Hello.  New to the Windows world and .NET programming.  Below is a snippet of code (pulled from the internet) that get's a listing of files from an FTP server.  The try/catch code check for the success/failure of the whole operation, but I'd like to get a status from the "WebResponse response = reqFTP.GetResponse();" line of code.  How can I get the status?

Thank you
FtpWebRequest reqFTP;

            try

            {

                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/"));

                reqFTP.UseBinary = true;

                reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);

                reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;

                WebResponse response = reqFTP.GetResponse();

                

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

                string line = reader.ReadLine();

                while (line != null)

                {

                    result.Append(line);

                    result.Append("\n");

                    line = reader.ReadLine();

                }

                // to remove the trailing '\n'

                result.Remove(result.ToString().LastIndexOf('\n'), 1);

                reader.Close();

                response.Close();

                return result.ToString().Split('\n');

            }

            catch (Exception ex)

            {

                downloadFiles = null;

                Console.WriteLine("Error {0}encountered while getting file list", ex);

                Console.ReadLine();

                return downloadFiles;

                

                

            }

You should be able to get the status from the response variable assuming it did not trap. A trap will occur in some situations like a bad Uri or a timeout, perhaps.
In addition, you could have additional "catch"es which will catch specific exceptions rather than the general "Exception" for additional reasons for the trap.

So are you saying to code like:

string myStatus = response.Status;

??  This is where I am getting hung up.  The response variable doesn't seem to have a "Status" method.

According to MSDN, "GetResponse" sets the Status property of WebExceptionStatus.  This is what I am trying to get.

I figured this one out.  Must something like:

catch (WebException e) {
.
.
.
}

I am such a newbie.

You can have these three all at once:
catch (HttpException e) {
.
}
catch (WebException e) {
.
}
catch (Exception e) {
.
}
