提问
WPF 如何添加系统托盘
回答
1.引入nuget 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
if (!IsVisible)
{
Show();
}
if (WindowState == WindowState.Minimized)
{
WindowState = WindowState.Normal;
}
Activate();
Topmost = true; // important
Topmost = false; // important
Focus(); // important
