  if （Treeviewitem.Items.Count ==  1 && Treeviewitem.Items [  0 ] == dummyNode）
 {
 Treeviewitem.Items.Clear（）; 
 尝试 
 {
  foreach （ string  s  in  Directory.GetDirectories（Treeviewitem.Tag.ToString（）））
 {
 TreeViewItem Treeviewsubitem =  new  TreeViewItem（）; 
 Treeviewsubitem.Header = s.Substring（s.LastIndexOf（  \\ ）+  1 ）; 
 Treeviewsubitem.Tag = s; 
 Treeviewsubitem.FontWeight = FontWeights.Normal; 
 Treeviewsubitem.Items.Add（dummyNode）; 
 Treeviewsubitem.Expanded + =  new  RoutedEventHandler（folder_Expanded）;

            if (Treeviewitem.Items.Count == 1 && Treeviewitem.Items[0] == dummyNode)
            {
