我尝试了以下方法：

{
    ContentDialog dialog = new ContentDialog()
    {
        Title = title,
        Content = text,
        CloseButtonText = closeButtonText
    };
    
    dialog.Background = new AcrylicBrush()
    {
        BackgroundSource = 0,
        TintOpacity = 0.5,
        Opacity = 0.5,  
    };
    
    await dialog.ShowAsync();
}

如果您可以在内容对话框后看到按钮，则您的代码很好。

我不使用亚克力画笔的代码。

    private async void Button_OnClick(object sender, RoutedEventArgs e)
    {
        var title = "title";
        var text = "text";
        var closeButtonText = "close";

        ContentDialog dialog = new ContentDialog()
        {
            Title = title,
            Content = text,
            CloseButtonText = closeButtonText
        };           

        dialog.Background = new SolidColorBrush(Color.FromArgb(255, 202, 24, 37));

        await dialog.ShowAsync();
    }

        var title = "title";

            Content = text,
            CloseButtonText = closeButtonText
        };

        if (Windows.Foundation.Metadata.ApiInformation.IsTypePresent(
            "Windows.UI.Xaml.Media.XamlCompositionBrushBase"))
        {
            // check that this API is available on the user’s machine
            dialog.Background = new AcrylicBrush()
            {
                BackgroundSource = Windows.UI.Xaml.Media.AcrylicBackgroundSource.HostBackdrop,
                TintOpacity = 0.5,
                FallbackColor = Color.FromArgb(255, 202, 24, 37),
                Opacity = 0.5,
            };
        }

        await dialog.ShowAsync();
    }
