I am trying to upload files in a winforms application (c# dotnet 4.6)

My code is very simple :

using (FTPConnection ftpConnection = new FTPConnection())
{
                        ftpConnection.ServerAddress = _ftpDefinition.Host;
                        ftpConnection.ServerPort = _ftpDefinition.Port;
                        ftpConnection.UserName = _ftpDefinition.UserName;
                        ftpConnection.Password = _ftpDefinition.PassWord;

                        FTPConnection.LogLevel = EnterpriseDT.Util.Debug.LogLevel.All;
                        FTPConnection.LogFile = @"C:\test\ftplog\ftp_log.txt";
 
                        ftpConnection.Connect();
                        ftpConnection.ChangeWorkingDirectory(remoteDir);
                        ftpConnection.UploadFile(localDir + fileName, fileName);
                        ftpConnection.Close();
}

From what I read in the logfile it looks like if the file has been transferred.
But if I look at the folder using an ftpclient (filezilla and Total Commander) then the file is not there.

Both FTP Clients cannot see it.
What can cause this and how to fix it ?

 

The entire log is here :

Filezilla does cache directory listings, so make sure you close it and restart. Also ensure the file is going to the location you think it is.

I do close the connection in filezilla before retrieving a list so that should not be the problem. If I drag the file from explorer to filezilla than I can see that file, but not the file that is uploaded using this library. As for the location, I do see the correct changedir in the log file. I will upload the entire log.

I also tried with actually closing and restarting filezilla, still no changes. The file is still not there or not visible but the log keeps saying it has transferred the file.
by (130 points)
I also tried with Total Commander and the same result. The log says the file is transfered, but both Total Commander and FileZilla cannot see it

I'm sorry, but this is clearly a server issue.  Please contact the vendor of the server software.

I"m sorry but this is NO server issue. If it was a server issue than files I upload using FileZilla or TotalCommander would also be not visible. And that is not the case.

It is clearly an issue of the uploading library in my opinion.

I'm sorry.  I didn't mean to ignore your comment; it just got lost in my inbox.

Yes, I agree that it's strange that it works in FileZilla but not with edtFTPnet/PRO.  I missed that bit of information previously.

Have you got access to the server logs?  If so then it would be interesting to see if you can see the file being uploaded successfully, and if anything happens to it afterwards.
by (130 points)
Unfortunate I do not have access to the logs of that server.
All I can do is use the webinterface of that company and retrieve a list of uploaded/downloaded files. In that list the files I have uploaded are present. That is how I know that the files did indeed uploaded. I asked the same question to this  company but have received no answer yet, except that this is a low priority ticket.
So I guess there is not much that we can do ?

Have you tried uploading using the command-line FTP client, ftp.exe?  After you upload the file, list the directory.  It will be interesting to see if the file is there.
by (130 points)
No, but I did tried listing the directory using the command-line FTP client and it always resulted in a "hanging" command-line FTP client. I think it must be a combination of some exotic server setting and ftp client but without assistance from the company that manages the ftp server this will be difficult to solve.

Yeah, I think you might have to wait for support to get back to you.

I have the same problem in FTP Client. I tried to write log detail, and I found the 'uploadfile' method of FTP client that it sometimes will send file to root directory because the method will change directory to root directory before upload file,
so I can't see the file in correct directory.
Please to check the action of the 'uploadfile()' method. Why does it sometimes change directory to root directory before?
=================
My program is as follow:
    //??????????remote??
                            MainFTP.objWriteFileLog.DebugWrite("DO_FTP.doSend_FTP()", $"6_ChangeWorkingDirectory????Server??? = {objFtp.ServerDirectory}?MainFTP.vFTP_PARA[16] = {MainFTP.vFTP_PARA[16]}", MainFTP.sMsgGUID);
                            objFtp.ChangeWorkingDirectory(MainFTP.vFTP_PARA[16]);
                            MainFTP.objWriteFileLog.DebugWrite("DO_FTP.doSend_FTP()", $"6_ChangeWorkingDirectory????Server??? = {objFtp.ServerDirectory}", MainFTP.sMsgGUID);

 MainFTP.objWriteFileLog.DebugWrite("DO_FTP.doSend_FTP()", $"7_UploadFile??Server???:{objFtp.ServerDirectory}?UploadFile:MainFTP.sBufSendName={MainFTP.sBufSendName.ToString()}", MainFTP.sMsgGUID);                                 
                                    objFtp.UploadFile(sMainFilePath + MainFTP.sBufSendName.ToString(), MainFTP.sBufSendName.ToString());                            
                                    MainFTP.objWriteFileLog.DebugWrite("DO_FTP.doSend_FTP()", $"7_UploadFile??Server???:{objFtp.ServerDirectory}", MainFTP.sMsgGUID);

I've looked at your log and it's clear that it's changing to the directory, /dw/ftpdata/ftpucc1, just before it uploads the file.  It's not clear why it's doing this though.  Can you please paste the code that calls our component into your reply?
by (110 points)
objFtp ==> is edtFTP component object

My program is as follow:
     //Check changedirectory to correct directory
             MainFTP.objWriteFileLog.DebugWrite("step 6_ChangeWorkingDirectory Before?Server??? = {objFtp.ServerDirectory}?MainFTP.vFTP_PARA[16] = {MainFTP.vFTP_PARA[16]}", MainFTP.sMsgGUID);
              objFtp.ChangeWorkingDirectory(MainFTP.vFTP_PARA[16]); ==> only change to MainFTP.vFTP_PARA[16] = /dw/ftpdata/ftpucc1/upload  

                             MainFTP.objWriteFileLog.DebugWrite("DO_FTP.doSend_FTP()", $"step 6_ChangeWorkingDirectory AFTER?Server??? = {objFtp.ServerDirectory}", MainFTP.sMsgGUID);

  MainFTP.objWriteFileLog.DebugWrite("DO_FTP.doSend_FTP()", $"step 7_UploadFile Before?Server???:{objFtp.ServerDirectory}?UploadFile:MainFTP.sBufSendName={MainFTP.sBufSendName.ToString()}", MainFTP.sMsgGUID);                                 
                                     objFtp.UploadFile(sMainFilePath + MainFTP.sBufSendName.ToString(), MainFTP.sBufSendName.ToString());                            
                                     MainFTP.objWriteFileLog.DebugWrite("DO_FTP.doSend_FTP()", $"7_UploadFile AFTER?Server???:{objFtp.ServerDirectory}", MainFTP.sMsgGUID);

=================

detail as up message (you can check the program and my log, edtFTP log), and then you will see step 6. ==> step 7 ; 7 only doing uploadfile() , and 6 only doing change to [/dw/ftpdata/ftpucc1/upload])

and then, you can check edtftp log and  my log of program , you will see the "uploadfile()"  method do two action, first is change to root folder, and second step is upload file.

so your should check the action of "uploadfile()" method.

I really need to see all of the code that's using our component, to be able to tell what's going on.  When I have this sort of problem within a large application, I often create a small stand-alone test project that isolates the problem that I'm trying to solve, so if I were you I would create a test project that replicates the problem.  It usually only takes a few minutes to do and doing it often makes the problem quite obvious.  If it doesn't reveal the problem then I would be happy to try it out, provided you have a current support agreement.

My program is not very large, and it is a stand-alone. It is a console for doing one receive or send action. I have another program for checking all tasks those need to send or receive, and then the program will call the console to do one task(This console just using your component). The console have more than one in the same time because we have more files to send different FTP Server.

The problem  is not happen erery times, so I am difficult to get it question by once connection.

The send method is as follow:

other program call
Do_FTP.doSend_FTP();

I will change logLevel to ALL for get more information.

  SecureFTPConnection.LogLevel = LogLevel.All;

Thanks!

You're mixing synchronous and asynchronous methods, which is not advisable since you have no control of which sequence operations are carried in.

In doSend_FTP() you call doConnection().  In doConnection() you invoke BeginGetFileInfos and then the method returns.  doSend_FTP() then goes on to call ChangeWorkingDirectory() and then UploadFile().  Since BeginGetFileInfos() instructs SecureFTPConnection to get a file listing on a worker thread, this operation will happen concurrently with ChangeWorkingDirectory() and UploadFile(), which could cause the behaviour that you're seeing.

I don't know why you're calling BeginGetFileInfos() since you don't appear to be using the listing for anything, but if you do need to do it then you should use the synchronous version, i.e. GetFileInfos().
by (110 points)
Maybe BeginGetFileInfos() in doConnection() is a question because I don't understand why the console read root folder sometimes, and that is not an instruct from my program.

I will change the console program for deleting objFtp.BeginGetFileInfos() method in
doConnection() method, and then care it.

Does happen change to root directory due to the same login user connection to FTP Server in different the console processes or different clients?

Thanks!!
