C# program to demonstrate the example of generic delegate

//C# program to demonstrate generic delegate.

using System;

using System.Collections.Generic;
delegate T MyDel<T>(T n1, T n2);

class Sample
{ 
    static int Add(int num1, int num2)
    {
        return(num1+num2);
    }

    static int Sub(int num1, int num2)
    {
        return (num1-num2);
    }

    static int Mul(int num1, int num2)
    {
        return (num1*num2);
    }

    static int Div(int num1, int num2)
    {
        return (num1/num2);
    }

    static void Main()
    {
        int result = 0;
        int num1   = 0;
        int num2   = 0;

        MyDel<int> del1 = new MyDel<int>(Add);
        MyDel<int> del2 = new MyDel<int>(Sub);
        MyDel<int> del3 = new MyDel<int>(Mul);
        MyDel<int> del4 = new MyDel<int>(Div);

        Console.Write("Enter the value of num1: ");
        num1 = int.Parse(Console.ReadLine());

        Console.Write("Enter the value of num2: ");
        num2 = int.Parse(Console.ReadLine());

        result = del1(num1,num2);
        Console.WriteLine("Addition:       " + result);

        result = del2(num1, num2);
        Console.WriteLine("Subtraction:    " + result);

        result = del3(num1, num2);
        Console.WriteLine("Multiplication: " + result);

        result = del4(num1, num2);
        Console.WriteLine("Division:       " + result);
    }
}

Output

Enter the value of num1: 8
Enter the value of num2: 5
Addition:       13
Subtraction:    3
Multiplication: 40
Division:       1
