// Note that this method accepts a greetingdelegate method as a parameter.
Private Static void greetpeople (string name, greetingdelegate makegreeting ){

}< BR >}< br> the delegate is a class that defines the type of the method, this allows the method to be passed as a parameter of another method. In this way, the method is dynamically assigned to the parameter, you can avoid using the IF-else (switch) Statement extensively in the Program , and make the program more scalable.
