WPF如何在C#代码中引用资源字典中的样式？

首先在页面里合并资源字典，放在<Window.Resources>或<Page.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="资源字典名.xaml"/>

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

然后在后台指定即可。

控件名.Style = Resources["样式的Key"] as Style

只要在App.xaml里面添加字典的时候按先后顺序就可以了

<Application.Resources>

        <ResourceDictionary>

            <ResourceDictionary.MergedDictionaries>

                <ResourceDictionary Source="Skin/BrushResources.xaml"/>

                <ResourceDictionary Source="Skin/ImageResources.xaml"/>

                <ResourceDictionary Source="Skin/AppResources.xaml"/>

            </ResourceDictionary.MergedDictionaries>

        </ResourceDictionary>

    </Application.Resources>

如上述代码所示，AppResources.xaml里面用到BrushResources.xaml里面的资源
