重写类库中的系统控制样式
本文关键字：系统控制 样式 类库 重写 | 更新日期: 2023-09-27 17:49:18
你可以看到，在默认的Aero主题中，ListBoxItem的样式真的很过时，所以我找到了一个新的样式，如果我把它放在MainWindow.Resources中，它就会起作用。
但是如果我把它放在Themes/Aero.NormalColor.xaml在一个类库和引用它(我也使用了一些自定义控件在该库)，但它不起作用。有解决方法吗?(
ThemeInfo for class library:
[assembly: ThemeInfo(ResourceDictionaryLocation.SourceAssembly, ResourceDictionaryLocation.SourceAssembly)]
主项目ThemeInfo:
[assembly: ThemeInfo(ResourceDictionaryLocation.None, ResourceDictionaryLocation.SourceAssembly)]
Themes/Aero.NormalColor.xaml:

</ResourceDictionary>
如果你想把这个'override'应用到应用程序中的所有ListBoxItem，去掉'x:Key="{x:Type ListBoxItem}"'
在窗口中。包含列表框的Xaml文件也必须合并该资源字典。
<Window.Resources>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="clr-namespace: [namespace_from_your_referenced_library]">
</ResourceDictionary.MergedDictionaries>
</Window.Resources>
也可以从库中合并资源到代码后面(.xaml.cs)
例如，在下一个代码中，我们合并应用程序级别的资源
ResourceDictionary res = new ResourceDictionary();
res.Source = new Uri("LIBRARYNAME;fullclassname" + ".xaml", UriKind.Relative);
try{
Application.Current.Resources.MergedDictionaries.Add(res);
}
catch {
// may be resource was loaded ?
}
