	 WebRequest request = WebRequest.Create("http://www.baidu.com/");
	 // If required by the server, set the credentials.
	 request.Credentials = CredentialCache.DefaultCredentials;
	 // Get the response.
	 HttpWebResponse response = (HttpWebResponse)request.GetResponse();
	 // Display the status.
	 MessageBox.Show(response.StatusDescription);
	 Console.WriteLine(response.StatusDescription);
	 // Get the stream containing content returned by the server.
	 Stream dataStream = response.GetResponseStream();
	 // Open the stream using a StreamReader for easy access.
	 StreamReader reader = new StreamReader(dataStream, Encoding.Default);
	 // Read the content.
	 string responseFromServer = reader.ReadToEnd();
	 //截取数据
	 int i = responseFromServer.IndexOf("京");
	 string dataBid = responseFromServer.Substring(i, 12);

	 // Display the content.
	 MessageBox.Show(dataBid);
	 Console.WriteLine(responseFromServer);
	 // Cleanup the streams and the response.
	 reader.Close();
	 dataStream.Close();
