C # WinForm window minimized to system tray _c# Tutorial

1. Set WinForm Form Properties Showintask=false
2. Add the NotifyIcon control NotifyIcon1, adding an icon icon for the property icon of the control NotifyIcon1.
3. Add form Minimize event (you need to add an event reference first):

Copy Code code as follows:

This. SizeChanged + = new System.EventHandler (this. form1_sizechanged);
The above line is the reference that needs to be added in the main form InitializeComponent () method
private void Form1_sizechanged (object sender, EventArgs e)
{
if (this. WindowState = = formwindowstate.minimized)
{
This. Hide ();
This.notifyicon1.visible=true;
}
}

4. Add Click Icon Event (first need to add Event reference):
private void Notifyicon1_click (object sender, EventArgs e)
{
This. Visible = true;
This. WindowState = Formwindowstate.normal;
This.notifyIcon1.Visible = false;
}
5. You can add the right button menu to NotifyIcon:
Drag a ContextMenu control nicontextmenu the main form, click the Control, add a menu to the context menu, and select Nicontextmenu as the context menu in the ContextMenu behavior of the notifyIcon1.

Copy Code code as follows:

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);
