为控件创建右键菜单栏

 

主要步骤有三：

创建需要支持右键 的控件

定义菜单栏

核心 为控件添加菜单栏

整个过程在窗体的构造函数中实现，也就是designer.cs中的InitializeComponent方法

this.contextMenuStrip1 = new System.Windows.Forms.ContextMenuStrip(this.components);//支持右键 的控件

 System.Windows.Forms.ContextMenu notifycontextMenu = new System.Windows.Forms.ContextMenu();//右键菜单栏

 this.notifyIcon1.ContextMenu = notifycontextMenu;//添加菜单栏到指定控件

有以上代码就已经实现了右键菜单，要丰富菜单内容则需要如下代码，不做细说：

 System.Windows.Forms.MenuItem menuItem_Hide = new System.Windows.Forms.MenuItem();
            System.Windows.Forms.MenuItem menuItem_Show = new System.Windows.Forms.MenuItem();
            System.Windows.Forms.MenuItem menuItem_Aubot = new System.Windows.Forms.MenuItem();
            System.Windows.Forms.MenuItem menuItem_Exit = new System.Windows.Forms.MenuItem();

 menuItem_Hide.Index = 0;
            menuItem_Hide.Text = "隐藏 ";
            menuItem_Hide.Click += new System.EventHandler(this.menuItem_Hide_Click);
            //    
            //       menuItem_Show
            //    
            menuItem_Show.Index = 1;
            menuItem_Show.Text = "显示 ";
            menuItem_Show.Click += new System.EventHandler(this.menuItem_Show_Click);
            //    
            //       menuItem_Aubot
            //    
            menuItem_Aubot.Index = 2;
            menuItem_Aubot.Text = "关于 ";
            menuItem_Aubot.Click += new System.EventHandler(this.menuItem_Aubot_Click);
            //    
            //       menuItem_Exit
            //    
            menuItem_Exit.Index = 3;
            menuItem_Exit.Text = "退出 ";
            menuItem_Exit.Click += new System.EventHandler(this.menuItem_Exit_Click);

            notifycontextMenu.MenuItems.AddRange( new System.Windows.Forms.MenuItem[]{
          menuItem_Hide,
          menuItem_Show,
          menuItem_Aubot,
          menuItem_Exit
    }
          );

然后自己在窗体后台代码中添加menuItem_Aubot_Click等函数定义点击事件处理函数。
