Give me my data, and a side of Hash();
Currently on MSDN there is an interesting 6 part article written by Scott Mitchell-4GuysFromRolla.com fame and author. It is a 6 part series titled "An Extensive Examination of Data Structures", as of now parts I and II are available. Part 2 is particularly interesting to me because I use Hashtables all the time ( and the scaled down version called the ListDictionary() which lies in System.Collections.Specialized )
This article covers The Queue, Stack, and Hashtable in depth and is a great read, plus it's in C#!!!!!
Check 'em out
