#: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The access modifiers in C# determine the accessibility or visibility of types and members (fields, methods, properties, etc.). The main access modifiers are:</span></p><p></p><ol style="text-align: left;"><li style="text-align: justify;"><span style="font-size: medium;">public: The type or member is accessible from any code.</span></li><li style="text-align: justify;"><span style="font-size: medium;">private: The type or member is accessible only within the containing class.</span></li><li style="text-align: justify;"><span style="font-size: medium;">protected: The type or member is accessible within the containing class and its derived classes.</span></li><li style="text-align: justify;"><span style="font-size: medium;">internal: The type or member is accessible within the same assembly (project or DLL).</span></li><li style="text-align: justify;"><span style="font-size: medium;"> protected internal: The type or member is accessible within the same assembly and its derived classes, both inside and outside the assembly.</span></li></ol><p></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>22. Use of "FirstOrDefault"</b></span></p><p style="text-align: justify;"><span style="font-size: large;">In LINQ: The "FirstOrDefault" method in LINQ is used to retrieve the first element of a sequence that satisfies a specified condition. If no element matches the condition, it returns the default value for the type, such as null for reference types or 0 for numeric types. It is commonly used to avoid null reference exceptions when accessing the first element of a sequence.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>23. Default Database in SQL Server: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">The default database in SQL Server refers to the initial database that is used when a user connects to the SQL Server instance. The default database can be specified for each user, and it determines the database where the user's queries and operations are performed by default.</span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL Server, the default databases that are commonly available include:</span></p><p></p><ol style="text-align: left;"><li style="text-align: justify;"><span style="font-size: medium;"> master: The master database stores system-level information and configuration settings. It records information about all other databases and is crucial for the functioning of the SQL Server instance.</span></li><li style="text-align: justify;"><span style="font-size: medium;">tempdb: The tempdb database is used to store temporary objects such as temporary tables, global temporary tables, and temporary stored procedures. It is recreated every time SQL Server starts.</span></li><li style="text-align: justify;"><span style="font-size: medium;">model: The model database serves as a template for creating new databases. When a new database is created, it is initialized with the contents of the model database.</span></li><li style="text-align: justify;"><span style="font-size: medium;"> msdb: The msdb database stores information related to SQL Server Agent, including jobs, alerts, operators, and backup and restore history. It is used for managing scheduling, maintenance plans, and other administrative tasks.</span></li></ol><p><span style="font-size: medium;"></span></p><p style="text-align: justify;"><span style="font-size: medium;">These are the default databases commonly found in SQL Server installations. However, it's worth noting that additional user-defined databases can be created as per specific requirements.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>24. Primary Key in SQL: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL, a primary key is a column or a set of columns that uniquely identifies each row in a table. It ensures the uniqueness and integrity of the data in the table. The primary key constraint enforces the uniqueness and non-nullability of the specified column(s).</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>25. Difference between Primary Key and Foreign Key:</b></span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Primary Key:</b> A primary key is a column or a set of columns in a table that uniquely identifies each row. It ensures the uniqueness and integrity of the data within the table.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><b>Foreign Key:</b> A foreign key is a column or a set of columns in a table that establishes a relationship with the primary key of another table. It creates referential integrity between two tables and enforces data consistency and integrity across the tables.</span></p><p style="text-align: justify;"><span style="font-size: medium;"><br /></span></p><p style="text-align: justify;"><span style="font-size: large;"><b>26. Use of Null Value in Primary Key: </b></span></p><p style="text-align: justify;"><span style="font-size: medium;">In SQL, a primary key column cannot contain a null value. It must have a unique and non-null value for each row, as it is used to identify each record uniquely.</span></p>Suthahar Jegatheesanhttp://www.blogger.com/profile/14709587036173890626noreply@blogger.com0
