Android Question Correct way to test FTP connection?

[barx]

When using the FTP object in the Net library, what would be the correct / best way to test a connection. i.e. check the credentials are right for beginning transfers?

I thought of sending a 'List' request but would this fail if the directory was empty?

or maybe upload a dummy file. and delete it after checking for success.

Thanks

i think the best way is doing a chdir to / or something...
An empty directorylisting should work also...

How is that achieved?
Something like

FTP.SendCommand("CHDIR", "/")

Thanks

List will not fail if the folder is empty. The arrays lengths will be 0. However you should ignore that and check the value of the Success parameter.

The answer is that List will not fail if the folder is empty.
