    return Encoding.UTF8.GetBytes(Result);
 }
    //with end of execute the webservice does not return data to client

[Serializable()]
    public class HostServer
    {
        public HostServer(TcpClient client)
        {
            Client = client;
        }
        public HostServer()
        {
        }

        private TcpClient Client;

        private HttpWebResponse _WebResponse;
        public HttpWebResponse WebResponse
        {

        }

public string ContactToServer(string requestinput)
       {

           string url = GetRequseUrl(requestinput);

           HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
           HttpWebResponse response = (HttpWebResponse)request.GetResponse();
           
          
           String ver = response.ProtocolVersion.ToString();
           Stream d = response.GetResponseStream();

           StreamReader reader = new StreamReader(d);
           string res = string.Empty;
           try
           {
              res= reader.ReadToEnd();
             
           }
           catch
           {
           }

           reader.Close();
           d.Close();

           return res;

       }

}

推荐答案

对于长数据更好地创建异步回调

for long data better create asynchronous callbacks
