Answer / radhika

An interface defines a contract for a class.The name of an
interface begins with a capital I.interface doesnot
contains any method implementations.The class that
implements the interface must provide all the
implementation for the members defined in that interface.

Answer / mohit bhandari

An interface is a named set of method signatures.Interfaces
can also define events and properties because all of these
are just syntax shorthands that map to methods anyway.
In C#, interface keyword is used to define an interface,
giving it a name and its set of instance method signatures.
e.g.
public interface IDisposable {
void Dispose();
}
