1、传入客房描述，将客房描述中所有图片的src取出，放入集合中，并返回集合

        private static List<string> GetInputImgUrls(string HTMLStr)
        {
            List<string> pics = new List<string>();

            string str = string.Empty;
            Regex r1 = new Regex(@"<input/s+[^>]*/s*src/s*=/s*([']?)(?<url>/S+)(/S[']?)[^>]*>", RegexOptions.IgnoreCase);
            MatchCollection urls1 = r1.Matches(HTMLStr);
            foreach (Match match1 in urls1)
            {
                if (match1.Success)
                {
                    str = match1.Result("${url}");
                    pics.Add(str.Substring(1));
                }
            }
            if (pics.Count == 0)
            {
                Regex r2 = new Regex(@"<img/s+[^>]*/s*src/s*=/s*([']?)(?<url>/S+)(/S[']?)[^>]*>", RegexOptions.IgnoreCase);
                MatchCollection urls2 = r2.Matches(HTMLStr);
                foreach (Match match2 in urls2)
                {
                    if (match2.Success)
                    {
                        str = match2.Result("${url}");
                        pics.Add(str.Substring(1));
                    }
                }
            }
            return pics;
        }

2、从集合中取出第一张作为显示

        public static string getFirstImageUrl(string url)
        {

            List<string> list = GetInputImgUrls(url);
            if (list.Count > 0)
            {
                return list[0];
            }
            return "";
        }
