I'm trying to change default black background to #111. Here is the code that i tried to use

    <ResourceDictionary x:Key="Dark">

        ...

        <Color x:Key="SystemAltHighColor">#111</Color>

但它不起作用.我做错了什么?

But it doesn't work. What i'm doing wrong?

推荐答案

SystemAltHighColorBrush 不是 Windows 10 UWP 中使用的画笔.您可以在以下路径中仔细检查所有使用的资源:

SystemAltHighColorBrush is not a used brush in Windows 10 UWP. You can double check all used resources at the following path:

C:\Program Files (x86)\WindowsKits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.10240.0\Generic\generic.xaml

C:\Program Files (x86)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\10.0.10240.0\Generic\generic.xaml

如果您指的是应用程序的页面背景，那么您正在寻找 ApplicationPageBackgroundThemeBrush，因为这是每个新页面上使用的默认样式.

If you mean the application's page background, you're looking for ApplicationPageBackgroundThemeBrush as this is the default style used on each new page.

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

您正在尝试更改主题资源(它们在深色和浅色之间有所不同)，因此您的更改应反映这一点.使用适当的键覆盖主题词典.由于#111111 非常接近黑色，为了演示目的，我选择了花哨的绿色.

You're trying to change theme resources (they differ between dark and light), so your change should reflect this. Override the theme dictionaries with the appropriate keys. As #111111 is very close to black, I took a fancy green for demo purposes.

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>
            <ResourceDictionary x:Key="Default">
                <Color x:Key="SystemAltHighColor">#11CC11</Color>
                <SolidColorBrush x:Key="ApplicationPageBackgroundThemeBrush" Color="{ThemeResource SystemAltHighColor}" />
            </ResourceDictionary>
            <ResourceDictionary x:Key="Dark">
                <Color x:Key="SystemAltHighColor">#11CC11</Color>
                <SolidColorBrush x:Key="ApplicationPageBackgroundThemeBrush" Color="{ThemeResource SystemAltHighColor}" />
            </ResourceDictionary>
        </ResourceDictionary.ThemeDictionaries>
    </ResourceDictionary>
</Application.Resources>
