每一个辞条必须有一个相关的关键属性 [英] Each Dictionary entry must have an associated key attribute

问题描述

我使用C＃和GalaSoft的MVVM光强工具包编程W¯¯的Windows 8.1应用程序

I am programming w Windows 8.1 App using C# and the MVVM-Light Toolkit from GalaSoft.

我只有下面的代码：

<Application.Resources>
    <vm:ViewModelLocator x:Key="Locator" xmlns:vm="using:Scedule.ViewModel" />

    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Resource Dictionaries/StandardStyles.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>      
</Application.Resources>

错误每个字典条目必须具有相关联的密钥属性的发生，只有消失时，我要么删除

The error "Each Dictionary entry must have an associated key attribute" occurs and only disappears when I either remove

    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Resource Dictionaries/StandardStyles.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary> 

或

    <vm:ViewModelLocator x:Key="Locator" xmlns:vm="using:Scedule.ViewModel" />

谁能告诉我这里的问题是什么？

Can anyone tell me what the problem here is?

推荐答案

注意 Application.Resources 要求<$ C的一个实例$ C> ResourceDictionary中，所以你必须做这样的事情：

Note that Application.Resources requires an instance of ResourceDictionary, so you have to do something like this:

<Application.Resources>    
  <ResourceDictionary>
    <vm:ViewModelLocator x:Key="Locator" xmlns:vm="using:Scedule.ViewModel" />
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="Resource Dictionaries/StandardStyles.xaml"/>
    </ResourceDictionary.MergedDictionaries>
  </ResourceDictionary>      
</Application.Resources>

所以这并不奇怪的话，那也是不是一个错误。如果你希望你的 ResourceDictionary中被视为一种资源，你当然必须提供一些键它，但是在这种情况下，你真的想 ResourceDictionary中的一个实例分配给 Application.Resources

So it's not strange at all, it's also not a bug. If you want your ResourceDictionary to be treated as a resource, you of course have to provide some Key for it, however in this case you really want to assign an instance of ResourceDictionary to the Application.Resources
