Answer 1

Answer to question #38429, Programming, C#

Defining an Interface:

interface IMyInterface
{
    void someMethodToImplement();
}

Benefits of using interface:

1. The interface essentially guarantees that all the methods that inherit it will have its methods, so that you can safely call a method in the interface for anything that inherits it.

2. An interface allows you to guarantee that certain methods exist and return the required types.

3. Interface usually encapsulates the smallest amount of logic possible to perform related actions.
