wpf最小化关闭窗体

wpf如何最小化关闭窗体？

如下：

<Button Style="{StaticResource FormButtonStyle}" Click="FormMinimize">-</Button>
<Button Style="{StaticResource FormButtonStyle}" Click="FormClose">×</Button>      

private void FormMinimize(object sender, RoutedEventArgs e)
{
    WindowState = WindowState.Minimized;//最小化
}

private void FormClose(object sender, RoutedEventArgs e)
{
    Close();//关闭
}
