C# WinForm 用MenuStrip动态生成菜单并动态加载事件

最近在做WINFORM开发,一直都在为主界面的点击事件及动态加载菜单苦脑。现在已解决这个问题了,可以实现数据库或都XML等配置完成动态生成菜单及事件加载。代码如下:

private void Form1_Load(object sender, EventArgs e)

        {

            //添加菜单一 

            ToolStripMenuItem subItem;

            subItem = AddContextMenu("入库", menuStrip1.Items, null);

            //添加子菜单 

            AddContextMenu("添加入库", subItem.DropDownItems, new EventHandler(MenuClicked));

            AddContextMenu("入库管理", subItem.DropDownItems, new EventHandler(MenuClicked));



            //添加菜单二 

            subItem = AddContextMenu("出库", menuStrip1.Items, null);

            //添加子菜单 

            AddContextMenu("添加出库", subItem.DropDownItems, new EventHandler(MenuClicked));

            AddContextMenu("出库管理", 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</param>

        /// <param name="callback">点击时触发的事件</param>

        /// <returns>生成的子菜单,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();



        }
