The default .Net implementation of Regex is slightly different from the Javascript implementation.(Regex的默认.Net实现与Javascript实现略有不同。)

Differences are described on on the Microsoft website .(差异在Microsoft网站上有描述。) To use Javascript/ECMAscript rules in .Net:(在.Net中使用Javascript / ECMAscript规则：) str = Regex.Replace(str, @"[^w\-]+", "", RegexOptions.ECMAScript);
