正则表达式匹配Html代码中图片路劲

  //正则表达匹配图片路径
        public static string[] GetHtmlImageUrlList(string sHtmlText)
        {
            // 定义正则表达式用来匹配 img 标签
            Regex regImg = new Regex(@"<img/b[^<>]*?/bsrc[/s/t/r/n]*=[/s/t/r/n]*[""']?[/s/t/r/n]*(?<imgUrl>[^/s/t/r/n""'<>]*)[^<>]*?/?[/s/t/r/n]*>", RegexOptions.IgnoreCase);

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

            int i = 0;
            string[] sUrlList = new string[matches.Count];

            // 取得匹配项列表
            foreach (Match match in matches)
                sUrlList[i++] = match.Groups["imgUrl"].Value;

            return sUrlList;
        }
