Wpf 类库中资源字典中的图标不会显示在主应用程序窗口中

编辑： 我创建了一个更简单的概念证明：

我有一个具有以下MainWindow.xaml的WPF应用程序：

<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
    <Image Source="pack://application:,,,/IconContainer;component/Icons/Blocked.png"/>
</Grid>

 <GridViewColumn.CellTemplate>
    <DataTemplate>
       <Image Source="{Binding IconName, 
              Converter={StaticResource IconConverter},ConverterParameter=S}"
       />
    </DataTemplate>
 </GridViewColumn.CellTemplate>

当我在转换器中设置断点时，我可以看到构造了正确的URI，并且icon变量不是null

否则，用户界面中不会显示任何内容，VisualStudio的即时窗口中也不会显示绑定或其他错误

哪里出错了？

u r缺少属性

x:Shared=False

 <BitmapImage x:Key="ErrorL" x:Shared="False" UriSource="errorL.png"/> 

希望它能解决您的问题。

估计同事们（g.u.y.s.没有通过SO的亵渎过滤器：-）），请注意这一点，否则您将像我一样失去数小时毫无意义的调试： 将图标的生成操作设置为资源

在类库或主应用程序中有图标？在类库中，这就是要点：-）rt。。可以尝试将UriSource更新为uri值吗pack://application:，，，/ReferencedAssembly；component/icon.pngI已经尝试过了，不起作用。。。我已经创建了一个概念证明。很快就会贴出来。更容易理解。如果你真的不会说“伙计”的话就测试。WFM（padpad）
