public class Car

Now, also assume the Car type nests a new delegate type named CarMaintenanceDelegate:

// Car defines yet another delegate.

public class Car

{

// Can call any method taking a Car as

// a parameter and returning nothing.

public delegate void CarMaintenanceDelegate (Car c);

...

}

Notice that the CarMaintenanceDelegate type can point to any function taking a Car as a param-

eter and returns nothing.

Delegates As Parameters

Now that you have a new delegate type that points to methods taking a Car parameter and returning

nothing, you can create other functions that take this delegate as a parameter. To illustrate, assume

you have a new class named Garage. This type maintains a collection of Car types contained in a

List. Upon creation, the List is filled with some initial Car types (be sure to import the

System.Collections.Generic namespace into your new code file):
