您需要编辑预定义的按钮样式以合并您想要的样式。使用混合，您可以更新按钮syle

<Style x:Key="ButtonStyle1" TargetType="Button">
            <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundBaseLowBrush}"/>
            <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
            <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundTransparentBrush}"/>
            <Setter Property="BorderThickness" Value="{ThemeResource ButtonBorderThemeThickness}"/>
            <Setter Property="Padding" Value="8,4,8,4"/>
            <Setter Property="HorizontalAlignment" Value="Left"/>
            <Setter Property="VerticalAlignment" Value="Center"/>
            <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
            <Setter Property="FontWeight" Value="Normal"/>
            <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
            <Setter Property="UseSystemFocusVisuals" Value="True"/>
            <Setter Property="Template">
