类来管理顶级组件：
Controller我有一个public class FooViewModel {}
public class Controller
{
public FooViewModel Foo1ViewModel {get; protected set;} // = new ...;
}
的静态资源：
Controller我希望Windows和UserControls具有<Application.Resources>
<local:Controller x:Key="AppController" />
</Application.Resources>
的DataContext属性。
据我所知，是将DataContext设置为Controller本身（这不是我想要的）
Controller但是我不能将其设置为它的属性
<Window.DataContext>
<StaticResource ResourceKey="AppController" />
</Window.DataContext>
答案 0 :(得分：3)
使用Controller实例作为源的绑定：
<Window ...
DataContext="{Binding Foo1ViewModel, Source={StaticResource AppController}}">
答案 1 :(得分：1)
使用Binding：
<Window.DataContext>
<Binding Path="Foo1ViewModel" Source="{StaticResource AppController}" />
</Window.DataContext>
