Program:

The source code to declare and instantiate delegate is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to declare and instantiate delegate.

using System;

delegate void MyDel();
class Sample
{ 
    void Method1()
    {
        Console.WriteLine("Method1() called");
    }

    static void Main()
    {
        Sample S = new Sample();
        MyDel del = new MyDel(S.Method1);

        del();
    }
}

Output:

Method1() called
Press any key to continue . . .

Explanation:

In the above program, we created a Sample class that contains a method instance Method1() and static method Main().

Method1() is used to print a message on the console screen.

delegate void MyDel();

Here we created a delegate according to the method declaration.

MyDel del = new MyDel(S.Method1);
del();

In the above code we bind the Method1() to the delegate del and called the method Method1() using delegate del that will print "Method1() called" on the console screen.
