Polymorphism

Polymorphism is another fundamental concept of Object-Oriented Programming (OOP) and is supported in C#. Polymorphism allows objects of different classes to be treated as objects of the same type. This enables you to write code that can handle objects of different classes using a common interface.

There are two main forms of polymorphism in C#: method overriding and method overloading.

Method Overriding

Method overriding allows a derived class to provide its own implementation of a method that it inherits from its base class. When an object of the derived class is created, the method in the derived class is invoked instead of the method in the base class.

Here is an example of method overriding in C#:

In this example, the StartEngine method in the SportsCar class overrides the same method in the Car class. When an object of the SportsCar class is created, calling StartEngine will invoke the override method in the derived class.

Method Overloading

Method overloading allows multiple methods with the same name but different parameters to be defined in the same class. When an object of the class is created, the appropriate method is invoked based on the parameters passed to it.

Here is an example of method overloading in C#:

In this example, the Accelerate method is overloaded with two different sets of parameters. When an object of the Car class is created, calling Accelerate with either one or two parameters will invoke the appropriate method.

Polymorphism allows you to write code that is flexible and adaptable to changes. With polymorphism, you can write code that can handle objects of different classes using a common interface, making your code more organized and reusable.
