是否有方法同时为所有文本控件设置默认字体系列？其思想不是分别为每个控件指定字体系列。

您可以在styles.xaml中设置一个变量，并将所有FontFamilys设置为该变量
例如：

<System:String x:Key="StrFontFamily">Times New Roman</System:String>

...

    <Style TargetType="Label">
        <Setter Property="TextColor" Value="{AppThemeBinding Light={StaticResource Gray900}, Dark={StaticResource White}}" />
        <Setter Property="FontFamily" Value="{StaticResource StrFontFamily}"/>
        <Setter Property="FontSize" Value="14" />
        <Setter Property="VisualStateManager.VisualStateGroups">
            <VisualStateGroupList>
                <VisualStateGroup x:Name="CommonStates">
                    <VisualState x:Name="Normal" />
                    <VisualState x:Name="Disabled">
                        <VisualState.Setters>
                            <Setter Property="TextColor" Value="{AppThemeBinding Light={StaticResource Gray300}, Dark={StaticResource Gray600}}" />
                        </VisualState.Setters>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateGroupList>
        </Setter>
    </Style>

公平地说，您仍然可以分别为每个控件设置它，但同时使用一个变量。
如果这看起来像是对你有用的东西，那么下面的代码就是整个Styles.xaml，其中定义了变量。将它从这里复制到 {Project}/Resources/Styles/Styles.xaml 中进行测试。

<?xml version="1.0" encoding="UTF-8" ?>
<?xaml-comp compile="true" ?>
