OK, now the correct answer:

C#

string fileName = string.Format(
    "{0}{1}{2}{3}",
    path,
    System.IO.Path.DirectorySeparatorChar, //important: '\' is incompatible!
    fName,
    ".xlsx");

Other answers does not take into account that the directory separator in the form of '\' is not portable — so I could not accept them. In particular, it won't work on Unix (yes, support of Unix is a part of CLI standard, in practice, this code can be used on Linux, Unix, MAC, etc. using Mono).

Also, string.Format is reportedly of better performance then a set of string concatenations (using '+').

Thank you for attention to these details.

Solution 1

Try putting a '\' character between the path and the file name.

If that doesn't fix it, then we need to know the error message / exception detail.

Griff, sorry, you have one incorrectness: '\' is not portable. Please see my answer.
