关于wpf：Metro MahApps MessageBox主题


Metro MahApps MessageBox theme

也许有人可以告诉我如何正确地在Metro窗口中实现Async消息，使其具有应用程序的当前主题和口音？

演示示例中的代码有效，但主题和重点仍然是默认设置：

private async void ClosingApp(object sender, System.ComponentModel.CancelEventArgs e)
    {
        e.Cancel = !_shutdown;
        if (_shutdown) return;
        var mySettings = new MetroDialogSettings()
        {
            AffirmativeButtonText ="Quit",
            NegativeButtonText ="Cancel",
            AnimateShow = true,
            AnimateHide = false
        };
        var result = await this.ShowMessageAsync("Quit application?",
           "Sure you want to quit application?",
            MessageDialogStyle.AffirmativeAndNegative, mySettings);

        _shutdown = result == MessageDialogResult.Affirmative;
        if (_shutdown)
            Application.Current.Shutdown();
    }

当我简单地更改主题时：

1

 private void MenuItem_Click(object sender, RoutedEventArgs e)
    {
        // set the Red accent and dark theme only to the current window
        var theme = ThemeManager.GetAppTheme("BaseDark");
        var accent = ThemeManager.GetAccent("Red");
        ThemeManager.ChangeAppStyle(Application.Current, accent, theme);
    }

我得到默认的白色和蓝色MessageBox。 我究竟做错了什么？

我只需要添加默认的资源字典



在App.xaml中

我已经尝试过您的代码，并且可以正常工作。 我仅将ButtonItem_Click中的MenuItem_Click转换了，但这无关紧要。

如果单击设置按钮后关闭了应用程序，我将得到黑色背景和红色"退出"，如下所示。

而不是最初的

我有标准的Window1.xaml开头

        Closing="App_Closing"
    Title="Test" Height="600" Width="600"
