c# - 更改Windows Phone 通用应用程序中内容对话框按钮的样式

Question

我在我的 xaml 中定义了这个内容对话框:

    <ContentDialog x:Name="AlertMessage" Background="#363636" IsSecondaryButtonEnabled="True" SecondaryButtonText="Cancel"  IsPrimaryButtonEnabled="True" PrimaryButtonText="Ok" >
        <ContentDialog.Content>
            <StackPanel Name="rootStackPanel" Height="Auto"  >
                <StackPanel Margin="0">
                    <StackPanel Margin="0,0,0,10" Orientation="Horizontal">
                        <TextBlock x:Name="HeadingText" x:FieldModifier="public" Style="{StaticResource ApplicationMessageBoxHeadingStyle}" Text="Alert"  />
                        <Image Margin="10,05,0,0" Source="/Assets/Images/alert.png" Width="35"></Image>
                    </StackPanel>
                    <TextBlock x:FieldModifier="public" x:Name="ContentText" Style="{StaticResource ApplicationMessageBoxErrorStyle}" Text="Are you sure you want to log off ?" />
                </StackPanel>
            </StackPanel>
        </ContentDialog.Content>
    </ContentDialog>

我这样调用它:

private void AppBarButton_Click(object sender, RoutedEventArgs e)
    {
        MessageBox();
    }
    private async void MessageBox()
    {
        ContentDialogResult LogoutDialog = await AlertMessage.ShowAsync();

        if (LogoutDialog == ContentDialogResult.Primary)
        {
            this.Frame.Navigate(typeof(MainPage));
        }
        else
        {
            // User pressed Cancel or the back arrow.
            // Terms of use were not accepted.
        }

    }

问题: 是我的应用程序中的所有按钮都有一个样式。我也想对该对话框的主要和次要按钮应用相同的样式。而且我无法弄清楚如何实现这一目标。是否可以将样式应用于这些按钮？

我使用此代码更改我的 UWP 应用上的按钮颜色。

 var cd = new ContentDialog();
 cd.Content = "Remove file ?";
 cd.Title = "Remove file";
 cd.PrimaryButtonText = "OK";
 cd.SecondaryButtonText = "Cancel";
 var bst = new Windows.UI.Xaml.Style(typeof(Button));
 bst.Setters.Add(new Setter(Button.BackgroundProperty, Colors.Red));
 bst.Setters.Add(new Setter(Button.ForegroundProperty, Colors.White));
 cd.PrimaryButtonStyle = bst;
 var ress = await cd.ShowAsync();
