为什么使用ComponentResourceKey“无法解析资源”？

Question

我尝试使用ComponentResourceKey重用自定义资源，但它不起作用，并且我收到以下警告：

Warning 12 The resource "{ComponentResourceKey ResourceId=SadTileBrush, TypeInTargetAssembly={x:Type res:CustomResources}}" could not be resolved.

这是ResourceLibrary/Themes/generic.xaml

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:ResourceLibrary">
    <ImageBrush x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:CustomResources},
                        ResourceId=MyBrush}"
        ImageSource="ResourceLibrary;component/../../myImage.jpg">
    </ImageBrush>
</ResourceDictionary>

和ResourceLibrary/CustomResources.cs

namespace ResourceLibrary{
    public class CustomResources{}
}

用法如下(SomeOtherProject/MyWindow.xaml格式)：

<Button Background="{DynamicResource {ComponentResourceKey
                    TypeInTargetAssembly={x:Type res:CustomResources}, 
                    ResourceId=MyBrush}}"> Some text </Button>

为什么“资源无法解析”？

请注意，我注意到了SO问题"Getting a ComponentResourceKey to Work?"，但这种情况下的问题是在代码隐藏中，无论如何我都没有代码隐藏……

使用ComponentResourceKey时，请确保xmlns前缀与.dll类文件不同

(DLL= 'Local‘- this class = 'res')

<Button Background="{DynamicResource {ComponentResourceKey TypeInTargetAssembly={x:Type res:CustomResources}, ResourceId=SadTileBrush}}" Padding="5" Margin="5" FontWeight="Bold" 
            FontSize="14" Content="A Resource From ReusableResourceLibrary" />

我创建了这个字典类来嵌入/合并我的.dll字典

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="pack://application:,,,/ReusableResourceLibrary;component/Dictionary1.xaml" />
</ResourceDictionary.MergedDictionaries>
<ImageBrush x:Key="DicTileBrush" TileMode="Tile" ViewportUnits="Absolute" Viewport="0 0 50 50" ImageSource="../Resources/Images/Smiley_Happy.png" Opacity="0.3" />
</ResourceDictionary>

然后在我实际的窗口/用户控件中，我将窗口/用户控件资源与上面的资源字典合并在一起，并且它起作用了

希望这能有所帮助
