What are some examples of interfaces in C#?

In C#, interfaces are contracts that define methods and properties without implementing them. Examples include IComparable, IDisposable, and custom interfaces like IAnimal.

Can you explain the IDisposable interface?

Sure! The IDisposable interface provides a mechanism for releasing unmanaged resources. It has a single method, Dispose(), which is called to clean up resources.

How do I implement a custom interface?

To implement a custom interface, define the interface using the interface keyword, then implement it in a class by providing the method definitions.

What is the difference between an interface and an abstract class?

An interface defines a contract without any implementation, while an abstract class can provide some implementation and state. A class can implement multiple interfaces but can inherit from only one abstract class.
