An interface in C# defines a contract. It is a blueprint of a class, and any class or struct implementing that contract has to offer an implementation of the objects and attributes defined in the interface. All the methods declared inside the interface are the abstract method and thus make an abstract class. It cannot have a method body and can’t be initiated but used to achieve multiple inheritances that cannot be otherwise achieved by class.

In the C# programming language, static is used as a keyword. It is used both with variables and functions, that is if the programmer wants to declare static variables and static functions.
