HttpWebRequest httpRequset = null;

HttpWebResponse httpResponse = null;

//POST登录信息获取返回结果，结果为0是为登录成功

httpRequset = (HttpWebRequest)HttpWebRequest.Create(postUrl);//创建http 请求

httpRequset.Method = "POST";//POST 提交

httpRequset.ContentType = "application/x-www-form-urlencoded";//以上信息在监听请求的时候都有的直接复制过来

httpRequset.Headers.Add("X-Requested-With", "XMLHttpRequest");

Stream stream = httpRequset.GetRequestStream();

stream.Write(bytes, 0, bytes.Length);

stream.Close();//以上是POST数据的写入

httpResponse = (HttpWebResponse)httpRequset.GetResponse();//获得 服务端响应

}

//WebClient 写法

Console.WriteLine(responsefromserver);

webClient.Dispose();
