感觉自写的正则没错啊,可就是什么也捕获不到,代码在里面,请高手改下,谢谢!!!

      public static void Main(string[] args) {
            //我想捕获的字串在是下面这句的里的http连接地址
            //document.write("<img src='http://image.58.com/showphone.aspx?t=v55&v=E511117D78B8E33565689DD9FA350ECC0' />")
            string phone =
                "document.write(\"<img src='http://image.58.com/showphone.aspx?t=v55&v=E511117D78B8E33565689DD9FA350ECC0' />\")";
            //下面是我写的pattern
           string pattern= @"document.write(""<img\s+src='(?<url>http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?)'\s+/>"")";
           Regex r = new Regex(pattern, RegexOptions.IgnoreCase);
           MatchCollection m = r.Matches(phone);
           for (int i = 0; i < m.Count; i++) {
               Console.WriteLine(m[i].Groups["url"].ToString());
           }

            Console.ReadKey(true);
        }

string pattern= @"document.write\(""<img\s+src='(?<url>http://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?)'\s+/>""\)";

括号有歧义
