The best way?

Question

Hi, I'm looking for some advice, what would be the best (file based) way of storing information to be used in a list - such information as Id, Name, Age say for each person. I want to be able to show a list of the Names or Id's or Id with the Name next to it for each item (person) in the file based - mini database type thing :). I would also like to be able to Add/Edit/Delete sections from the list, so I could delete an item that is in the middle of the list. I was thinking XML but not to sure how I would go about doing this. I'm new to coding so not to sure, I would like to use C# for this :). Many Thanks, Richard
