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.

下面是我如何用Visual Studio 2010， .NET 4做到的

Create a Windows Forms Application, set 'Make single instance application' in properties Add a ContextMenuStrip Add some entries to the context menu strip, double click on them to get the handlers, for example, 'exit' (double click) -> handler -> me.Close() Add a NotifyIcon, in the designer set contextMenuStrip to the one you just created, pick an icon (you can find some in the VisualStudio folder under 'common7...') Set properties for the form in the designer: FormBorderStyle:none, ShowIcon:false, ShowInTaskbar:false, Opacity:0%, WindowState:Minimized Add Me.Visible=false at the end of Form1_Load, this will hide the icon when using Ctrl + Tab Run and adjust as needed.

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 :)

这是一个非常友好的框架通知区域应用程序…将NotificationIcon添加到基本表单并将自动生成的代码更改为下面的代码就足够了:

public partial class Form1 : Form
{
    private bool hidden = false;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.ShowInTaskbar = false;
        //this.WindowState = FormWindowState.Minimized;
        this.Hide();
        hidden = true;
    }

    private void notifyIcon1_Click(object sender, EventArgs e)
    {
        if (hidden) // this.WindowState == FormWindowState.Minimized)
        {
            // this.WindowState = FormWindowState.Normal;
            this.Show();
            hidden = false;
        }
        else
        {
            // this.WindowState = FormWindowState.Minimized;
            this.Hide();
            hidden = true;
        }
    }
}

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);
