       //为什么匹配不出来？对正则不太熟，想问下原因，以及如何修改

       //sHtmlText的内容 ：<CODE>2005</CODE><DES>listing product to trademe error:You can't have more than 10 custom shipping options.\r\n</DES>\r\n

        public static string[] GetHtmlImageUrlList(string sHtmlText)

        {

            string pattern = "<CODE>(?<code>[^<>]+)</CODE>.*<DES>(?<des>.*)</DES>";

            //string pattern1 = "<DES>(?<des>.*)</DES>";

            Regex regImg = new Regex(pattern, RegexOptions.IgnoreCase);

            MatchCollection matches = regImg.Matches(sHtmlText);    //搜索匹配的字符串 

            string[] result = new string[2];

            foreach (Match match in matches)

            {

                result[0] = match.Groups["code"].Value.ToString();

                result[1] = match.Groups["des"].Value.ToString();

            }

            return result;

        }
