C# Method Overriding

If derived class defines same method as defined in its base class, it is known as method overriding in C#. It is used to achieve runtime polymorphism. It enables you to provide specific implementation of the method which is already provided by its base class.

To perform method overriding in C#, you need to use virtual keyword with base class method and override keyword with derived class method.

C# Method Overriding Example

Let's see a simple example of method overriding in C#. In this example, we are overriding the eat() method by the help of override keyword.

1. using System;  
2. public class Animal{  
3.     public virtual void eat(){  
4.         Console.WriteLine("Eating...");  
5.     }  
6. }  
7. public class Dog: Animal  
8. {  
9.     public override void eat()  
10.     {  
11.         Console.WriteLine("Eating bread...");  
12.     }  
13. }  
14. public class TestOverriding  
15. {  
16.     public static void Main()  
17.     {  
18.         Dog d = new Dog();  
19.         d.eat();  
20.     }  
21. }  

Output:

Eating bread...
