            TreeNode newSelected = e.Node;
            string str = newSelected.Text;
            if (str == "我的电脑")
                return;
            listView1.Items.Clear();
            DirectoryInfo nodeDirInfo = (DirectoryInfo)newSelected.Tag;
            ListViewItem.ListViewSubItem[] subItems;
            ListViewItem item = null;
            try
            {
                foreach (FileInfo file in nodeDirInfo.GetFiles())
                {                    item = new ListViewItem(file.FullName);
                    subItems = new ListViewItem.ListViewSubItem[]
                        { new ListViewItem.ListViewSubItem(item, "文件"), 
                            new ListViewItem.ListViewSubItem(item, 
                            file.LastAccessTime.ToShortDateString())};
