What do I need to do to make a Windows Forms application to be able to run in the System Tray?

不是可以最小化到托盘的应用，而是只会存在于托盘中的应用，无外乎

Not an application that can be minimized to the tray, but an application that will be only exist in the tray, with nothing more than

• 工具提示，以及
• 右键单击"；菜单.

推荐答案

代码项目文章 CreatingTasktray Application 给出了一个非常简单的解释和示例，用于创建一个只存在于系统托盘中的应用程序.

The code project article Creating a Tasktray Application gives a very simple explanation and example of creating an application that only ever exists in the System Tray.

基本上更改 Program.cs 中的 Application.Run(new Form1()); 行，改为启动一个继承自 ApplicationContext 的类code>，并让该类的构造函数初始化一个 NotifyIcon

Basically change the Application.Run(new Form1()); line in Program.cs to instead start up a class that inherits from ApplicationContext, and have the constructor for that class initialize a NotifyIcon

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new MyCustomApplicationContext());
    }
}


public class MyCustomApplicationContext : ApplicationContext
{
    private NotifyIcon trayIcon;

    public MyCustomApplicationContext ()
    {
        // Initialize Tray Icon
        trayIcon = new NotifyIcon()
        {
            Icon = Resources.AppIcon,
            ContextMenu = new ContextMenu(new MenuItem[] {
                new MenuItem("Exit", Exit)
            }),
            Visible = true
        };
    }

    void Exit(object sender, EventArgs e)
    {
        // Hide tray icon, otherwise it will remain shown until user mouses over it
        trayIcon.Visible = false;

        Application.Exit();
    }
}
