I'm quite new to C#, and i was wondering how would i make a program that can read and write to a certain offset of a file, see im trying to make a tag creator/editor for the game Halo.

so i guess what im asking... is how would i make it so say... offset 40 of the file being opened (lets says its 3f 80), how would i get '1' to display in say textBox1... lol sorry if this is confusing :P

edit: i did some research and i found what i need to do, its called Binary Streaming, anyone know how to do this :P the tutorial i found isnt to noob friendly -_-
