TreeView and ListBox - Values ?

Question

Hi all

First timer here and a complete newbie heh..

I' jumped right in and are trying to learn C#, and i'v bin struggling whit a TreeView / ListBox solution the last couple of days and now i have to aske..  


This is how i Populate the Treeview:

 public void PopulateTreeView(string directoryValue, TreeNode parentNode)
        {
            try
            {
                DirectoryInfo directory = new DirectoryInfo(directoryValue);

                foreach (DirectoryInfo d in directory.GetDirectories())
                {
                    // Create Node
                    TreeNode t = new TreeNode(d.Name);

                    PopulateTreeView(d.FullName, t);
                    parentNode.Nodes.Add(t);
                }

                foreach (FileInfo f in directory.GetFiles("*.mp3"))
                {

                    TreeNode t = new TreeNode();
                    
                    t.Text = f.Name.ToString();
                    t.Tag = Path.GetFullPath(f.DirectoryName);

                    parentNode.Nodes.Add(t);
                }
            }
            catch (UnauthorizedAccessException)
            {
                parentNode.Nodes.Add("Access denied");
            }
        }

it's looking in a fixed directory (whit sub folders) for mp3 files.. this works.

now the big question from here..

I got a ListBox that has to become the playlist, sow i got button to add a selected TreeView Node over to ListBox
as you can see above i have a t.Text and a t.Tag, t.text holde the file name and t.Tag the FullPath

how do i get Text and FullPath into my ListBox as a Item ? i hav tryed DisplayMember and ValueMember :

            lbPlaylist.DisplayMember = tvMedia.SelectedNode.Text;
            lbPlaylist.ValueMember = Convert.ToString(tvMedia.SelectedNode.Tag);

lbPlaylist is the ListBox

can anyone of you help here ? 

is ther i a better way ?  

and please.. remember im a complete newbie :)
