Program To implement multi-cast delegates

7:28 PM - By azeheruddin khan 0

Description: - A delegate which refers to multiple methods during runtime is called as Multi-cast delegate which is derived from System.MulticastDelegate class. A multi-cast delegate can call multiple methods in a serial order. As all the methods of the multi-cast delegate are executed in a serial order, they should not return any value, if they are returning values then each method has to wait till its previous method has returned a value.  Thus, delegates are used to call multiple methods for an event at run time.


using System;

namespace MultiCastDelegate
    class Program
        delegate void operate(int x, int y);
        static void Main(string[] args)
            Operation o = new Operation();
            operate p = new operate(o.sum);
            p += o.difference;
            p += o.product;
            p(80, 90);
            p -= o.product;
            p(80, 90);


    public class Operation
        int c;
        public void sum(int a, int b)
            c = a + b;
            Console.WriteLine("the sum is " + c);
        public void difference(int a, int b)
            c = a - b;
            Console.WriteLine("the difference is " + c);
        public void product(int a, int b)
            c = a * b;
            Console.WriteLine("the product is " + c);
