how to create a delegate in c#

Comment

//the delegate can point to a void function and takes a string parameter
delegate void Del(string str);

public void hello(string Name)
{
 	Console.WriteLine("hello " + Name) ;
}
public static void main()
{
  //you need to declare the delegate type above and give it a function
  //that matches the delegate's funcion 
  Del HelloDelegate = new Del(hello);
  HelloDelegate("IC");
}

        // Creating instances of the delegate and associating methods
        OperationDelegate operation = Calculator.Add;

        operation += Calculator.Multiply;
        operation += Calculator.Divide;

        // Invoking the delegate
        operation.Invoke(10, 5);
