Question

我有一个混合WinForms / WPF桌面应用程序运行在Windows 10上，但仍以.NET 3.5为目标。它具有白天模式，黄昏模式和夜间模式。在夜间模式下，基本上所有东西都变成黑色的红色，但标题栏仍默认为白色。

在“设置”>“个性化设置”>“颜色”>“在以下表面上显示强调色”，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以编程方式更改从应用程序创建的所有Windows的标题栏背景和前景色？我可以根据需要使用p / Invoke。

如果没有，我也将接受一种以编程方式全局更改标题栏颜色的方法（系统上的所有Windows），甚至可以提供一种自动检查该框（标题栏上的重点颜色）并设置为深色的方法强调颜色。

编辑：可以不必设置WindowStyle =“ None”并自定义实现标题栏吗？那就是我已经（疲倦）在做的事情。

在WPF（我假设使用WinForms）中，创建无边界窗口和自己创建标题栏更加容易。这是执行此操作的WPF代码，

首先使用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();
        }
    }

}

现在的XAML：

        </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>
