Path.GetDirectoryName dose not work on linux

[HassanHashemi]

Consider this code snippet:

 var path = "zj\\qj\\zjqjyed9vclmuljlky2nxv-6v-Thumbs\\zjqjyed9vclmuljlky2nxv-6v01.jpg";
 var directory = Path.GetDirectoryName(path);
 Console.WriteLine(directory);

On Windows Path.GetDirectoryName(path) returns:

   zj\qj\zjqjyed9vclmuljlky2nxv-6v-Thumbs

Which is expected while on Linux returns empty.

dotnet --version:
.Net core 2.2.104

Windows environment:
Win10

Linux:
Ubuntu 18.04 LTS

On windows \ is the standard and / is the alt directory separator char. On linux / is the only separator char and \ is a valid filename character. So linux interprets the path you give it according to the local rules and finds no directory separator char to split on, this is behaving as expected.

Sorry, that was a terrible mistake.
