Try

public void LookingFor(DirectoryInfo dir)
{
   if (dir.Parent == null)
      return;
   // Add parent to ListView
   LookingFor(dir.Parent);
}

Take the path of the directory, and call the GetParent method. You can do this in a loop if need be and walk back up the directory tree:

string parentDir = Directory.GetParent("some path");
