Inheritance and Polymorphism

Inheritance and Polymorphism

Inheritance and polymorphism are important concepts in object-oriented programming that are used to create more efficient, reusable and flexible code.

Inheritance allows one class to inherit the properties and methods of another class, called the base or parent class. This helps in reducing code duplication and promoting code reusability. In C#, inheritance is achieved using the “class” keyword followed by a colon and the name of the base class.

Polymorphism, on the other hand, allows objects of different classes to be treated as if they belong to a common superclass. This means that a single method can be implemented to handle multiple object types. Polymorphism can be achieved in C# through method overloading and method overriding.

Method overloading is when multiple methods with the same name but different parameters are defined in the same class, while method overriding is when a method in the subclass has the same name, return type, and parameter list as a method in the superclass.

By utilizing inheritance and polymorphism, C# programmers can create code that is more modular, flexible and easier to maintain.
