C# program to demonstrate the example of an array of delegates

Program:

The source code to demonstrate the array of delegates is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to demonstrate an array of delegates.

using System;

delegate void MyDel();

class Sample
{ 
    static void Method1()
    {
        Console.WriteLine("\tMethod1 called");
    }

    static void Method2()
    {
        Console.WriteLine("\tMethod2 called");
    }

    static void Method3()
    {
        Console.WriteLine("\tMethod3 called");
    }

    static void Main()
    {
        MyDel[] del = new MyDel[3];


        del[0] = Method1;
        del[1] = Method2;
        del[2] = Method3;

        Console.WriteLine("Invoke methods using delegates:");
        for (int i = 0; i < 3; i++)
        {
            del[i]();
        }
    }
}

Output:

Invoke methods using delegates:
        Method1 called
        Method2 called
        Method3 called
Press any key to continue . . .

Explanation:

In the above program, we created a Sample class that contains four static methods Method1() and Method2(), Method3(), and Main().

Method1(), Method2(), Method3(), and Method4() are used to print a message on the console screen. In the Main() method we created the array of delegates and bind the methods with delegates.

Console.WriteLine("Invoke methods using delegates:");
for (int i = 0; i < 3; i++)
{
    del[i]();
}

In the above code, we invoked the methods using an array of delegates using an index.
