C# – an example to illustrate Mutiple Inheritance through interfaces

January 19, 2012

A new year and a new post. Some of the readers might find me coding in C# and Python depending on my mood. Here is an example to show how to use interfaces in your C# program. This also shows multiple inheritance that can be achieved through interfaces.

using System;

interface GetSum
    int GetSum();
interface CalcSum
    void CalcSum(int x,int y);

namespace MultiInterface
    class Addition : GetSum, CalcSum
        int sum;
        public int GetSum()
            return sum;
        public void CalcSum(int x, int y)
            sum = x + y;

    class Program
        static void Main()
            Addition objAdd = new Addition();

            Console.WriteLine("The Sum is = {0}", objAdd.GetSum());


The Sum is = 8200

  1. Great article on C# inheritance. Another good article I have found is C# Inheritance and Polymorphism
