I have a dictionary of strings that i want the user to be able to add/remove info from then store it for them so it they can access it the next time the program restarts
Have you considered using XML to store your dictionary? That would provide a certain amount of extensibility if in the future you decide you want to be able to store other types of dictionaries. You might do something like:
[whatever data you like]
Might be overkill, but you'd also be prepared in the case that you wanted to store more complex data, like custom objects.
