请教，怎么访问菜单控件的子项的子项

请问，如何访问菜单控件的子项的子项
如何访问菜单控件（MenuStrip）的子项的子项的子项.....
每个项的类型是ToolStripMenuItem类，子项又是什么类型的，也就是1级项。2级项又是什么类型，3级呢？
如何把某个2级子项设置为隐藏，比如对于非高级会员就可以隐藏某个2级子项。

C# code

        public void ShowControl(ToolStripItemCollection items)        {            foreach (ToolStripMenuItem item in items)            {                MessageBox.Show(item.Text);                if (item.DropDownItems.Count > 0)                {                    ShowControl(item.DropDownItems);                }            }        }        private void button1_Click(object sender, EventArgs e)        {            ShowControl(this.menuStrip1.Items);        }

新建一个窗体，添加2个按钮，button1 button2，编写如下代码：
C# code
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;namespace WindowsFormsApplication2{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {            MenuStrip ms = new MenuStrip();            ToolStripMenuItem tsmi = new ToolStripMenuItem("视图1");            ToolStripMenuItem tsmi1 = new ToolStripMenuItem("视图1-1");            ToolStripMenuItem tsmi11 = new ToolStripMenuItem("视图1-1-1");            ToolStripMenuItem tsmi12 = new ToolStripMenuItem("视图1-1-2");            ToolStripMenuItem tsmi13 = new ToolStripMenuItem("视图1-1-3");            tsmi1.DropDownItems.AddRange(new ToolStripItem[] { tsmi11, tsmi12, tsmi13 });            ToolStripMenuItem tsmi2 = new ToolStripMenuItem("视图1-2");            ToolStripMenuItem tsmi21 = new ToolStripMenuItem("视图1-2-1");            ToolStripMenuItem tsmi22 = new ToolStripMenuItem("视图1-2-2");            tsmi2.DropDownItems.AddRange(new ToolStripItem[] { tsmi21, tsmi22 });            ToolStripMenuItem tsmi3 = new ToolStripMenuItem("视图1-3");            ToolStripMenuItem tsmi31 = new ToolStripMenuItem("视图1-3-1");            tsmi3.DropDownItems.AddRange(new ToolStripItem[] { tsmi31 });            tsmi.DropDownItems.AddRange(new ToolStripItem[] { tsmi1, tsmi2, tsmi3 });            ms.Items.Add(tsmi);            ms.Dock = DockStyle.Top;            Controls.Add(ms);            MainMenuStrip = ms;        }        private IEnumerable<ToolStripMenuItem> GetAllMenuItems(ToolStripMenuItem top)        {            return top.DropDownItems.Cast<ToolStripMenuItem>().SelectMany(x => GetAllMenuItems(x)).Concat(top.DropDownItems.Cast<ToolStripMenuItem>());        }        private void button2_Click(object sender, EventArgs e)        {            foreach (ToolStripMenuItem item in (Controls.OfType<MenuStrip>().FirstOrDefault() ?? new MenuStrip()).Items)            {                foreach (ToolStripMenuItem subitem in GetAllMenuItems(item).Where(x => x.Text.Contains("3")))                {                    subitem.Enabled = false;                }            }        }    }}

本程序支持无线递归搜索，你可以尝试再添加更深层次的菜单。

在真实使用中，你可以精确搜索你要的菜单项目，代码如下：
var menu = GetAllMenuItems(Controls.OfType<MenuStrip>().FirstOrDefault().Items.Cast<ToolStripMenuItem>().Where(x => x.Text == "主菜单文本").FirstOrDefault()).Where(x => x.Text == "你要找的菜单的文本").FirstOrDefault();
menu.Visibled = false; //隐藏
menu.Enabled = false; //禁用
menu.DropDownItems.Add(new ToolStripMenuItem("xxx")); //添加子菜单 
 
... //任何你想要的操作
