I'm considering Rebex File Server to make C/S application.
But I can't run your sample(FileServer_CS) project with a problem.
The Exception of "Specified charset is not supported" occurred on constructor of FileServer.
I couldn't find the way to set the charset before the constructor line.

My system environment is..
Windows 7 Professional Service Pack 1 64-bit
Using Korean(korea) - Microsoft IME

Error line is...

_server = new FileServer();

Stack Trace is...

This has been fixed in release 2016R1 of Rebex components.

Update: This bug has been fixed in Rebex File Server 2016 R1. The File Server SftpEncoding now defaults to UTF-8 on machines where default charset was multi-byte but not UTF-8.


the problem is that the FileServer constructor sets the ShellEncoding to Encoding.Default, which is a Korean encoding.

However, currently only single-byte encodings are supported by the FileServer.Settings.ShellEncoding and FileServer.Settings.SftpEncoding.

At the same time your system's Encoding.Default is multi-byte which is standard for Korean which results in the error that you are getting.

As a quick fix before we get an official solution, I added the possibility for you to specify a different DefaultShellEncoding as a static property on the FileServer class.

Please download the hotfix and give it a try with UTF8 like this:

FileServer.DefaultShellEncoding = Encoding.UTF8;
FileServer server = new FileServer();

// etc.

Let me know whether the File Server sample now runs for you.

Hi Tomas Knopp.
Finally I bought your File Server and SFTP Client.
But I can't use this hot fix.
Because I don't know how i can set licenseKey like below.
Rebex.Licensing.Key = "==XXXXXXXXXXXXX=="
Let me know how i can set the licensing.Key.
If i've already recieved my licenseKey Let me know that.
I have to do presentation in 36 hours with demo application.
Please help me again.

Hello, I sent a link to full versions of Rebex File Server and Rebex SFTP to your e-mail. Please use these instead of the trial version. You don't have to set any licensing key with the full version.

Thank you for your prompt response! :)
I'm always happy with your quick response and hot fix.
The source code you gave me works well in my case.
