I only see examples on the website for SFTP. Is it as simple as replacing the SshHostKey property (leaving it blank) and setting the SslCertificate property (with the path to the file)?

FYI - Windows 7 64-bit
Latest version of WinSCP via .NET Assembly

Thanks

Ok, finally was able to get a connection established, but the first time I tried to upload my test file it just hangs. I had to kill my program. Below is the SessionLogFile information....keep in mind that this information is repeated NUMEROUS times in the log file, there's some infinite loop going on.

Also, when I tried to run it a second time, it says that it cannot access my upload file because it's being used by another process....obviously WinSCP did not dipose of the resources.

Ok, I figured out where the infinite loop is occurring (not why though).

When calling the Session.PutFiles() method, do NOT specify the remotePath parameter as "." (double-quote period doublequote)! I was under the impression that that meant the "local directory"...apparently not in this case.

So, I then changed that value to String.Empty, now I get this error (and it stops in a timely manner):

Thanks to the thread entitle "Code to upload and download files via SFTP using WinSCP", I figured out what the issue is. For the remotePath property, if you don't want to change the remoteFolder to drop the file, enter "/" instead of anything else.

I will say the documentation is kind of lacking, and intellisese would be handy as well. Shouldn't be very hard to include in the next release.

Thanks andegre!

The documentation by purpose does not suggest you anywhere to try to upload to "current directory" as there's no way to set one.
Though, if you insist on using the initial current directory (i.e. the home directory), use "./" (the docs says clearly that the path should be terminated with slash).
Definitely not the "/". That's root directory (what might be home directory on some server set ups).
