GUI FTP Client Windows Form Catch Web exception Issue. Need help.

Hi there,

I have managed to get it to return an error for "NotLoggedIn" but it will then proceed to crash anyway.

I also have it working (as in it logs in and displays the folders) when the correct details are entered.

public string[] ListDirectory()
         {
             var list = listView1;
             var request = createRequest("ftp://" + host.Text.ToString() + "/", WebRequestMethods.Ftp.ListDirectory);
             try
             {
                 FtpWebResponse response = (FtpWebResponse)request.GetResponse();
             }
             catch (WebException ex)
             {
                 FtpWebResponse response = (FtpWebResponse)ex.Response;
                 if (response.StatusCode == FtpStatusCode.NotLoggedIn)
                 {
                     MessageBox.Show(response.StatusDescription);
                 }
             }
             using (var response = (FtpWebResponse)request.GetResponse())
             {
                 using (var stream = response.GetResponseStream())
                 {
                     using (var reader = new StreamReader(stream, true))
                     {
                         while (!reader.EndOfStream)
                         {
                             list.Items.Add(reader.ReadLine());
                         }
                     }
                 }
             } List<string> l = new List<string>();
             return l.ToArray();
         }

I need it to display a webexception error, without crashing afterwards.

I tried moving....

 using (var response = (FtpWebResponse)request.GetResponse())
             {
                 using (var stream = response.GetResponseStream())
                 {
                     using (var reader = new StreamReader(stream, true))
                     {
                         while (!reader.EndOfStream)
                         {
                             list.Items.Add(reader.ReadLine());
                         }
                     }
                 }
             } List<string> l = new List<string>();
             return l.ToArray();

 as an ELSE statement in response to the catch IF statement.

But then it didn't work. Any advice please?
