menuStrip1动态添加菜单及快捷键

     public partial class FormMkTest : Form
     {
         public FormMkTest()
         {
             InitializeComponent();
         }

         private void FormMkTest_Load(object sender, EventArgs e)
         {
             //添加菜单一文本中加入 &F  即ALT+F  打开某子菜单
             ToolStripMenuItem subItem;
             subItem = AddContextMenu("文件(&F)", menuStrip1.Items, null);
             //添加子菜单
             AddContextMenu("打开(&O)", subItem.DropDownItems, new EventHandler(MenuClicked));
             AddContextMenu("下载(&D)", subItem.DropDownItems, new EventHandler(MenuClicked));

             //添加菜单二
             subItem = AddContextMenu("&Edit", menuStrip1.Items, null);
             //添加子菜单
             ToolStripMenuItem Grandson = AddContextMenu("&Update", subItem.DropDownItems, new EventHandler(MenuClicked));
             //孙子
             AddContextMenu("孙子级", Grandson.DropDownItems, new EventHandler(MenuClicked));
             AddContextMenu("-", subItem.DropDownItems, null);//增加一个分割线
             AddContextMenu("没有快捷键", subItem.DropDownItems, new EventHandler(MenuClicked));

         }
         /// <summary>
         /// 添加子菜单
         /// </summary>
         /// <param name="text">要显示的文字，如果为 - 则显示为分割线</param>
         /// <param name="cms">要添加到的子菜单集合即</param>
         /// <param name="callback">点击时触发的事件</param>
         /// <returns>生成的子菜单，即该级的下一级如果为分隔条则返回null</returns>

         ToolStripMenuItem AddContextMenu(string text, ToolStripItemCollection cms, EventHandler callback)
         {
             if (text == "-")
             {
                 ToolStripSeparator tsp = new ToolStripSeparator();
                 cms.Add(tsp);
                 return null;
             }
             else if (!string.IsNullOrEmpty(text))
             {
                 ToolStripMenuItem tsmi = new ToolStripMenuItem(text);
                 tsmi.Tag = text + "TAG";
                 if (callback != null) tsmi.Click += callback;
                 cms.Add(tsmi);

                 return tsmi;
             }

             return null;
         }
         void MenuClicked(object sender, EventArgs e)
         {
             //以下主要是动态生成事件并打开窗体

             //((sender as ToolStripMenuItem).Tag)强制转换

             //ObjectHandle t = Activator.CreateInstance("WinForms", "WinForms.Form2");
             //Form f = (Form)t.Unwrap();
             //f.ShowDialog();
             string s = (sender as ToolStripMenuItem).Text;
             MessageBox.Show(s);
         }
     }

　附加一字符串处理：

            string mStr = "武藤兰(&F)";
            string mStred = Regex.Replace(mStr, "\\(&.?\\)", "");
            Console.Write(mStred);
