WPF 添加系統托盤

提問

WPF 如何添加系統托盤

回答

1.引入nuget handycontrol
cs xmlns:hc="https://handyorg.github.io/handycontrol"
2.窗體添加控件
cs <hc:NotifyIcon x:Name="NotifyIconContextContent" Text="軟件名稱" ContextMenu="{StaticResource ContextMenu}" Click="NotifyIconContextContent_Click"> </hc:NotifyIcon>
3.最小化隱藏窗體
cs private void btnMinimize_Click(object sender, RoutedEventArgs e) { WindowState = WindowState.Minimized; ShowInTaskbar = false; }
4.單機托盤顯示窗體

 if (!IsVisible)
 {
     Show();
 }

 if (WindowState == WindowState.Minimized)
 {
     WindowState = WindowState.Normal;
 }

 Activate();
 Topmost = true;  // important
 Topmost = false; // important
 Focus();         // important
