UWP在不同类库使用ResourceDictionaries

Posted 2020-06-09

　　通常我们在类库中定义资源的时候可以在Theme/Generic.xaml中定义，当类库加载的时候，会自动加载Generic.xaml文件中的资源，通常用在控件库中，但如果控件多了之后，所有的Style都定义在Generic.xaml中会是的文件很大很臃肿，这时候我们可以通过Uri的方式引用外部的资源，把资源定义在多个文件中，可以更方便于管理，在程序集中定义引用外部ResourceDictionary比较特殊，方法如下

WinRT:　　

　　ms-appx:///{ASSEMBLY_NAME}/{RESOURCE_FILE_PATH}
　　　　如：ms-appx:///Contoso.Core/Resources/CoreStyles.xaml

 

Sliverlight

　　/{ASSEMBLY_NAME};component/{RESOURCE_FILE_PATH}
　　　　如：/Contoso.Core;component/Resources/CoreStyles.xaml

 

 

下面为完整Demo

1、WinRT

<Application
 x:Class="Contoso.UI.App"
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <!--Application Resources-->
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="ms-appx:///Contoso.Core/Resources/CoreStyles.xaml" />
                <ResourceDictionary Source="ms-appx:///Contoso.UI.Core/Resources/UICoreStyles.xaml" />
            </ResourceDictionary.MergedDictionaries>

            <!-- Other style definitions can still go here -->
            <Style TargetType="Button">
            </Style>

        </ResourceDictionary>
    </Application.Resources>
</Application>

2、Silverlight

<Application
 x:Class="Contoso.UI.App"
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
 xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone">

    <!--Application Resources-->
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/Contoso.Core;component/Resources/CoreStyles.xaml"/>
                <ResourceDictionary Source="/Contoso.UI.Core;component/Resources/UICoreStyles.xaml"/>
            </ResourceDictionary.MergedDictionaries>

            <!-- Other style definitions can still go here -->
            <Style TargetType="Button">
            </Style>

        </ResourceDictionary>
    </Application.Resources>

    <Application.ApplicationLifetimeObjects>
        <!--Required object that handles lifetime events for the application-->
        <shell:PhoneApplicationService
 Launching="Application_Launching" Closing="Application_Closing"
 Activated="Application_Activated" Deactivated="Application_Deactivated"/>
    </Application.ApplicationLifetimeObjects>

</Application>
