在图书馆项目中链接 ThemeDictionaries [英] Linking ThemeDictionaries in Library Project

问题描述

我在名为 Light.xaml 和 Dark.xaml 的 Themes 文件夹中创建了 2 个 ResourceDictionary/theme 文件.

I created 2 ResourceDictionary/theme files in Themes folder named Light.xaml and Dark.xaml.

在两个文件中添加了名称为 BgColor 的 SolidColorBrush :

Added SolidColorBrush with name BgColor in both files :

//在 Light.xaml 中

//在 Dark.xaml 中

在 Application 类型的项目中，我可以在 App.xaml 中添加以下 XAML 代码，以便我可以在我的 UserControl 中引用此资源:

In Application type project, I can add below XAML code in App.xaml so I can reference this resource in my UserControl :

<Application>
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.ThemeDictionaries>
                <ResourceDictionary x:Key="Dark" Source="Themes/Dark.xaml" />
                <ResourceDictionary x:Key="Light" Source="Themes/Light.xaml"/>
            </ResourceDictionary.ThemeDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

由于这是 Library Project，我的项目中没有 App.xaml.

Since this is Library Project, there's no App.xaml on my project.

那么如何链接这个ThemeDictionaries 以便我可以在Library Project 的UserControl 中使用它?

So how to link this ThemeDictionaries so I can use it in my UserControl in Library Project ?

您可以在 App.xaml 中引用资源字典，如下所示:

You can reference the resource dictionary in your App.xaml like below:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>
            <ResourceDictionary x:Key="Dark" Source="ms-appx:///MyThemeLibrary/Themes/Dark.xaml"/>
            <ResourceDictionary x:Key="Light" Source="ms-appx:///MyThemeLibrary/Themes/Light.xaml"/>
        </ResourceDictionary.ThemeDictionaries>
    </ResourceDictionary>
</Application.Resources>

MyThemeLibrary 是类库的引用名称.之后，您可以使用您在 Dark.xaml 和 Light.xaml 中定义的主题，如下所示:

MyThemeLibrary is the reference name of your class library. After that you can use the theme that you defined in Dark.xaml and Light.xaml like below:

<UserControl
    ...
    d:DesignHeight="300"
    d:DesignWidth="400">

    <Grid Background="{ThemeResource BgColor}">
    </Grid>
</UserControl>
