ResourceDictionary.MergedDictionaries属性有一个奇怪的问题 [英] An odd problem with ResourceDictionary.MergedDictionaries property

问题描述

我在主题文件夹中制作了两个xaml资源文件

generic.xaml

I made two xaml resource files in themes folder

generic.xaml

<ResourceDictionary

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="themes/msofficeui.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

msofficeui.xaml

msofficeui.xaml

<ResourceDictionary

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

  xmlns:local="clr-namespace:System.Windows.Resources.Libraries">

    <Color A="#FF" R="#BF" G="#BF" B="#BF" x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:ColorLibrary}, ResourceId=MSOLightGray}"/>
    <Color A="#FF" R="#91" G="#91" B="#91" x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:ColorLibrary}, ResourceId=MSOGray}" />
    <Color A="#FF" R="#F9" G="#E1" B="#89" x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:ColorLibrary}, ResourceId=MSOLightGold}" />
    <Color A="#FF" R="#FF" G="#D8" B="#6C" x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:ColorLibrary}, ResourceId=MSOGold}" />
    <Color A="#FF" R="#38" G="#38" B="#38" x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:ColorLibrary}, ResourceId=MSOBlack}" />

    <LinearGradientBrush x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:BrushLibrary}, ResourceId=MSORibbonBackgroundGray}"

                         StartPoint="0.5,0" EndPoint="0.5,1">
        <GradientStop Color="#FFBFBFBF" Offset="0" />
        <GradientStop Color="#FF919191" Offset="1" />
    </LinearGradientBrush>

    <RadialGradientBrush x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:BrushLibrary}, ResourceId=MSOButtonBackgroundEnter}" 

                         GradientOrigin = "0.5,1.02" Center="0.5,1.02" RadiusX="0.8" RadiusY="0.2">
        <GradientStop Color="#FFFFFFFF" Offset="0" />
        <GradientStop Color="#FFF9E189" Offset= "1" />
    </RadialGradientBrush>

    <RadialGradientBrush x:Key="{ComponentResourceKey TypeInTargetAssembly={x:Type local:BrushLibrary}, ResourceId=MSOButtonBackgroundPressed}" Center="0.5,1.5">
        <GradientStop Color="#FFFFFFFF" Offset="0" />
        <GradientStop Color="#FFFFD86C" Offset= "0.55" />
    </RadialGradientBrush>

</ResourceDictionary>

当我尝试使用应用程序中的一种资源时，收到如下消息:

无法找到资源"themes/msofficeui.xaml".
在MS.Internal.AppModel.ResourcePart.GetStreamCore(FileMode模式，FileAccess访问)处
在System.IO.Packaging.PackagePart.GetStream(FileMode模式，FileAccess访问)处
在System.IO.Packaging.PackWebResponse.CachedResponse.GetResponseStream()
在System.IO.Packaging.PackWebResponse.GetResponseStream()
在System.IO.Packaging.PackWebResponse.get_ContentType()
在MS.Internal.WpfWebRequestHelper.GetContentType(WebResponse响应)
在MS.Internal.WpfWebRequestHelper.GetResponseStream(WebRequest请求，ContentType& TypeType)
在System.Windows.ResourceDictionary.set_Source(Uri值)
在System.Windows.Baml2006.WpfSharedBamlSchemaContext中.< Create_BamlProperty_ResourceDictionary_Source> b__1c4(对象目标，对象值)
在System.Windows.Baml2006.WpfKnownMemberInvoker.SetValue(对象实例，对象值)
在MS.Internal.Xaml.Runtime.ClrObjectRuntime.SetValue(XamlMember成员，Object obj，Object值)
在MS.Internal.Xaml.Runtime.ClrObjectRuntime.SetValue(Object inst，XamlMember属性，Object value)

我将在general.xaml中提到的msofficeui.xaml的uri更改为绝对包Uris和相对包Uris，但仍然抛出相同的异常.

我直接将msofficeui.xaml的内容直接放入通用文件中，而不使用MergedDictionaries，然后一切正常.所以这绝对是一个Uri问题.

uri有什么问题?我花了几个小时.我尽了我所能想象的一切.现在我很生气.....

when i tried to use one of the resources in my app, I got a message as follows:

Cannot locate resource ''themes/msofficeui.xaml''.

at MS.Internal.Xaml.Runtime.ClrObjectRuntime.SetValue(XamlMember member, Object obj, Object value)
at MS.Internal.Xaml.Runtime.ClrObjectRuntime.SetValue(Object inst, XamlMember property, Object value)

I changed the uri referred to msofficeui.xaml in generic.xaml to both absolute and relative pack Uris, but the same exception continued to be thrown out.

I put the stuff of msofficeui.xaml directly in generic without using MergedDictionaries, then everything goes fine. So it is definitely a Uri problem.

What''s wrong with the uri? It has taken me a couple of hours. I tried every way I can imagine. Now I''m mad.....

推荐答案

由于它们都在Themes目录中，因此您实际上是在告诉ResourceDictionary合并可以修复文件夹"themes/themes/msofficeui.xaml"中的ResourceDictionary

Since they are both in the Themes directory you are actually telling the ResourceDictionary to merge the ResourceDictionary of the folder "themes/themes/msofficeui.xaml" to fix it you can

1. 从"themes/msofficeui.xaml"更改为仅"msofficeui.xaml"
2. 从"themes/msofficeui.xaml"更改为"/AssemblyName;component/themes/msofficeui.xaml"

在第二种方法中，您被迫要求从Assembly资源中查找正确的信息，当在不同文件夹中使用多个ResourceDictionaries时，这特别有用.

In the seccond approach you are forcing to ask from the Assembly resources to find the correct info, this is specialy useful when working with multiple ResourceDictionaries in different folders.

代码:

<ResourceDictionary

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/AssemblyName;component/themes/msofficeui.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

希望这会有所帮助

万事如意
