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 :)

我将接受的答案改编为。net Core，使用推荐的替换已弃用类:

腰椎->腰椎 ->工具箱

Program.cs

namespace TrayOnlyWinFormsDemo
{
    internal static class Program
    {
        [STAThread]
        static void Main()
        {
            ApplicationConfiguration.Initialize();
            Application.Run(new MyCustomApplicationContext());
        }
    }
}

MyCustomApplicationContext.cs

using TrayOnlyWinFormsDemo.Properties;  // Needed for Resources.AppIcon

namespace TrayOnlyWinFormsDemo
{
    public class MyCustomApplicationContext : ApplicationContext
    {
        private NotifyIcon trayIcon;

        public MyCustomApplicationContext()
        {
            trayIcon = new NotifyIcon()
            {
                Icon = Resources.AppIcon,
                ContextMenuStrip = new ContextMenuStrip()
                {
                    Items = { new ToolStripMenuItem("Exit", null, Exit) }
                },
                Visible = true
            };
        }

        void Exit(object? sender, EventArgs e)
        {
            trayIcon.Visible = false;
            Application.Exit();
        }
    }
}

简单的添加

this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;

到你的表单对象。 你只会在系统托盘上看到一个图标。

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.

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;
        }
    }
}
