Я пытаюсь использовать HttpWebRequest в приложении WP7, но у меня проблема.Я никогда не получаю ответ от сервера: /
Что я делаю не так?
Вот код неисправного мира ...
Класс Util
public class RequestState
{
// This class stores the State of the request.
const int BUFFER_SIZE = 1024;
public string requestData;
public byte[] Data
{
get
{
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] encodedPostData = ascii.GetBytes(this.requestData);
return encodedPostData;
}
}
public byte[] BufferRead;
public HttpWebRequest request;
public HttpWebResponse response;
public RequestState()
{
BufferRead = new byte[BUFFER_SIZE];
requestData = string.Empty;
request = null;
}
}
