Problem statement

To demonstrate an Example of Overloading Logical NOT (!) Operator in C#, here we are creating a sample class with data member X. Assign value using Set() method.

Program to overload Logical NOT (!) in C#

using System;
using System.Collections;

namespace ConsoleApplication1
{
    class Sample
    {
        private bool X;
        
        public Sample()
        {
            X = false;
        }

        public void Set(bool v)
        {
            X = v;
        }
        public static bool operator!(Sample S)
        {
            return !(S.X);
        }
        
    }

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

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

Output

False
True

In this program, we took two object of sample class. And here we overloaded "Logical AND (!) operator. And both overloaded methods are returning Boolean values on the basis of values set by Set() method.
