        sw.Close();
    }
    catch(System.IO.DirectoryNotFoundException ex)
    {
        System.IO.Directory.CreateDirectory("E:Praisey\\" + txtAcc.Text + "\\Login.ID");
        var sw = new System.IO.StreamWriter("E:Praisey\\" + txtAcc.Text + "\\Login.ID");

well, maybe you are running with permissions that don't have access to that directory/file? — Icepickle, Oct 01 '15 at 09:24
You are creating `"E:Praisey\\" + txtAcc.Text + "\\Login.ID"` directory and then creating `StreamWriter` to the same path... Also, you might not have access to `E:\Praisey` directory. Which line exactly throws the exception? — tdragon, Oct 01 '15 at 09:26
@tdragon in var sw = new System.IO.StreamWriter("E:Praisey\\" + txtAcc.Text + "\\Login.ID"); — AlgorithNewbie, Oct 01 '15 at 09:29

This error occurs (had it yesterday too) when the Directory does not exist. You need to create it before starting your StreamWriter.

if (!Directory.Exists("E:Praisey\\" + txtAcc.Text))
    Directory.CreateDirectory("E:Praisey\\" + txtAcc.Text);

As I see from your catch block, "E:Praisey\\" + txtAcc.Text + "\\Login.ID" is actually a directory. You must also add the file name to the path.

var sw = new System.IO.StreamWriter("E:Praisey\\" + txtAcc.Text + "\\Login.ID\\filename.txt");
