在WPF应用程序中,我在单独的资源字典中定义了默认控件样式(例如"ButtonStyle.xaml"),并将它们作为合并字典添加到名为"ResDictionary.xaml"的资源字典中.
如果我在我的App.xaml中将此"ResDictionary.xaml"称为合并字典,则不会应用默认样式.但是,如果我引用"ButtonStyle.xaml",它可以正常工作.
如果我在.NET 3.5或3.0中重新编译相同的代码,它会识别并应用"App.xaml"到"ResDictionary.xaml"中引用的默认样式,但不能在.NET 4.0中应用.
在运行时,如果我检查Application.Current.Resources字典,那么默认样式就在那里,但只有在Button控件中显式指定Style属性时才会应用它们.
是否有任何解决方案在.NET 4.0中以这种方式引用资源字典(包含默认样式)?
App.xaml中:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/ResDictionary.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
