怎么生成菜单的分隔符？

Question

我是用toolstripmenuitem来定义右键菜单项的，我想不同类型的菜单都用长线区分开来，我这么实例化菜单项的new ToolStripMenuItem("-")，发现不对  

Answer 1

                ToolStripItem[] new_added_menu_items = {
                                                           new ToolStripMenuItem("-"),
                                                           new ToolStripMenuItem("定位户", null,
                                                                                 btn_locate_in_geometry_Click),
                                                           new ToolStripMenuItem("鼠标获取地理位置", null,
                                                                                 btn_mouse_get_geom_Click),
                                                           new ToolStripMenuItem("手动设置地理位置", null, btn_edit_geom_Click)
                                                       };
                menu_items_list.AddRange(new_added_menu_items);                right_menu.Items.Clear();
                right_menu.Items.AddRange(menu_items_list.ToArray());                right_menu.Show(Control.MousePosition);
