Csharp / C# Multicast Delegate example

using System;

 

//observation: A delegate which takes two paramter of integer type.

public delegate void fnTwoInteger(int x,int y);

 

public class DelegateExample

{

    public static void Main()

    {

        ExmapleClass obj = new ExmapleClass();

 

        fnTwoInteger pointer=null;

 

        //observation: adding more than one function called multicast delegate.

        pointer += new fnTwoInteger(obj.Add);

 

        pointer += new fnTwoInteger(obj.Multiply);

 

        pointer(52, 72);

 

        Console.ReadLine();

    }

}

 

public class ExmapleClass

{

    public void Add(int x, int y)

    {

        Console.WriteLine("The sum is: " + (x + y));

    }

 

    public void Multiply(int x, int y)

    {

        Console.WriteLine("The product is: " + (x * y));

    }

}

Output:
The sum is: 124
The product is: 3744
