	 StreamReader sr = null;
	 HttpWebResponse response = null;
	 HttpWebRequest request = null;
	 // 要注意的这是这个编码方式，还有内容的Xml内容的编码方式
	 Encoding encoding = Encoding.GetEncoding("UTF-8");
	 byte[] data = encoding.GetBytes(url);

	 // 准备请求,设置参数
	 request = WebRequest.Create(url) as HttpWebRequest;
	 request.Method = "POST";
	 //request.ContentType = "text/plain";
	 request.ContentLength = data.Length;

	 outstream = request.GetRequestStream();
	 outstream.Write(data, 0, data.Length);
	 outstream.Flush();
	 outstream.Close();
	 //发送请求并获取相应回应数据

	 response = request.GetResponse() as HttpWebResponse;
	 //直到request.GetResponse()程序才开始向目标网页发送Post请求
	 instream = response.GetResponseStream();
	 sr = new StreamReader(instream, encoding);
	 //返回结果网页(html)代码

	 string content = sr.ReadToEnd();
	 return content;
	 }
