I have a path like

string path = @"C:\foo\bar\temp\test\file.txt";

and want to get the foldername of the file - in this case the expected result is "test".

Is there a build in way which is more elegant compared to path.SubString(path.LastIndexOf('/') etc..

You have to use Path.GetDirectoryName (path);

string path = "C:/foo/bar/yourFile.txt";
string folderName = Path.GetFileName(Path.GetDirectoryName(path));

OR

string path = "C:/foo/bar/yourFile.txt";
string folderName = new DirectoryInfo(path).Name;

OR

string path = "C:/foo/bar/yourFile.txt";
string folderName = new FileInfo(path).Directory?.Name;

You can get the name of the file's parent directory by using the DirectoryInfo.Name:

new FileInfo(@"C:\foo\bar\temp\test\file.txt").Directory.Name

This will return 'test' from the example.

  • Well there's more or less the same answer there, just they load `DirectoryInfo` using a `DirectoryInfo(System.IO.Path.GetDirectoryName(filename))`, instead of loading through file. – Krypt1 Jun 04 '18 at 14:40

Use the static Path class:

Path.GetFileName(Path.GetDirectoryName(path))

You should use Path.GetDirectoryName() and then take Path.GetFileName().

This example returns what you asked for: 

var fileName = @"C:\foo\bar\temp\test\file.txt";
var directoryPath = Path.GetDirectoryName(fileName);
var directoryName = Path.GetFileName(directoryPath); 
Console.WriteLine(directoryName);

Result: test
