下面是该类的具体实现：

using System;using System.Linq;using System.Collections.Generic;using System.Collections;using System.Text;using System.ComponentModel;using System.Windows.Forms;namespace LPGMobileDevice{    class PanelMenu    {        private Panel panel;        public Panel Panel        {            get { return panel; }                   }        private MainMenu menu;        public MainMenu Menu        {            get { return menu; }                    }        private MenuItem mi_Main, mi_Exit;        public MenuItem Mi_Main        {            get { return mi_Main; }        }        public MenuItem Mi_Exit        {            get { return mi_Exit; }                    }        public PanelMenu()        {            panel = new Panel();            //System.Drawing.Point point=new System.Drawing.Point(0,0);            //panel.Location = point;            System.Drawing.Size size = new System.Drawing.Size(240, 25);            panel.Size = size;            menu = new MainMenu();            mi_Main = new MenuItem();            mi_Main.Text = "主页";            mi_Exit = new MenuItem();            mi_Exit.Text = "退出";            menu.MenuItems.Add(mi_Main);            menu.MenuItems.Add(mi_Exit);            mi_Main.Click += new EventHandler(Main);            mi_Exit.Click+=new EventHandler(Exit);        }        private void Main(object sender, EventArgs e)        {            MainForm mf = new MainForm();            mf.ShowDialog();        }        private void Exit(object sender, EventArgs e)        {            //Application.Exit();            System.Diagnostics.Process.GetCurrentProcess().Kill();        }            }}

在其他窗体中调用：

PanelMenu pm = new PanelMenu();            this.Menu = pm.Menu;            this.Controls.Add(pm.Panel);

 

代码重用能减少大量的控件拖拽和事件的编写。

但我感觉还是有更方便使用的方法，望各位指导！
