I am working in .Net environment using C#. I need some alternative for the Stack data structure. Some kind of bound stack. The quantity of elements in the collection shouldn’t exceed some fixed specified number. And, if that number achieved and new element is pushed, than most older element must be deleted. I need this for storing commands for Undo/Redo strategies.
Johnny Coder has an implementation here: http://johnnycoder.com/blog/2008/01/07/undo-functionality-with-a-limited-stack/
