在 Silverlight 中使用 ResourceDictionary 时出错 [英] Error using ResourceDictionary in Silverlight

问题描述

在我的 Silverlight 应用程序中，我有 UserControl，我想引用位于单独 XAML 文件中的 ResourceDictionary 中的 StaticResource.

In my Silverlight app I have UserControl and I want to reference a StaticResource in a ResourceDictionary that is in a separate XAML file.

我的用户控件如下所示:

My UserControl looks like this:

<UserControl x:Class="ResourceDictionaryHeadache.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480">
    <UserControl.Resources>
        <ResourceDictionary Source="/SampleData.xaml" />
    </UserControl.Resources>
    <Grid x:Name="LayoutRoot">
        <ListBox HorizontalAlignment="Stretch"
                 VerticalAlignment="Stretch"
                 ItemsSource="{StaticResource SampleData}">
        </ListBox>
    </Grid>
</UserControl>

我的 SampleData.xaml 文件如下所示:

My SampleData.xaml file looks like this:

<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
xmlns:Headache="clr-namespace:ResourceDictionaryHeadache">
<Headache:PersonList x:Key="SampleData">
    <Headache:Person Name="Joe" Age="20" />
    <Headache:Person Name="Sam" Age="25" />
    <Headache:Person Name="Dave" Age="30" />
</Headache:PersonList>

我将 SampleData.xaml 文件设置为 Content 的构建操作，当我运行应用程序时，我在 InitializeComponent() 行上收到 AG_E_PARSER_BAD_TYPE [Line: 5 Position: 44] 错误我的 UserControl 的构造函数.

I have the SampleData.xaml file set to a Build Action of Content and when I run the app I get an AG_E_PARSER_BAD_TYPE [Line: 5 Position: 44] error on the InitializeComponent() line of the constructor for my UserControl.

导致此错误的原因是什么，如何正确引用此资源?

What is causing this error and how can I correctly reference this resource?

推荐答案

资源字典中的这一行在我看来不正确:-

This line in your resource dictionary doesn't look right to me:-

 xmlns:Headache="clr-namespace:ResourceDictionaryHeadache"

您的 PersonList 类是否真的定义在名为 ResourceDictionaryHeadache 的命名空间中?

Is your PersonList class really defined in a Namespace called ResourceDictionaryHeadache?

不管是不是我怀疑代码失败的原因是因为 XAML 找不到 PersonList 类型.

Whether it is or isn't I suspect that the reason the code it failing is because XAML can't find the PersonList type.

编辑

天啊！我刚刚注意到，从 Source 中删除前面的/并将 SampleData.xaml 资源字典保留在其默认的页面"构建操作.

D'Oh! I just noticed, remove the preceding / from the Source and leave the SampleData.xaml Resource dictionary at its default Build Action of "Page".

换句话说，如果您只是使用添加新项目"然后资源字典"添加了 XAML 文件，您将只需要在您的页面 xaml 中使用它:-

In other words if you just added the XAML file using "Add New Item" then "Resource Dictionary" you would only need this in your page xaml:-

<UserControl.Resources> 
    <ResourceDictionary Source="SampleData.xaml" /> 
</UserControl.Resources>
