C # writes The Window appllication that is hidden as the taskbar icon when minimized.

1. Set WinForm Form Properties Showintask=false

2. Add NotifyIcon control NotifyIcon1, adding an icon to the property icon for the control NotifyIcon1.

3. Add a form Minimize event (you need to add an event reference first):

This. SizeChanged + = new System.EventHandler (this. form1_sizechanged);

private void Form1_sizechanged (object sender, EventArgs e)
{
if (this. WindowState = = formwindowstate.minimized)
{
This. Hide ();
This.notifyicon1.visible=true;
}
}

4. Add a click Icon event (you need to add an event reference first):

private void Notifyicon1_click (object sender, EventArgs e)
{
This. Visible = true;
This. WindowState = Formwindowstate.normal;
This.notifyIcon1.Visible = false;
}

5. You can add a right-click menu to NotifyIcon:

Drag the main form into a ContextMenu control Nicontextmenu, click the control in the context menu, add a menu to the NotifyIcon1 contextmenu behavior, and select Nicontextmenu as the context menu.

This.notifyicon1 = new System.Windows.Forms.NotifyIcon (this.components);
This. Nicontextmenu = new System.Windows.Forms.ContextMenu ();
This.menuitem_hide = new System.Windows.Forms.MenuItem ();
This.menuitem_show = new System.Windows.Forms.MenuItem ();
This.menuitem_aubot = new System.Windows.Forms.MenuItem ();
This.menuitem_exit = new System.Windows.Forms.MenuItem ();


This.notifyIcon1.ContextMenu = this. Nicontextmenu;
This.notifyIcon1.Icon = ((System.Drawing.Icon) (resources. GetObject ("Notifyicon.icon"));
This.notifyIcon1.Text = "";
This.notifyIcon1.Visible = true;
This.notifyIcon1.DoubleClick + = new System.EventHandler (This.notifyicon1_doubleclick);
This.notifyIcon1.Click + = new System.EventHandler (This.notifyicon1_click);


This. NicontextMenu.MenuItems.AddRange (

New system.windows.forms.menuitem[]
{
This.menuitem_hide,
This.menuitem_show,
This.menuitem_aubot,
This.menuitem_exit
}
);

//
Menuitem_hide
//
This.menuItem_Hide.Index = 0;
This.menuItem_Hide.Text = "hidden";
This.menuItem_Hide.Click + = new System.EventHandler (This.menuitem_hide_click);
//
Menuitem_show
//
This.menuItem_Show.Index = 1;
This.menuItem_Show.Text = "Display";
This.menuItem_Show.Click + = new System.EventHandler (This.menuitem_show_click);
//
Menuitem_aubot
//
This.menuItem_Aubot.Index = 2;
This.menuItem_Aubot.Text = "about";
This.menuItem_Aubot.Click + = new System.EventHandler (This.menuitem_aubot_click);
//
Menuitem_exit
//
This.menuItem_Exit.Index = 3;
This.menuItem_Exit.Text = "Exit";
This.menuItem_Exit.Click + = new System.EventHandler (This.menuitem_exit_click);
