What are the types of Polymorphism?

There are two types of Polymorphism:

i. Static or compile-time polymorphism

ii. Dynamic or runtime polymorphism

In .NET, polymorphism can be achieved through different mechanisms, primarily:

1. Compile-time Polymorphism (Static Binding or Early Binding):
   • Method Overloading: This involves defining multiple methods in the same class with the same name but different parameters.
   • Operator Overloading: Allows operators like +, -, *, etc., to be overloaded so that they can be used with user-defined types.
2. Runtime Polymorphism (Dynamic Binding or Late Binding):
   • Method Overriding: Inheritance enables a derived class to provide a specific implementation of a method that is already defined in its base class. This is achieved using the virtual and override keywords.
   • Interface Implementation: Implementing interfaces allows objects of different classes to be treated as objects of a common interface, enabling polymorphic behavior.
   • Abstract Classes: Abstract classes can have abstract methods that must be implemented by derived classes, allowing polymorphism through method overriding.

So, for the interview question, you can mention these types of polymorphism, highlighting the distinction between compile-time (static) and runtime (dynamic) polymorphism, along with examples for each type.
