C# Programming/Interfaces. An INTERFACE in C# is a type definition similar to a class, except that it purely represents a contract between an object and its user. It can neither be directly instantiated as an object, nor can data members be defined. So, an interface is nothing but a collection of method and property declarations.
A class can extend one other class and implement any number of interfaces. An interface can extend any number of interfaces. When a class implements an interface it implements all of the methods declared in that interface. You can have variables and parameters of an interface type. method in Java that has a parameter of interface type is nearly the same as a function template in C++. A class that uses interfaces to type any variables or parameters behaves very similarly to a class template in C++. Just think of the interface names as if they were template arguments.
