      {        
         Application.EnableVisualStyles();         
         Application.SetCompatibleTextRenderingDefault(false);         
         NotifyIcon notifyIcon1 = new NotifyIcon();                
         ContextMenu contextMenu1 = new ContextMenu();        
         MenuItem menuItem1 = new MenuItem();
         contextMenu1.MenuItems.AddRange(new MenuItem[] { menuItem1 });
         menuItem1.Index = 0;
         menuItem1.Text = "E&xit";
         menuItem1.Click += new EventHandler(menuItem1_Click);
         notifyIcon1.Icon = new Icon("app.ico");
         notifyIcon1.Text = "Form1 (NotifyIcon example)";
         notifyIcon1.ContextMenu = contextMenu1;
         notifyIcon1.Visible = true;         Application.Run();
         notifyIcon1.Visible = false;
      }
      private static void menuItem1_Click(object Sender, EventArgs e)
      {         Application.Exit();
      }
