Windows 10 个桌面应用程序的自定义标题栏颜色

Question

我在 Windows 10 上有一个混合 WinForms/WPF 桌面应用程序运行，它仍然以 .NET 3.5 为目标。它有白天模式、dusk 模式和夜间模式。在夜间模式下，一切基本上都是黑底红字，但标题栏仍然默认为白色。

在“设置”>“个性化”>“颜色”>“在以下表面上显示强调色”中，您可以选中“标题栏”并获取要用于标题栏的强调色，然后选择深色。但是，并非我们所有的用户都知道此设置。

是否有一种简单的方法可以通过编程更改从应用程序创建的所有 Windows 的标题栏背景和前景色？如果需要，我可以使用 p/Invoke。

如果没有，我也会接受一种以编程方式全局更改标题栏颜色的方法（系统上所有 Windows），甚至可以提供自动选中该框的方法（标题上的强调色）条）并设置深色强调色。

编辑：可以不用设置 WindowStyle="None" 和 custom-implement 标题栏吗？这就是我已经（厌倦了）做的事情。

在 WPF（我假设是 WinForms）中，创建无边框 window 和自己创建标题栏更容易。这是执行此操作的 WPF 代码,

首先是 C#：

public partial class MainWindow : Window, INotifyPropertyChanged
{
    public MainWindow()
    {
        InitializeComponent();            
    }

    public event PropertyChangedEventHandler PropertyChanged;
    private void Notify(params string[] PropertyNames)
    {
        foreach (string PropertyName in PropertyNames)
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(PropertyName));
    }

    public Visibility CanMaximize { get { return WindowState == WindowState.Normal ? Visibility.Visible : Visibility.Collapsed;  } }
    public Visibility CanRestore { get { return WindowState == WindowState.Maximized ? Visibility.Visible : Visibility.Collapsed; } }

    private void CloseWindow(object sender, ExecutedRoutedEventArgs e)
    {
        Application.Current.Shutdown();
    }

    private void CanExecute(object sender, CanExecuteRoutedEventArgs e)
    {
        e.CanExecute = true;            
    }

    private void MinimizeWindow(object sender, ExecutedRoutedEventArgs e)
    {
        this.WindowState = WindowState.Minimized;            
    }

    private void MaximizeWindow(object sender, ExecutedRoutedEventArgs e)
    {
        this.WindowState = WindowState.Maximized;
        Notify("CanMaximize", "CanRestore");
    }

    private void RestoreWindow(object sender, ExecutedRoutedEventArgs e)
    {
        this.WindowState = WindowState.Normal;
        Notify("CanMaximize", "CanRestore");
    }

    private void TitleBar_MouseMove(object sender, MouseEventArgs e)
    {
        if (Mouse.LeftButton == MouseButtonState.Pressed)            
        {
            if (TitleBar.IsMouseDirectlyOver)
                DragMove();
        }
    }

}

现在 XAML:

<Window x:Class="WpfApp1.MainWindow"

    <DockPanel DockPanel.Dock="Top" Background="#FF000020" x:Name="TitleBar" MouseMove="TitleBar_MouseMove">
        <Image DockPanel.Dock="Left" Source="{Binding ElementName=root, Path=Icon}" Stretch="Uniform" Height="25" Width="25" Margin="2,0"/>
        <Button Command="SystemCommands.CloseWindowCommand" DockPanel.Dock="Right" Margin="0" Padding="0">
            <Grid Width="25" Height="25" Background="{Binding ElementName=TitleBar, Path=Background}">
                <TextBlock  Text="&#xE10A;" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="White" />
            </Grid>
        </Button>
        <Button Command="SystemCommands.RestoreWindowCommand" DockPanel.Dock="Right" Visibility="{Binding ElementName=root, Path=CanRestore}">
            <Grid Width="25" Height="25" Background="{Binding ElementName=TitleBar, Path=Background}">
                <TextBlock  Text="&#xE158;" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="White" />
            </Grid>
        </Button>
        <Button Command="SystemCommands.MaximizeWindowCommand" DockPanel.Dock="Right" Visibility="{Binding ElementName=root, Path=CanMaximize}">
            <Grid Width="25" Height="25" Background="{Binding ElementName=TitleBar, Path=Background}">
                <TextBlock  Text="&#x10c3f;" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="White" />
            </Grid>
        </Button>
        <Button Command="SystemCommands.MinimizeWindowCommand" DockPanel.Dock="Right">
            <Grid Width="25" Height="25" Background="{Binding ElementName=TitleBar, Path=Background}">
                <TextBlock  Text="&#xE108;" HorizontalAlignment="Center" VerticalAlignment="Bottom" Foreground="White" />
            </Grid>
        </Button>
        <TextBlock Text="{Binding ElementName=root, Path=Title, FallbackValue='Application Title'}" Foreground="White" VerticalAlignment="Center"/>
    </DockPanel>
    <Grid>
        <TextBlock Text="Content goes here." VerticalAlignment="Center" HorizontalAlignment="Center"/>
    </Grid>
</DockPanel>
