Interfaces
In C#, an interface is a reference type that defines a contract for other classes to implement. It allows you to define a set of methods, properties, and events that a class must implement. An interface only contains method signatures, properties, and event declarations, without any implementations.
Interfaces play a crucial role in achieving multiple inheritance in C#. C# classes can implement multiple interfaces, which allows them to inherit the behavior of multiple interfaces.
Here's an example of using interfaces in C#:
