HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URL_WriteFeederMemory);
request.Method = "POST";
request.ContentType = "application/json";
SetWebRequest(request);
byte[] data_SA = Encoding.UTF8.GetBytes(str_WriteFeederMemory);
WriteRequestData(request, data_SA);
try
{
    WebResponse response = request.GetResponse();
    string str_response = ReadResponse(response);
    Console.WriteLine(str_response);
}
catch (WebException ex)

   request.Credentials = CredentialCache.DefaultCredentials;
   request.Timeout = 10000;
}

发送Request消息

private static void WriteRequestData(HttpWebRequest request, byte[] data)
{
   request.ContentLength = data.Length;
   Stream writer = request.GetRequestStream();
   writer.Write(data, 0, data.Length);
   writer.Close();
}

获取Response消息

private static string ReadResponse(WebResponse response)
{
   StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
   String retStr = sr.ReadToEnd();
   sr.Close();
   return retStr;
