　　 7、form2.Owner = this //设置拥有此窗体的窗体，this代表主窗体附属窗体随主窗体的显示而显示

　　 form2.ShowInTaskbar = false

　　 form2.Show()

　　 8、Form1 formmain = new Form1() //form2的窗体关闭并显示form1窗体

　　 formmain = (Form1)this.Owner //将全局变量this.Owner强制转换给FormMain类型-C# system tray program source code examples and knowledge points: 1, add a NotifyIcon component and a ContextMenuStrip component to the main form 2, set the control' s ContextMenuStrip property notifyIcon1 contextMenuStrip1, the user clicks on the tray icon to display a menu point contextMenuStrip1 3, notifyIcon1 .
