C#: How to add text (ex creation time) to my folders in my treeview.

Question

Hello

I am making an application where you in a form have a treeview of folders. If you click on one of the folders in the treeview you get directed to a new form with a new treeview containing the files in the chosen folder. Please forgive my inexperienced programming. We all have to start somewhere ;)

This is code from my first form.

            DirectoryInfo di = new DirectoryInfo("c:/ProjektTest/");
            DirectoryInfo[] folders = di.GetDirectories();

            ArrayList folderArray = new ArrayList();

            foreach (DirectoryInfo d in folders)
            {
                TreeNode aFolder = new TreeNode(d.ToString());
                aFolder.Tag = folderArray;
                folderArray.Add(new ListViewItem(aFolder.Text));
                treeView1.Nodes.Add(aFolder);
            }

Now my folders are listed. Next I need to list my files (*.smp) in the treeview on form 2 (myFiles).

                folderPath = new DirectoryInfo("c:/ProjektTest/" + treeView1.SelectedNode.FullPath.ToString());
                FileInfo[] rgFile = folderPath.GetFiles("*.smp");

                foreach (FileInfo f in rgFile)
                {
                    folderAndNodePath = new DirectoryInfo(folderPath.ToString());
                    ArrayList fileArray = new ArrayList();
                    aFile = new TreeNode(f.ToString());
                    aFile.Tag = fileArray;
                    fileArray.Add(new ListViewItem(aFile.Text));
                    myFiles.treeView2.Nodes.Add(aFile);
                }

If I change the text in my treeview - add creation time or something like that - the application will crash since the given path is now wrong and it is used in a method call to read the contant of the files. The added text will also be added to the path - hence the error.
I've tried setting aFile.Name and afterwards using this when setting the path. But if I put this in my foreach statement the name will always be the last file in my folder.
I am not sure how to work around this. Can you help me out?

Thank you!

It seems I handled my problem. I've saved all file names in an ArrayList. After this I can alter the text in my nodes. When i then need a path for the chosen file I simply get the file name in my ArrayList.

FileNames[treeView1.SelectedNode.Index].ToString()

I dont know if there is a better way to do it, but this worls - for now :P

Thank you for your  time.
