Xaml 如何更改windows通用应用程序的默认强调色？

我想将我的应用程序（windows universal app）中的强调色从默认颜色更改为在我的应用程序中定义的自定义颜色

你知道我该怎么做吗？

你试过使用：

(App.Current.Resources["PhoneAccentBrush"] as SolidColorBrush).Color = Colors.Blue;

在你的App.xaml.cs？

中，我在Microsoft论坛上找到了这个，并帮助我解决了这个问题：

您无法真正更改应用程序中的基本强调色，因为它是由系统主题颜色（任务栏、开始菜单等）定义的。但是，可以使用样式修改强调色。下面是一个例子：

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:App1">

    <!-- Basic Colors -->
    <SolidColorBrush x:Key="SystemAccentTransparentHighBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.9"/>
    <SolidColorBrush x:Key="SystemAccentTransparentMediumHighBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.7" />
    <SolidColorBrush x:Key="SystemAccentTransparentMediumBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.6" />
    <SolidColorBrush x:Key="SystemAccentTransparentMediumLowBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.5" />
    <SolidColorBrush x:Key="SystemAccentTransparentLowBrush" Color="{ThemeResource SystemAccentColor}" Opacity="0.3" />
    <SolidColorBrush x:Key="SystemAccentHighlightBrush" Color="{ThemeResource SystemAccentColor}" />
    <SolidColorBrush x:Key="SystemBlackBrush" Color="{ThemeResource SystemChromeBlackHighColor}" />
    <SolidColorBrush x:Key="SystemWhiteBrush" Color="{ThemeResource SystemChromeWhiteColor}" />
    <SolidColorBrush x:Key="SystemGreyHighBrush" Color="#FFE0E0E0" />
    <SolidColorBrush x:Key="SystemGreyMediumHighBrush" Color="#FFA0A0A0" />
    <SolidColorBrush x:Key="SystemGreyMediumBrush" Color="#FF808080" />
    <SolidColorBrush x:Key="SystemGreyMediumLowBrush" Color="#FF606060" />
    <SolidColorBrush x:Key="SystemGreyLowBrush" Color="#FF404040" />
    <SolidColorBrush x:Key="SystemAppBackgroundBrush" Color="{ThemeResource ApplicationPageBackgroundThemeBrush}" />

    <Style x:Key="GridStyle_Page" TargetType="Grid">
        <Setter Property="HorizontalAlignment" Value="Left" />
        <Setter Property="VerticalAlignment" Value="Top" />
        <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto" />
        <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" />
        <Setter Property="Background" Value="{StaticResource SystemBlackBrush}" />
    </Style>

</ResourceDictionary>

我希望这有帮助，并为迟来的答复感到抱歉。我只是在谷歌搜索其他东西时遇到了你的问题
