C# program to overload less than (<) and greater than (>) operators

Overload less than (<) and greater than (>) operators in C#: Here, we are writing a program to overload less than and greater than relational operators.
Submitted by IncludeHelp, on March 18, 2018

In C#, if we overload "less than" (<) operator then we must overload "greater than" (>) operators. Here, we will create a sample class with data member X. Assign value using Set() method.

Problem statement

Write a C# program to overload less than (<) and greater than (>) operators.

Program to overload less than (<) and greater than (>) 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(5);
            S2.Set(3);

            Console.WriteLine(""+(S1 < S2));
            Console.WriteLine(""+(S1 > S2));
        }
    }
}

Output

False
True

In this program, we took two object of sample class. And here we overloaded both "less than" (<) and "greater than" (>) operators. And both overloaded methods are returning Boolean value on the basis of "<" and ">" operators.
