How to organize the launch of the program immediately minimized to tray? Did collapse by clicking on the "Minimize" button:

private void notifyIcon1_MouseClick(object sender, MouseEventArgs e) { this.Show(); this.WindowState = FormWindowState.Normal; notifyIcon1.Visible = false; } private void Form1_Resize(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Minimized) { this.Hide(); notifyIcon1.Visible = true; } }

And how to organize, so that the application immediately appeared at the start of the tray, without displaying the form on the screen?

To do this, you mainly need to call Application.Run() without passing the form as a parameter to it.

If you want to have an icon in the tray, modify the Main method as follows (context menu is optional):

 static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); var form = new Form1(); using (NotifyIcon icon = new NotifyIcon()) { icon.Icon = Icon.ExtractAssociatedIcon(Application.ExecutablePath); icon.ContextMenu = new ContextMenu( new [] { new MenuItem("Show form", (s, e) => form.Show()), new MenuItem("Hide form", (s, e) => form.Hide()), new MenuItem("Exit", (s, e) => Application.Exit()), }); icon.Visible = true; Application.Run(); icon.Visible = false; } }

    Minimize the window in the form load handler.

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