GetFileInfos Encoding

in .NET FTP by (280 points)
Hi there, I've tried searching the forums for my solution, but I can't seem to find out whats wrong.

I've changed the encoding for the FTPConnection:

FTPConnection.DataEncoding = System.Text.Encoding.UTF8

I've tried:

FTPConnection.DataEncoding = System.Text.Encoding.Unicode
FTPConnection.DataEncoding = System.Text.Encoding.GetEncoding("Windows-1252")
FTPConnection.DataEncoding = System.Text.Encoding.GetEncoding("ISO-8859-1")

With no success, the filenames have Latin characters in them and on the server the letters are there, but when I use:

For Each file As EnterpriseDT.Net.Ftp.FTPFile In FTPConnection.GetFileInfos()
Debug.Print(file.Name)
Next

The letters are missing, like it just strips them from the name completely. Why isn't the encoding holding? I've connected with Filezilla Client and the directory listing from the server is fine, as Filezilla Client shows them. It just seems that setting the property for FTPConnection.DataEncoding isn't sticking.

Any ideas?

Do you get the same result using GetFiles()?

Thank you for your quick reply.

Yes, sorry for not mentioning it in my original post, I have tried GetFiles:

For Each s As String in FTPConnection.GetFiles()
Debug.Print(s)
Next

Same results.

I even enabled debug at level all and the debug information strips the letters also.

This is the debug with no command encoding, notice the "Reading ASCII listing data"

This is with ISO-8859-1 command encoding, notice the characters are there, but I'm stumped as why some have an extra character after it:

Any luck with this? Quite a lot of people use the encodings, I'm a bit puzzled as to why it doesn't work for you ...

No luck, haven't tried anything since I posted the debug log. Was hoping to get a reply with something I'm doing wrong that you saw in the log. I'm also puzzled. I'll try some very basic tests today and see if I can come up with something. Either way, I'll post my findings.

Ok, so the problem was still encoding, I just had to do some extra steps in my code:

First off, I set the command encoding: 

FTPConnection.CommandEncoding = System.Text.Encoding.GetEncoding("ISO-8859-1")


Then during my GetFiles I do:

Dim fileName As String = Text.Encoding.UTF8.GetString(Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(file.Name))
Debug.Print(fileName)

Dim fileRaw As String = Text.Encoding.UTF8.GetString(Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(file.Raw))
Debug.Print(fileRaw)


That fixed it for me.
