fileput and fileopen equivalent in compact framework 3.5?

I am developing an application for windows mobile 6.5 and have a structure that I would like to save. I know that you can save/open structures in other frameworks using fileput and fileopen but these are missing within compact framework 3.5, how do you go about doing this?

Thanks

You shouldn't use FilePut and FileOpen in VB.NET at all. They are VB6 holdovers and should only ever be used in code that has been converted from VB6 and already uses them for the sake of compatibility. In new VB.NET code you should use members of the System.IO namespace, e.g. FileStream and BinaryReader/BinaryWriter, or else use binary or XML serialisation.
