csdn上铅消的例子 （仅供参考槐镇知）旅梁： private void treeView1_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs e) { TreeViewItem item = (TreeViewItem)treeView1.SelectedItem; TreeViewItem it = new TreeViewItem(); if (!item.HasItems) { if (item.Parent != null && (item.Parent is TreeViewItem)) { it = (TreeViewItem)item.Parent; MessageBox.Show(it.Header.ToString() + (item.Parent is TreeViewItem).ToString()); } else { MessageBox.Show(item.Header.ToString()); } } }
