Beginning C# 2008 Objects: From Concept to Code

13.5. C#'s Collection Classes

Back in Chapter 6, we discussed the need for a convenient way to collect references to objects as we create them, so that we can iterate over them, retrieve a particular object on demand, and so forth. We learned that the way to do so in an object-oriented programming language (OOPL) is to create a special type of object called a collection, and that one of the simplest collection types in C# is the fixed-size array. When we introduced arrays in Chapter 6, we alluded to the fact that they are objects in the C# language; as it turns out, the System.Array class is the basis for all arrays. We'll revisit arrays in this section to learn about some of the more interesting features of the System.Array class.
