C# program to overload Equal To (==) and Not Equal To (!=) operators

In this C# program, we are going to learn to overload relational operators like Equal To (==) and Not Equal To (!=). Here is an example with the output.

If we overload Equal To (==) operator then we must overload Not Equal To (!=) operator. Here, in this program, we will create a sample class with data member X. Assign value using Set() method.

Program to overload Equal To (==) and Not Equal To (!=) operators in C#

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 bool operator==(Sample S1, Sample S2)
        {
            return (S1.X==S2.X);
        }

        public static bool operator !=(Sample S1, Sample S2)
        {
            return (S1.X != S2.X);
        }
        
    }

    class Program
    {
        static void Main()
        {
            Sample S1 = new Sample();
            Sample S2 = new Sample();
           
            S1.Set(3);
            S2.Set(3);

            Console.WriteLine(""+(S1==S2));
            Console.WriteLine(""+(S1!=S2));
        }
    }
}

Output

True
False

In this program, we took two object of sample class. And here we overloaded both "Equal To" == and "Not Equal To" != operators. And both overloaded methods are returning Boolean value on the basis of == and != operators.
