目的，把远程服务器传回的Html，解析到类里面，为GridView等提供数据源

　　1 、向远程服务器Post数据

public int PostData(string url, string data, out string info)
        {
            info = "";
            CookieContainer cc = new CookieContainer();
            HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
            request.CookieContainer = cc;
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            Stream requestStream = request.GetRequestStream();
            byte[] byteArray = Encoding.UTF8.GetBytes(data);
            requestStream.Write(byteArray, 0, byteArray.Length);
            requestStream.Close();
            HttpWebResponse response = request.GetResponse() as HttpWebResponse;
            Uri responseUri = response.ResponseUri;
          &n
