The important purpose of poly polymorphism is implementation on different programming languages. The programmer (and the program) does not have to know the exact type of the object in advance, and so the exact behavior is determined at run-time is also called dynamic binding. And different objects involved only need to present a compatible interface to the clients' .That is, there must be public or internal methods, fields, events, and properties with the same name and the same parameter sets in all the superclasses, subclasses and interfaces. In principle, the object types may be unrelated, but since they share a common interface, they are often implemented as subclasses of the same super class. Though it is not required, it is understood that the different methods will also produce similar results.
