Question

There is probably an easy answer for this, but when I added DateTime.Now.ToString() to my fileName it adds an extra \ for every \ I have so C:\Temp becomes C:\\Temp which causes the file not to save.

This is the code in question

String fileName = @"C:\Temp\data_" + DateTime.Now.ToString() + ".txt";

For example the output could be C:\\Temp\\data_12/04/2012 20:08:40.txt

It should be C:\Temp\data_12/04/2012 20:08:40.txt

Nope, that string really has single backslashes in. Print it out to the console and you’ll see that.

If you look at it in the debugger, you’ll see the backslashes escaped – but the string itself has single backslashes. This bites lots of people 🙁
