wpf - App.xaml 中的合并字典

Question

我在一个单独的.xaml. 我window使用以下指令将它们加载到我的内部：

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/ScreenToGif;component/Themes/IconSet.xaml"></ResourceDictionary>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

我有很多窗口，所以我想简单地将这段代码放在App.xaml.

我正在尝试这个：

<Application.Resources> <!-- Error, The property "Resources" can only be set once. -->
    <ResourceDictionary x:Key="IconSet"> <!--Not sure why this?-->
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Mine;component/Themes/Theme.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>

<!--Here goes the rest of the file, with Style and DropShadowEffect... -->
</Application.Resources>

所以这里是问题：

所有示例都没有使用x:Key属性，但它给了我一个错误，说我需要。当我这样做时，它说我不能拥有多个属性Resource......

请看评论文字

<Application.Resources>    
    <ResourceDictionary>           
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Mine;component/Themes/Theme.xaml"/>
        </ResourceDictionary.MergedDictionaries>

        <!--You have to add other style here only-->

    </ResourceDictionary>

<!--Not Here-->

</Application.Resources>
