polymorphism in c#

by

Polymorphism in C#-: Polymorphism is one of the major benefits of inheritance. With polymorphism, the correct function call is decided at run time based on the derived type of a base reference. This is called late binding and is accomplished by casting instances of related types back to a common base class reference. The common … Read more
