How do I extract each folder name from a path if I don't know how many folders there are in the path and I don't know the folder names?

Do you want it to be recursivem or just in that path - As in, do you want subfolders too? — Peter Rasmussen, Jul 15 '13 at 08:34

Split the string by using seprator:

var dirs[] = completePath.Split(Path.DirectorySeparatorChar);

after iterate over each subfolder and construct possible subpaths

var composition = string.Empty;
var directoryPathList = new List<string>();
foreach(var s in dirs) {
     composition += Path.DirectorySeparatorChar + s; 
     directoryPathList.Add(composition);         
}

You can just use String.Split:

string fileName = @"C:\foo\bar\baz.txt";
string directory = Path.GetDirectoryName(fileName); // "C:\foo\bar"
string allDirectoryNames = directory.Split('\\'); // ["C:", "foo", "bar"]

I'd use `System.IO.Path.DirectorySeparatorChar` instead of `'\\'`. – Nolonar Jul 15 '13 at 08:37

Do you mean something like this:

String path = @"\\MyNetwork\Test\my progs\MySource.cpp";

String[] names = Path.GetDirectoryName(path).Split(new Char[] {
    Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar}, StringSplitOptions.RemoveEmptyEntries);

// names contains ["MyNetwork", "Test", "my progs"]
