[Mono-list] Is it the intended behavious?

[Moritz Balz]

Was there already a bug filed for this? (Did'nt find any.)
I struggled with this for the last days.

It seems that directory names do never end with "/"
So calling DirectoryInfo.Parent from, say, "/home", returns "".

But the root dir itself is "/", so there is some inconsistency.
"" is never recognized as root dir, so the Parent of "" returns
something - the current directory, or sometimes null.

I think either all dir names must end with "/", or "" must denote the
root dir.
