This is bizarre. Is it possible that the file is being truncated on the server while you are downloading?

Have you tried using FIlezilla, and if so, was it successful?

Let me try again

Okay, now i can post code.  I kept getting errors from the server.

This is the code:

 var ftp = new FTPConnection()
            {
                ConnectMode = FTPConnectMode.PASV,
                ServerAddress = CitFtpSite,
                UserName = CitUserName,
                Password = CitPassword,
                TransferType = FTPTransferType.BINARY,
                ServerDirectory = "/Outbox"
            };
            ftp.Connect();
            FTPConnection.LogLevel  = LogLevel.Debug;
            FTPConnection.LogFile = @"P:\logs.txt";
        var filename = Environment.CurrentDirectory +@"\"+ string.Format("CCData{0:MMddyyhhMMss}.txt",DateTime.Now);
            //try
            {
                ftp.DownloadFile(filename,"CCDATA.TXT");
            }

When I get the error, I get this log entry:

The thing is I'm not trying to send a REST or get file size.  I just want to download the file, and they won't let us use our VAN to send or retrieve the files.

I was able to use the Windows command line FTP to do it, and it was successful (did not get any errors), so I am thinking the EnterpriseDT library is triggering something.

Please post the Windows log - you can show the commands sent by typing "debug".

It occurred to me that it is probably barfing at the earlier "REST 0" command, which I only just noticed.

Is this edtFTPnet? Which version?
by (120 points)
It is edtFTPnet and it's version 2.2.2.0 according to the reference.
by (120 points)
Anyone??  I need to know what to do.
by (162k points)
Try the latest version, 2.2.3. It looks like it may be fixed in that version.
by (120 points)
Okay, just downloaded and will try it.
by (120 points)
It didn't help.  Here's the log from where the .NET ran (and I verified it was using the 2.2.3 version):

Ok, I'll take a look tomorrow - I'm pretty sure we've fixed this so it may not be out in edtFTPnet.

I've got a new build for you to try - please email support at enterprisedt dot com for a link.
