I want to list all files from my ftp folder, I am using this code. But it gives me twice the name of files. What is wrong with it?

private void ListFilesOnServer()

        {

            try

            {

                FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ConfigurationSettings.AppSettings.Get("IncomingFtpPath"));

                request.Credentials = new NetworkCredential("user", "password");

                request.Method = WebRequestMethods.Ftp.ListDirectory;

                FtpWebResponse response = (FtpWebResponse)request.GetResponse();

                Stream responseStream = response.GetResponseStream();

                StreamReader reader = new StreamReader(responseStream);

                while (!reader.EndOfStream)

                {

                    var line = reader.ReadLine();

                    if (System.IO.Path.GetExtension(line) == ".xml")

                    {

                        WaitingListBox.Items.Add(System.IO.Path.GetFileNameWithoutExtension(line));

                    }

                }

                reader.Close();

                response.Close();

            }

            catch (Exception e)

            {

                MessageBox.Show(e.Message);

            }

        }

    Hi Tanuj, 


    private void ListFilesOnServer()

    {

            try

            {

         FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ConfigurationSettings.AppSettings.Get("IncomingFtpPath"));

                request.Credentials = new NetworkCredential("user", "password");

                request.Method = WebRequestMethods.Ftp.ListDirectory;

                FtpWebResponse response = (FtpWebResponse)request.GetResponse();

                using(StreamReader reader = new StreamReader(response.GetResponseStream())

                {

                   string line = null;

                   while((line = reader.ReadLine()) != null)

                   {

                    if (System.IO.Path.GetExtension(line) == ".xml")

                    {

                      WaitingListBox.Items.Add(System.IO.Path.GetFileNameWithoutExtension(line));

                    }

                   }

                }

            }

            catch (Exception e)

            {

                MessageBox.Show(e.Message);

                // throw e

            }
