title: I cannot delete a file via FTP
body: <p>I am trying to delete all the files in a folder via FTP. Below is the code I am trying.</p>
  
  <p><strong>Files</strong> is an array of strings each one if the name of a file in the folder with its extension. </p>
  
  <p>When I run it I get an a reply of 206 but when I look in the folder all the files remain. I tried variations of the code below, including adding a delay, but still cannot delete the files. What have I missed?</p>
  
  <pre><code> foreach (var FileName2 in Files)
       {
         if (File.Exists(txtbx_save_backup_to.Text + "/" + FileName2))
                  {
                      FtpWebRequest Delrequest = (FtpWebRequest)WebRequest.Create(ftp_address + "/Temp/Backup/" + FileName2);
                     Delrequest.Credentials = new NetworkCredential(username, password);
                     Delrequest.Method = WebRequestMethods.Ftp.DeleteFile;
  
                      Task.Delay(1000);
  
                      using (FtpWebResponse response2 = (FtpWebResponse)request.GetResponse())
                      {
                          rchtxtbx_backup_comms.AppendText("Deleted File, status " + response2.StatusDescription + "\r");
                          rchtxtbx_backup_comms.ScrollToCaret();
                      }
                  }
              }
  </code></pre>
