The Non-Generic Collection Classes.

With the exception of BitArray, described later, the non-generic collection classes are summarized here:

ArrayList: A dynamic array. This is an array that can grow as needed.
Hashtable: A hash table for key/value pairs.
Queue: A first-in, first-out list.
SortedList: A sorted list of key/value pairs.
Stack A first-in, last-out list.
