System.ArgumentException illegal characters in pat

Question

I am using Path.Combine, and one of the strings contain a Unicode characters. I get {System.ArgumentException} exception; illegal characters in path.

According to MSDN filepath/name can have unicode characters. Why do I get this exception?

Edit: Here is the code:

Path.Combine("C:\PDM\Silver","Amabel Bender QQQ")

Answer 1

If you are using C# then I'm sure you need to escape the back-slashes

Path.Combine("C:\\PDM\\Silver","Amabel Bender QQQ")

not applicable if you are using VB though...

Answer 2

I figured out the problem. The second string contains a "tab" character in it causing the exception. (that didn't showed up when I pasted the string here)

Thanks everyone and sorry for the confusion.

Answer 3

You may have double quotes in your set of paths, since Path.InvalidPathChars includes double-quotes.

That would make your exception unrelated to your Unicode character...

Just saw your edit of your question: VB, no quotes.

So may be you have a non-printable character copied in your second string, which looks like a space, just before your 'QQQ' string ?
Try also if "Amabel BenderQQQ" or "AmabelBenderQQQ" work (just to test if it is related to 'QQQ' chars or to the space)
