2nd to last level of a directory tree

I am trying to get the 2nd to last level of the directory tree that I used an array to get. When it gets to the Console.WriteLine part, it doesn't display anything, it seems to skip that entire line.

foreach (string file in files)   
{   
    string thepathoflife = Path.GetFullPath(file);
    string filetocopy = file;
    string location = file;
    bool b = false;
    string extension = Path.GetExtension(file);
    string thenameofdoom = Path.GetFileNameWithoutExtension(file);
    string filename = Path.GetFileName(file);


    //here is my attempt
    string dirthing = Path.GetDirectoryName(filename); //here is my attempt
    System.Console.WriteLine("" + dirthing); //here is my attempt

Here are a few examples:

var path = Path.GetFullPath("example.png");
// path == "C:\\Users\\dtb\\Desktop\\example.png"

Path.GetFileName(path)                              // "example.png"
Path.GetFileNameWithoutExtension(path)              // "example"
Path.GetExtension(path)                             // ".png"

Path.GetDirectoryName(Path.GetFileName(path))       // ""

Path.GetDirectoryName(path)                         // "C:\\Users\\dtb\\Desktop"
Path.GetDirectoryName(Path.GetDirectoryName(path))  // "C:\\Users\\dtb"

You can call Path.GetDirectoryName twice to walk up the folder hierarchy:

Path.GetDirectoryName(Path.GetDirectoryName(Path.GetFullPath(file)))

It will return null if you are too "high" in the hierarchy.
