How do I use a collection?

Does anyone have any sample code for storing
information taken from a text box into a collection, then saving & retreiving the collection to/from a text file?

Besides code, advice would be appreciated also.

Thanks.

I've posted several answers that use collections. This one is probably the most appropriate, but you can find the others if you want by looking for my user name and the word collection, in all open forums.
