It is also possible to create generic delegate types, which will be addressed in the next chapter.

The Interfaces of the System.Collections

Namespace

The most primitive container construct would have to be our good friend System.Array. As you

have already seen in Chapter 4, this class provides a number of services (e.g., reversing, sorting,

clearing, and enumerating). However, the simple Array class has a number of limitations; most

notably, it does not automatically resize itself as you add or clear items. When you need to contain

types in a more flexible container, one option is to leverage the types defined within the

System.Collections namespace.

The System.Collections namespace defines a number of interfaces (some of which you have

already implemented during Chapter 9). A majority of the classes within System.Collections imple-

ment these interfaces to provide access to their contents. Table 10-1 gives a breakdown of the core

collection-centric interfaces.
