Solution 1

Try this:

C#

string regexSearch = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
Regex r = new Regex(string.Format("[{0}]", Regex.Escape(regexSearch)));

Cheers,
Edo

Thank you very much!
But i hardly used Regex until now, how do i use it with my string now?
I tried r.Machtes(MyString);
But it seems not legit

String illegal = "Your string here. The regex will remove the illegal chars from it.";
... The code in the sample I showed ...
illegal = r.Replace(illegal, "");

Ok i got it, it works like that:

string nameWithoutUnallowedSigns = RemoveSigns.Replace(name, "");

instead of your:
string tempName = name;
RemoveSigns.Replace(name, "");

use:
string tempName = RemoveSigns.Replace(name, "");
