Get the (last part of) current directory name in C#

Question

I need to get the last part of current directory, for example from /Users/smcho/filegen_from_directory/AIRPassthrough, I need to get AIRPassthrough

Answer 1

rather then using the '/' for the call to split, better to use the Path.DirectorySeparatorChar :

like so:

path.split(Path.DirectorySeparatorChar).Last() 

Answer 2

Well, to exactly answer your question title :-)

var lastPartOfCurrentDirectoryName = 
   Path.GetFileName(Environment.CurrentDirectory);

Answer 3

You can also use the Uri class.

new Uri("file:///Users/smcho/filegen_from_directory/AIRPassthrough").Segments.Last()

You may prefer to use this class if you want to get some other segment, or if you want to do the same thing with a web address.

Answer 4

var lastFolderName = Path.GetFileName(
    path.TrimEnd(Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar));

This works if the path happens to contain forward slash separators or backslash separators.
