Greeting

Thomas

In addition to Thomas' suggestion have a look at the Stack class
(System.Collections.Stack) it is usefull for holding historical state

you could for example pust a string onto the stack before each change is
applied to it, and if you need to undo just pop the stack until you reach the
historical state you want

Hi Lars

Further to the answers, you could have a look at the Command pattern, which
can be used to support undo/redo operations.
