C# wpf-上下文菜单-在动态资源中重用静态资源

我有一个用户控件，其资源如下：

<UserControl.Resources>

    <Image x:Key="IconPrinter" Source="/PrintViewerWPF;component/Resources/Images/printer.png" />

    <MenuItem x:Key="PrintDoc" 
              Header="Print" 
              Click="PrintDoc_OnClick"
              Icon="{StaticResource IconPrinter}" />

    <ContextMenu x:Key="MergedContextMenu">
        <StaticResource ResourceKey="PrintDoc"/>
    </ContextMenu>

    <ContextMenu x:Key="SingleContextMenu">
        <StaticResource ResourceKey="PrintDoc"/>
    </ContextMenu>

    <DataTemplate x:Key="mergedDocDisplayGrid">
        <StackPanel StackPanel.ContextMenu="{DynamicResource MergedContextMenu}" />
    </DataTemplate>

    <DataTemplate x:Key="singleDocDisplayGrid">
        <StackPanel StackPanel.ContextMenu="{DynamicResource SingleContextMenu}" />
    </DataTemplate>

</UserControl.Resources>

内部异常是不言自明的，我确信我能够在代码背后解决这个问题，但是我觉得必须在XAML中正确地完成这项工作，因为菜单项的重用对我来说很重要

任何帮助都将不胜感激！谢谢

尝试

StaticResourceExtension

和

x:Shared=“false”

检查。

尝试

Message - Add value to collection of type 'System.Windows.Controls.ItemCollection' threw an exception.

Inner - Element already has a logical parent. It must be detached from the old parent before it is attached to a new one.
