Abstraction

Abstraction is another fundamental concept of Object-Oriented Programming (OOP) and is supported in C#. Abstraction allows you to create classes that encapsulate implementation details and provide a simplified, higher-level view of the code. This enables you to write code that is easier to understand and maintain.

There are two main ways to achieve abstraction in C#: abstract classes and interfaces.

Abstract Classes

Abstract classes are classes that cannot be instantiated on their own. Instead, they are meant to be inherited by other classes. An abstract class can contain abstract methods, which are methods that have no implementation and must be overridden by derived classes.

Here is an example of an abstract class in C#:

In this example, the Vehicle class is abstract and contains two abstract methods, StartEngine and StopEngine. The Car class inherits from Vehicle and provides concrete implementations of the abstract methods.

Interfaces

Interfaces are similar to abstract classes, but they contain only abstract methods and properties and no implementation. An interface defines a contract that classes must adhere to, but it does not provide any implementation details.

Here is an example of an interface in C#:

In this example, the IVehicle interface defines two methods, StartEngine and StopEngine. The Car class implements the IVehicle interface and provides concrete implementations of the methods.

Abstraction is a powerful tool for writing organized and maintainable code. By encapsulating implementation details and providing a simplified, higher-level view of the code, you can make your code easier to understand and maintain.
