我似乎无法将合并词典添加到XAML中的合并词典集合中

Theme.xaml

应用程序资源

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Mine;component/Themes/Theme.xaml"/> 
            <!--
            <ResourceDictionary Source=="/Mine;component/Themes/Palette.Blue.xaml"/>
            <ResourceDictionary Source="/Mine;component/Themes/Template.xaml"/>
            -->
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>
注意：如果我将这两个ResourceDictionary都放在appation.Resources合并字典中（注释掉theme.xaml并取消注释其他两个字典），它们都会正确加载。但是，根据我们定义资源的方式，这可能意味着将加载相当多的资源，对于动态加载，我希望能够定义模板。

您的示例代码在App.xaml合并资源字典源中有一个双等号，用于palete.Blue.xaml。我假设这是你在这里发布的示例的一个输入错误，而不是你真正的问题

弄清楚如何在XAML中直接链接所有资源可能很棘手。最简单的方法是从Blend中的Resources面板。我创建了一个Silverlight应用程序，其中的资源文件名与您的示例类似，然后在Blend中打开该项目，并很快将它们链接在一起

当然，如果您链接来自不同程序集的资源，它看起来会有所不同。实际上，在这种情况下，我建议在代码隐藏中合并词典。

这是一个优化错误，请参阅链接

论建筑中每一个对象的创造 XAML，如果存在默认样式 （即带有类型键的样式） 风格应该被应用。尽你所能 想象一下有几个表演 优化以实现这一点（暗示） 查找一个尽可能轻的重量。一个 其中之一就是我们不看里面 资源字典，除非 标记为“包含默认值” 风格”。有一个错误：如果你的 默认样式嵌套在合并样式中 三级词典（或 （更深层的）顶级词典没有 标记，以便搜索跳过它。 解决方法是设置默认值 从根本上说，任何东西的风格 字典

因此，将虚拟样式添加到根字典可以解决此问题。范例

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Mine;component/Themes/Theme.xaml"/>
        </ResourceDictionary.MergedDictionaries>
        <!-- Dummy Style, anything you won't use goes -->
        <Style TargetType="{x:Type Rectangle}" />
    </ResourceDictionary>
</Application.Resources>
如果这发生在您自己的控件上，我发现另一种解决方案是将
DefaultStyleKey
属性设置为null：

DefaultStyleKeyProperty.OverrideMetadata(typeof(MyControl), new FrameworkPropertyMetadata(null));
我不知道这为什么有效，但似乎有效

这是theme.xaml的完整代码吗？因为我认为您只需要使用ResourceDictionary标记来开始和结束它，就可以让它工作了。不，它实际上已经在一个合并的字典中了。这显然是一个转录错误（不在实际文件中）。我知道如何单独添加每个资源（通过代码隐藏或创建新的合并词典）但问题似乎与向ResourceDictionary添加一个mergedDictionary有关，它可以作为单独合并字典的源或部分。请检查字典xaml文件的生成操作。您可能需要将其从默认页面更改为资源。我在.NET 4中遇到了这个问题，这就解决了它。出于某种原因，这对我不起作用。启动时，它会抛出一个异常（DependencyProperty.UnsetValue对“前台”无效），这表明未添加资源字典。我的设置与上面在.NET 4.5上的代码相同。这在VS2010中不起作用。NET 4.0不编译。错误<代码>错误7属性元素不能位于元素内容的中间。它们必须在内容之前或之后。有人知道此错误是否已在.NET 4.5或更高版本中修复吗？Microsoft Connect已停用，因此我无法从提供的链接判断。
