WPF 如何添加系统托盘

1.使用Nuget 添加 handycontrol

cs xmlns:hc="https://handyorg.github.io/handycontrol"

2.窗体添加控件
cs <hc:NotifyIcon x:Name="NotifyIconContextContent" Text="软件名称" ContextMenu="{StaticResource ContextMenu}" Click="NotifyIconContextContent_Click"> </hc:NotifyIcon>

3.最小化隐藏窗体
cs private void btnMinimize_Click(object sender, RoutedEventArgs e) { WindowState = WindowState.Minimized; ShowInTaskbar = false; }

4.单机托盘显示窗体

cs 复制代码

 if (!IsVisible)
 {
     Show();
 }

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

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