Interface in C# | Interface in CSharp with Examples
In this video, I am going to discuss one of the most important concepts i.e. Interface in C# with Examples. At the end of this session, I am sure, you will understand what is Interface, why we need an interface, and how to use an interface in C# with Examples.
What is an Interface in C#?
The Interface in C# is a fully un-implemented class used for declaring a set of operations of an object. So, we can define an interface as a pure abstract class which allows us to define only abstract methods. The abstract method means a method without a body or implementation. It is used to achieve multiple inheritances which can’t be achieved by class. It is used to achieve full abstraction because it cannot have a method body.
Till now we are learning classes. So, what is a class? A class is a user-defined data type. Then what is an interface? An interface is also a user-defined data type. Then what is the difference between them? Let us understand this first.
Differences between Class, Abstract Class, and Interface in C#:
A class can contain only the methods which contain the method body. Do we have a method without the body? Yes, we have methods without a body and that is called abstract methods. So, simply we can say class contains a method with a method body or you can say non-abstract methods. Abstract class contains both abstract and non-abstract methods and interface contains only abstract methods.
1. Class: Contains only the Non-Abstract Methods (Methods with Method Body).
2. Abstract Class: Contains both Non-Abstract Methods (Methods with Method Body) and Abstract Methods (Methods without Method Body).
3. Interface: Contain only Abstract Methods (Methods without Method Body).
