带有\\ w和德语特殊字符的C＃正则表达式？

Question

I need to capture some text with \\w, but this text can contain german Umlaute (Ü Ä Ö), which causes my regex to fail. How can I extend the regular expression to match these cases?

The regex:

Regex PFileRegex = new Regex("printfile ps *\\t*= *\\t*\"[\\w\\s]*.ps\\s*\"", RegexOptions.IgnoreCase);

 Match PFilematch = PFileRegex.Match("printfile ps = EXAMPLE Ä.ps"); //false
 Match PFilematch = PFileRegex.Match("printfile ps = EXAMPLE.ps"); //true

I know I can simply add Ü Ö Ä to [\\w\\s]*, but that is not really extensible.

In .NET, \\w will match accented letters by default ( reference ). It looks like you made a mistake elsewhere, but as your code in the question is not syntactically valid, I don't exactly know where.

Here's the same code that I just cleaned up, it should work:

var fileRegex = new Regex(@"printfile ps\s*=\s*""[\w\s]*\.ps\s*""", RegexOptions.IgnoreCase);
var fileMatch1 = fileRegex.Match("printfile ps = \"EXAMPLE Ä.ps\"");
var fileMatch2 = fileRegex.Match("printfile ps = \"EXAMPLE.ps\"");

The unescaped regex is printfile ps\\s*=\\s*"[\\w\\s]*\\.ps\\s*" .
