Exception with GetFiles() with Remove on Directory

2015-03-20 15:16

Hello, this is my first issue i have come across with WinSCP, I am getting an error when i use the GetFiles() method and use the Remove Parameter and it is for a directory. It seems to work find when I get just a file.

Here is my set up:

WinSCP 5.7.0.0
Windows 8.1 x64 Enterprise
PowerShell V4
FileZilla FTP Server running locally.

Here is my Code:

$so = New-Object WinSCP.SessionOptions
$so.UserName = "MyUser"
$so.Password = "MyPassword"
$so.HostName = "127.0.0.1"
$so.Protocol = "Ftp"

$s = New-Object WinSCP.Session
$s.Open($so)

$s.GetFiles("./TestFolder", "C:\Local\TestFolder", $true)

And it is throwing the following error:

Exception calling "GetFiles" with "3" argument(s): "Operation is not valid due to the current state of the object."

But, it is actually transfering the folder, and removing it from the source. And here is the FileZilla info, with no errors:

Re: Exception with GetFiles() with Remove on Directory

Thanks for your report.

Please attach a full session and debug log files showing the problem (using the latest version of WinSCP).

To generate log files, set Session.SessionLogPath and Session.DebugLogPath. Submit the log with your post as an attachment. If you do not want to post the logs publicly, you can mark the attachments as private.

Also, can you see a callstack of the exception?

Cannot get logs to run

2015-03-20 17:08

here is my code:

$so = New-Object WinSCP.SessionOptions
$so.UserName = "MyUser"
$so.Password = "MyPassword"
$so.HostName = "127.0.0.1"
$so.Protocol = "Ftp"

$s = New-Object WinSCP.Session

$s.DebugLogPath = "C:\Local"
$s.SessionLogPath = "C:\Local"
$s.Open($so)

$s.GetFiles("./TestFolder", "C:\Local\TestFolder", $true)

$s.Close()

i get access denied message for the debug log. I tried a few differnt locations, and i gave everyone full control to the path in the code. If i comment that out and only try to use the sessionlog, i get this:

Exception calling "Open" with "1" argument(s): "Error occurred during logging. It's been turned off."

i will keep trying to get that to work.

here is the full error i get for the GetFiles() exception:

Exception calling "GetFiles" with "3" argument(s): "Operation is not valid due to the current
state of the object."
At line:12 char:1
+ $s.GetFiles("./TestFolder", "C:\Local\TestFolder", $true)

Sorry, i didn't know you had to actually specify a file name for the log(s). So here they are.

Thanks again.

session.log (6.49 KB, Private file)

Description: session log

debug.log (34.58 KB, Private file)

Description: debug log

Do you have a callstack of the exception?

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

You will find my address (if you log in) in my forum profile.
