We Can Implement Polymorphism In C # Through Method Overloading and Method

Overriding

Method Overloading & Method Overriding

Public class Drawing Object{ public void Draw(){Console .Write Line(“ I’m just

a generic drawing object.”);}}

POLYMORPHISM

Shows the drawing object class this will be the base class for other objects to inherit from ,It has a single method named Draw() .the Draw Method has a virtual Modifier .This virtual Modifier indicates to derived classes that they can override this method

Public class Line: Drawing Object{ public override void Draw(){Console .Write Line(“ I’m a

Line.”);}}Public class Circle : Drawing

Object{public override void Draw(){Console .Write Line (“ I’m a

Circle .”);

An abstract class can implement methods

An abstract class can contain fields

An abstract class can contain constructors or destructors

An interface cannot implement methods

An interface can inherit from another class

An interface can contain signature

ABSTRACT CLASS & INTERFACE

05/02/2023 7

An abstract class cannot be inherited from by a class .

Abstract class cannot support multiple inheritances

Interface cannot contain constructors or destructors

Interface can

support multiple inheritances

ABSTRACT CLASS & INTERFACE

An interface look like a class but has no implementation.The only things that they contain are only signature of methods events and or properties .the reason interface only provide declarations is because they are inherit by classes and which provide implementation for each interface member declared

INTERFACE

An Abstract class has no implementation like interface . Implementation of methods can be use by the child class

ABSTRACT CLASS
