Depending on the variance of the line you are extracting from, perhaps you could use a non-regex approach. Personally I would go down this route as RegEx syntax is tricky, but each to their own. In you example you could do something like:
string x = s.Replace("href=\"", string.Empty); // to remove first bit
x = x.Substring(0, x.IndexOf('\\'); // to remove last part.. or something like that, no visual studio to hand.

Thanks in advanced! How to do that in regex(Only cause the string has a lot of this href)...
Are you trying to parse an HTML document for its links? Then: no, do not use regex. There are libraries which can do that.
