c# - 将应用程序最小化到系统托盘

Question

我有一个由 C# 和 Visual Studio 2010 提供支持的 Windows 窗体应用。

如何将我的应用程序最小化到系统托盘(不是任务栏)，然后在双击系统托盘时将其恢复？任何想法？另外，我怎样才能在系统托盘的图标中制作一些菜单，当我右键单击它时，它会显示一个菜单，如登录、断开连接、连接等。 还有，有什么方法可以让系统托盘弹出气球？

PS:我已经添加了notifyIcon，但是不知道怎么用。

• C# System Tray Minimize To Tray With NotifyIcon
• Minimize window to system tray

Handle the form’s Resize event. In this handler, you override the basic functionality of the Resize event to make the form minimize to the system tray and not to the taskbar. This can be done by doing the following in your form’s Resize event handler: Check whether the form’s WindowState property is set to FormWindowState.Minimized. If yes, hide your form, enable the NotifyIcon object, and show the balloon tip that shows some information. Once the WindowState becomes FormWindowState.Normal, disable the NotifyIcon object by setting its Visible property to false. Now, you want the window to reappear when you double click on the NotifyIcon object in the taskbar. For this, handle the NotifyIcon’s MouseDoubleClick event. Here, you show the form using the Show() method.

private void frmMain_Resize(object sender, EventArgs e)
{
    if (FormWindowState.Minimized == this.WindowState)
    {
       mynotifyicon.Visible = true;
       mynotifyicon.ShowBalloonTip(500);
       this.Hide();
    }

    else if (FormWindowState.Normal == this.WindowState)
    {
       mynotifyicon.Visible = false;
    }
}
