C# 如何更改UWP TimePikcerFlyout中的字体大小？

我想把时间选择器的字体调大一点，有可能吗

您所指的区域是的

循环选择器。默认字体大小为15，如下所示

<Style TargetType="LoopingSelector">
    <Setter Property="ShouldLoop" Value="True" />
    <Setter Property="UseSystemFocusVisuals" Value="{StaticResource UseSystemFocusVisuals}" />
    <Setter Property="ItemTemplate">
        <Setter.Value>
            <DataTemplate>
                <StackPanel VerticalAlignment="Center">
                    <TextBlock Text="{Binding PrimaryText}" FontFamily="{ThemeResource ContentControlThemeFontFamily}" FontSize="15" />
                </StackPanel>
            </DataTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Control">
                <Grid>

                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="CommonStates">
                            <VisualState x:Name="Normal" />

                            <VisualState x:Name="PointerOver">

                                <Storyboard>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="UpButton" Storyboard.TargetProperty="Visibility">
                                        <DiscreteObjectKeyFrame KeyTime="0" Value="Visible" />
                                    </ObjectAnimationUsingKeyFrames>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="DownButton" Storyboard.TargetProperty="Visibility">
                                        <DiscreteObjectKeyFrame KeyTime="0" Value="Visible" />

                                </Storyboard>
                            </VisualState>
                        </VisualStateGroup>

                    </VisualStateManager.VisualStateGroups>
                    <ScrollViewer x:Name="ScrollViewer"

                HorizontalAlignment="Stretch"

                Visibility="Collapsed"
                Style="{StaticResource DateTimePickerFlyoutButtonStyle}"
                Background="{ThemeResource LoopingSelectorButtonBackground}"

                    <RepeatButton x:Name="DownButton"

                Padding="0"
                HorizontalAlignment="Stretch"
                VerticalAlignment="Bottom"
                Visibility="Collapsed"
                Style="{StaticResource DateTimePickerFlyoutButtonStyle}"
                Background="{ThemeResource LoopingSelectorButtonBackground}"
                IsTabStop="False" />

                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>



如果你想让它更大。您只需将以下字体大小修改为另一个值。然后将完整样式放置在App.xaml文件的
中

谢谢，这是正确的！例如，我不能在应用程序资源中使用它，也不能在页面资源中使用它？我尝试在页面资源中使用它，但它不起作用，因为它位于弹出控件中。
