A useful pattern you need to be familiar with is the Chain of Responsibility pattern so we will use it as an example. With this pattern, we will set up a collection or chain of classes for handling a request. The idea is the request will pass through each class until it is handled. This illustration uses a car service center, where each car will pass through the different sections of the center until the service is complete.
Let's start by defining a collection of flags that will be used to indicate the services required:
[Flags]enum ServiceRequirements{ None = 0, WheelAlignment = 1, Dirty = 2, EngineTune = 4, TestDrive = 8}
The FlagsAttribute in C# is a great way of using a bit field to hold a collection of flags. ...
