Answer 1

The default.Net implementation of Regex is slightly different from the Javascript implementation.

Differences are described on on the Microsoft website .

To use Javascript/ECMAscript rules in.Net:

   str = Regex.Replace(str, @"[^\w\\-]+", "", RegexOptions.ECMAScript);

Answer 2

You could try using a Alphabetic range like that:

str= (new Regex(@"[^A-Za-z0-9]+")).Replace(str, "");
