A partial class in C# is a class whose definition can be split across multiple files. This allows for better organization of code, especially in large projects. All parts of the partial class are combined into a single class when the application is compiled. Partial classes are useful for separating different aspects of a class, […]

An interface in C# is a contract that defines a set of methods and properties that a class must implement. It does not contain any implementation itself, only the signatures. Interfaces are used to specify what a class must do, but not how it does it, allowing for flexible and decoupled code design.

Finalize Method: Used for cleanup before garbage collection. Called by the garbage collector. Unreliable for timely cleanup. finally Block: Used in exception handling to ensure cleanup code runs. Always executed after try/catch blocks. Ensures deterministic cleanup. Finalize Method: A method in C# used to perform cleanup operations before an object is reclaimed by garbage collection. […]

An abstract class in C# is a class that cannot be instantiated directly and is designed to be a base class for other classes. It can contain abstract methods (methods without a body) that must be implemented by derived classes, as well as concrete methods with implementation. Abstract classes are used to provide a common […]

Managed Code refers to code that runs under the management of a runtime environment, such as the Common Language Runtime (CLR) in .NET. The CLR handles various aspects of execution, including memory management (garbage collection), security, exception handling, and cross-language integration. Examples include C# and VB.NET code. Unmanaged Code refers to code that runs directly […]

C# features include: Object-Oriented: Supports principles like inheritance, encapsulation, and polymorphism. Type-Safe: Prevents type errors by ensuring that data types are used correctly. Automatic Memory Management: Utilizes garbage collection to manage memory allocation and deallocation. Rich Library: Access to extensive .NET libraries for various functionalities. LINQ (Language Integrated Query): Provides a powerful syntax for querying […]

We use C# because it is a versatile, object-oriented language that is easy to learn and use. It provides strong type safety, automatic garbage collection, and rich library support. C# is commonly used for developing Windows applications, web applications, games (with Unity), and enterprise software due to its robust framework and integration with the .NET […]

Mention all the advantages of C#.

Name all the C# access modifiers.

In C#, there are several ways to pass parameters to a method: By value (default): Passes a copy of the parameter’s value to the method. Changes to the parameter value inside the method do not affect the original value. By reference using ref: Allows the method to modify the value of the parameter directly. The […]
