Answer / srinivas
1. function overloading,
2. Runtime polymorphism --Using Interface reference,
EX:
interface name I ,abstract Method();
implimenting classes A,B
ref I;
objA= new A();
objB= new B();
runtime
objA=I
objA.Method();
objB=I;
objB.Method();

polimorphism is the one of the oops features, allows one
object to appear in different form by changing the type.

1- Static eg:method overloading
2- Dynamic eg:method overriding

Polymorphism is also achieved through interfaces. Like abstract classes, interfaces also describe the methods that a class needs to implement. The difference between abstract classes and interfaces is that abstract classes always act as a base class of the related classes in the class hierarchy. For example, consider a hierarchy-car and truck classes derived from four-wheeler class; the classes two-wheeler and four-wheeler derived from an abstract class vehicle. So, the class 'vehicle' is the base class in the class hierarchy. On the other hand dissimilar classes can implement one interface. For example, there is an interface that compares two objects. This interface can be implemented by the classes like box, person and string, which are unrelated to each other.
C# allows multiple interface inheritance. It means that a class can implement more than one interface. The methods declared in an interface are implicitly abstract. If a class implements an interface, it becomes mandatory for the class to override all the methods declared in the interface, otherwise the derived class would become abstract.
