I have a database (well 10 files .txt within a folder) with 10 different student's infos. I need to take out all 10 final notes form each of them to make an average within a textbox.text (in C#) when I click a button. Actually I have 10 files now but it has to calculate even if it has 100 or 1000 files.
I don't even know from where to start... any clue guys? Thanks
