what is Inheritance in C#

Inheritance

Acquiring the properties of an existing class into a new class by establishing a parent–child relationship between classes is known as Inheritance.

The big advantage of inheritance is reusability of code:

using System;  

using System.Collections.Generic;  

using System.Linq;  

using System.Text;  

using System.Threading.Tasks;  

  

namespace InheritanceDemo  

{  

    class Parent  

    {  

        public void ParentMethod()  

        {  

            Console.WriteLine("this is parent method");  

        }  

    }  

    class child :Parent  

    {   

        public void childmethod()  

        {  

            Console.WriteLine("this is child method");  

        }  

        static void Main(string[] args)  

        {        

            child obj = new child();                            

            obj.childmethod();  

            obj.ParentMethod();  

            Console.ReadKey();  

        }  

    }  

}
