如何在XAML中的容器(如dll)中获取特定图标？

                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
   <Canvas x:Key="IconName" Width="24" Height="24" Clip="F1 M 0,0L 24,0L 24,24L 0,24L 0,0">
        <!-- 在这里添加图标的绘制代码 -->
    </Canvas>
</ResourceDictionary>

        xmlns:local="clr-namespace:YourNamespace">
   <Window.Resources>
       <ResourceDictionary>
           <ResourceDictionary.MergedDictionaries>
               <local:Icons />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
       <ContentControl Content="{StaticResource IconName}" />
    </Grid>
</Window>
