添加菜单按钮

 //创建好一个父菜单
            BarSubItem barSubItem = new BarSubItem(this.barManager1, "用户管理");
            bar2.InsertItem(bar2.ItemLinks[bar2.ItemLinks.Count - 1], barSubItem);

            //创建一个二级菜单
            BarItem barSmallItem = new BarButtonItem(this.barManager1, "增加用户");
            barSubItem.AddItem(barSmallItem);
