Question

正如您所看到的，默认Aero主题中ListBoxItem的样式非常老式，所以我发现了一种新的样式，如果我把它放在MainWindow.Resources中就可以了。

但是如果我将它放在Themes/Aero.NormalColor.xaml的类库中并引用它（我也在该库中使用了一些自定义控件）但它不起作用。任何解决方法？：（

ThemeInfo用于类库：

[assembly: ThemeInfo(ResourceDictionaryLocation.SourceAssembly, ResourceDictionaryLocation.SourceAssembly)]

ThemeInfo主要项目：

[assembly: ThemeInfo(ResourceDictionaryLocation.None, ResourceDictionaryLocation.SourceAssembly)]

Themes/Aero.NormalColor.xaml：

</ResourceDictionary>

Answer 1

我想将这个'覆盖'应用于应用程序中的所有ListBoxItem，摆脱'x：Key =“{x：Type ListBoxItem}”'

Answer 2

在包含列表框的Window.xaml文件中，您还必须合并该resourcedictionary。

<Window.Resources>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="clr-namespace: [namespace_from_your_referenced_library]">
    </ResourceDictionary.MergedDictionaries>
</Window.Resources>

此外，您可以合并来自库中的资源（.xaml.cs）即在下一个代码中，我们合并了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 ?
}
