The .NET Framework provides a rich suite of collection classes. With the advent of Generics in 2.0, most of these collection classes are now type safe, making for a greatly enhanced programming experience. The collection classes include the List, Dictionary, Sorted Dictionary, Queue, and Stack. The simplest collection is the Array, the only collection type for which Visual Basic 2005 provides built-in support. In this chapter, you will learn to work with single, multidimensional, and jagged arrays . Arrays have built-in indexers, allowing you to request the nth member of the array. The .NET Framework provides a number of interfaces, such as IEnumerable and ICollection, whose implementation provides you with standard ways to interact with collections. In this chapter, you will see how to work with the most essential of these. The chapter concludes with a tour of commonly used .NET collections, including List, Dictionary, Queue, and Stack.
