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.
