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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 | 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(); } |
