I have a regex like this:
name = dr-det-fb.ydp.eu/ebook/trunk/annotations/ctrl.php/api1751-4060-1193-0487 name = Regex.Replace(name, @"/\W/g", "");
This regex should replace "/", "-", "." with "". But it doesn't, can someone explain me why?
Do not use regex delimiters:
name = Regex.Replace(name, @"\W", "");
<action>/<pattern>(/<substituiton>)/modifiers regex declaration.
Just to avoid terminology confusion: inline modifiers (enforcing case-insensitive search, multiline, singleline, verbose and other modes) are certainly supported and can be used instead of the corresponding
RegexOptions flags (though the number of possible
RegexOptions flags is higher than that of inline modifiers). Still, regex delimiters do not influence the regex pattern at all, they are just part of declaration syntax, and do not impact the pattern itself. Say, they are just kind of substitutes for
; or newline separating lines of code.
In C#, regex delimiters are not necessary and thus are not supported. Perl-style
s/\W//g will be written as
var replaced = Regex.Replace(str, @"\W", string.Empty);. And so on.
