title: FtpWebResponse, the operation timed out
body: <p>I want to download files based on their date time from a ftp server..I can access this Ftp from CuteFtp third party and every thing is Okey..but when I run the code below at line <code>GetRespone()</code> I get this error:  the operation has timed out.
  I download a sample file from this FTP programmatically with webclient requet and it was fine..but I need to use <code>FtpWebRequest</code> to get listDirectoryDetail and webClient does not support that..and one more thing, there is an exception in request: <code>FtpWebRequest.ContentType</code> threw an exception of type <code>System.NotSupportedException</code>.</p>
  
  <p>here is my code:</p>
  
  <pre><code>Uri uri = new Uri("ftp://192.168.1.5:2100/");//the private address
          if (uri.Scheme != Uri.UriSchemeFtp)
          {
              return;
          }
          FtpWebRequest reqFTP;
          reqFTP = (FtpWebRequest)WebRequest.Create(uri);                             
          reqFTP.Credentials = new NetworkCredential("myuser", "mypass");
          reqFTP.KeepAlive = false;
          reqFTP.Method = WebRequestMethods.Ftp.ListDirectoryDetails;                               
          reqFTP.UseBinary = true;
          reqFTP.Proxy = null;
          reqFTP.UsePassive = false;
          FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
  </code></pre>
