Easy Guide to Method Overriding in C#

Method Overriding in C#

When one class inherit from another class ,all the member of parent class become the member of child class .If there is a method of parent class that we want to predefined in child class. we can implement the concept of method overriding ,it means a method overriding of parents class and child class can have same method name with same parameter but parent class method will have "VIRTUAL"Keyword and child class method have "OVERRIDE"Keyword.


EXAMPLE:-

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

using System; namespace methodoverriding {     class Program     {         static void Main(string[] args)         {             employee obj = new employee();             obj.display();             Console.ReadLine();         }     } public class cls {     public virtual void display()     {         Console.WriteLine("hello");     } } public class employee : cls {     public override void display()     {         Console.WriteLine("welcome");     } } }

Description:- Here ,I have maked the object of employee class. The display method of only employee class will get in memory,because the "display method" of cls  class has been over-hidden by the employee class.
