C# Operator overloading

Whenever you overload an operator in C#, you have specific operator methods created that are related to the operator that you overload. Hence, when you overload the + operator, the overloaded operator method name is operator+. Note that all the overloaded operator methods are named "operator."  Further, all operator methods in C# are static.

namespace weight

{

    class weight

    {

        int kg;

        int mg;

        public weight()

        { }

        public weight(int a, int b)

        {

            kg = a;

            mg = b;

        }

        public void get_w()

    {

        Console.WriteLine("Enter the kilogram Object 2");

        kg = Convert.ToInt32(Console.ReadLine());

        Console.WriteLine("Enter the miligram Object 2");

        mg = Convert.ToInt32(Console.ReadLine());

    }

        public void display()

  {

Console.WriteLine("kilograms are   {0}  \nMile grams are  {1}", kg, mg);

}

        public static weight operator+(weight h1, weight h2)

        {

            int Kg, Mg;

            Kg = h1.kg + h2.kg;

            Mg = h1.mg + h2.mg;

            if (Mg >= 1000)

            {

                Kg++;

                Mg -= 1000;

            }

            else { }

            weight h3 = new weight(Kg, Mg);

            return h3;

        }

        static void Main(string[] args)

        {

            weight w1 = new weight(5, 600);

            weight w2 = new weight();

            w2.get_w();

            w2.display();

            w1.display();

            weight w3 = w1 + w2;

            w3.display();

        }

    }
