经测试通过:
static void Main(string[] args) { Regex r = new Regex("http:.*?\""); string source ="<img src=\"http://act.shangpin.com/brand/Activities/201402270310bluegirl/images/img01.jpg\" width=\"1900\" height=\"540\" border=\"0\" />"; string dest = r.Replace(source, new MatchEvaluator(x =>"/aolai/images/e.gif\" lazy=\""+ x.ToString())); Console.Read(); }
