      string strUrl = "http://xml.sz.luohuedu.net/HttpReceiveData.aspx";
      postData += ("&Desc=" + strDesc);
      byte[] data = encoding.GetBytes(postData);      // 准备请求...
      HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(strUrl);
      myRequest.Method = "POST";
      myRequest.ContentType="application/x-www-form-urlencoded";
      myRequest.ContentLength = data.Length;
      Stream newStream=myRequest.GetRequestStream();
      // 发送数据
