When and how can i use the interface in the C# code? If you want to achieve run time polymorphism and to create loosly coupled components at that time you can go with the interface. what is the utility of interface? I'm not sure what you meant by utility. Did you meant purpose or use of the interface if so you can get the answer in the above lines itself. Let me know if you need any thing more.

Hi An interface looks like a class but has got no implementation. In an interface we cannot do any implementation but we can declare signatures of properties methods delegates and events.
