Get parent directory for some files C#

Question

I'm using

FolderBrowserDialog fbd = new FolderBrowserDialog();
string[] filePaths = Directory.GetFiles(fbd.SelectedPath, "*",SearchOption.AllDirectories);

filePaths are the following:

C:\Users\Stef\Desktop\bgdm_v2015\bgdm.dll
C:\Users\Stef\Desktop\bgdm_v2015\something.txt
C:\Users\Stef\Desktop\bgdm_v2015\folder2\file.txt
C:\Users\Stef\Desktop\bgdm_v2015\folder2\file2.txt
C:\Users\Stef\Desktop\bgdm_v2015\folder2\folder3\file.txt

Is there any function to get the parent directory to the files? Like only

bgdm_v2015
bgdm_v2015
bgdm_v2015
folder2
folder2
folder3

Path.GetDirectoryName returns the full path of the parent, and Path.GetFileName returns the last segment of the path (which can actually be a directory, not necessarily a file). So you can do this:

string parentDirectoryName = Path.GetFileName(Path.GetDirectoryName(fullPath));

I'm sure this is more efficient than my answer. – itsme86 Mar 03 '17 at 19:48
@itsme86, probably, because it never actually accesses the file system, it's just string manipulation. – Thomas Levesque Mar 03 '17 at 19:49

@itsme86 whether it is or it isn't, I'd say yours is a hell of a lot more readable ;) Not that this one is bad, but... – sab669 Mar 03 '17 at 19:55

@hatchet right, thanks for pointing it out – Thomas Levesque Mar 03 '17 at 22:23

There is more than one way to achieve your task.

solution 1:

var result = Path.GetFileName(Path.GetDirectoryName("Enter Path here"));

solution 2:

FileInfo info = new FileInfo("Enter Path here");   
String getDirectoryName = info.Directory.Name;

Yes, but OP wants just the name of the parent directory, not the full path – Thomas Levesque Mar 03 '17 at 19:47

You can use FileInfo to do it.

var fileInfo = new FileInfo(fileWithPath);
var parentName = fileInfo.Directory.Name;
