Program to overload binary '*' operator in C#

Here, we will create a sample class with data member X. Assign value using Set() method and print data member value using printValue() method.

using System;
using System.Collections;

namespace ConsoleApplication1
{
    class Sample
    {
        private int X;
        
        public Sample()
        {
            X = 0;
        }

        public void Set(int v)
        {
            X = v;
        }
        public static Sample operator *(Sample S1, Sample S2)
        {
            Sample temp = new Sample();

            temp.X = S1.X * S2.X;
           
            return temp;
        }

        public void printValue()
        {
            Console.WriteLine("Value : {0}", X);
        }
    }

    class Program
    {
        static void Main()
        {
            Sample S1 = new Sample();            
            Sample S2 = new Sample();
            Sample S3 = new Sample();

            S1.Set(30);
            S2.Set(20);

            S3 = S1 * S2;

            S1.printValue();
            S2.printValue();
            S3.printValue();
        }
    }
}

Output

Value : 30
Value : 20
Value : 600

In this program we created two object of class sample S1, S2 and S3. Then multiply value of S1 and S2 and assigned to S3.
