notifyIcon1->ContextMenu = gcnew

System::Windows::Forms::ContextMenu();
System::Windows::Forms::MenuItem^ nIItem = gcnew

nIItem->Click += gcnew System::EventHandler(this, &your_class::Open_NotifyIcon);

notifyIcon1->ContextMenu->MenuItems->Add(nIItem);

I've wrote a traybar app with .NET 1.1 and I didn't need a form. First of all, set the startup object of the project as a Sub Main, defined in a module. Then create programmatically the components: the NotifyIcon and ContextMenu. Be sure to include a MenuItem "Quit" or similar. Bind the ContextMenu to the NotifyIcon. Invoke Application.Run(). In the event handler for the Quit MenuItem be sure to call set NotifyIcon.Visible = False, then Application.Exit(). Add what you need to the ContextMenu and handle properly :)

notifyIcon1->ContextMenu = gcnew

System::Windows::Forms::ContextMenu();
System::Windows::Forms::MenuItem^ nIItem = gcnew
System::Windows::Forms::MenuItem("Open");

nIItem->Click += gcnew System::EventHandler(this, &your_class::Open_NotifyIcon);

notifyIcon1->ContextMenu->MenuItems->Add(nIItem);

正如mat1t所说，你需要在你的应用程序中添加一个NotifyIcon，然后使用下面的代码来设置工具提示和上下文菜单:

this.notifyIcon.Text = "This is the tooltip";
this.notifyIcon.ContextMenu = new ContextMenu();
this.notifyIcon.ContextMenu.MenuItems.Add(new MenuItem("Option 1", new EventHandler(handler_method)));

这段代码只显示了系统托盘中的图标:

this.notifyIcon.Visible = true;  // Shows the notify icon in the system tray

如果你有一个表格(无论出于什么原因)，以下将是需要的:

this.ShowInTaskbar = false;  // Removes the application from the taskbar
Hide();

右键点击获得上下文菜单是自动处理的，但如果你想在左键点击上做一些操作，你需要添加一个点击处理程序:

    private void notifyIcon_Click(object sender, EventArgs e)
    {
        var eventArgs = e as MouseEventArgs;
        switch (eventArgs.Button)
        {
            // Left click to reactivate
            case MouseButtons.Left:
                // Do your stuff
                break;
        }
    }

“系统托盘”应用程序只是一个普通的win表单应用程序，唯一的区别是它在windows系统托盘区域创建了一个图标。为了创建sys。托盘图标使用NotifyIcon组件，你可以在工具箱(常用控件)中找到它，并修改它的属性:图标，工具提示。它还允许您处理鼠标单击和双击消息。

还有一件事，为了实现外观和感觉或标准托盘应用程序。添加followinf行在你的主窗体显示事件:

private void MainForm_Shown(object sender, EventArgs e)
{
    WindowState = FormWindowState.Minimized;
    Hide();
} 

Create a new Windows Application with the wizard. Delete Form1 from the code. Remove the code in Program.cs starting up the Form1. Use the NotifyIcon class to create your system tray icon (assign an icon to it). Add a contextmenu to it. Or react to NotifyIcon's mouseclick and differenciate between Right and Left click, setting your contextmenu and showing it for which ever button (right/left) was pressed. Application.Run() to keep the app running with Application.Exit() to quit. Or a bool bRunning = true; while(bRunning){Application.DoEvents(); Thread.Sleep(10);}. Then set bRunning = false; to exit the app.
