在。net 6中，我必须像这样工作我的类的核心:

private NotifyIcon trayIcon;
private ContextMenuStrip contextMenu1;
private ToolStripMenuItem menuItem1;

public MyCustomApplicationContext()
{
    contextMenu1 = new System.Windows.Forms.ContextMenuStrip();
    menuItem1 = new System.Windows.Forms.ToolStripMenuItem();
    this.menuItem1.Text = "E&xit";
    this.menuItem1.Click += new System.EventHandler(Exit);
    this.contextMenu1.Items.AddRange(
            new System.Windows.Forms.ToolStripMenuItem[] {this.menuItem1 });
    trayIcon = new NotifyIcon(){Icon = Resources.AppIcon, ContextMenuStrip = this.contextMenu1, Visible = true };            

}

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 :)

据我所知，您仍然必须使用表单编写应用程序，但在表单上没有控件，并且永远不会将其设置为可见。使用NotifyIcon(可以在这里找到它的MSDN示例)来编写应用程序。

“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();
} 

您可以创建表单，修改它，然后将它传递给应用程序。作为参数运行。：

    internal static class Program
    {
        /// <summary>
        ///  The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            ApplicationConfiguration.Initialize();
            var form = new Form1();
            form.Hide();
            form.Opacity = 0;
            form.ShowInTaskbar = false;
            Application.Run(form);
        }
    }

添加你的通知图标和上下文菜单(如果需要)到你的表单在设计时作为一个常规的应用程序。确保你的通知图标是可见的，并有一个相关的图标。这还将允许您使用以后可能出于任何原因需要的表单

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);
