asp.net-mvc-4 – 如何实现自定义SiteMapNodeProvider

我正在尝试调整MvcSiteMapProvider以基于存储在数据库中的一些信息创建面包屑.

this帖子的答案听起来很有希望所以我实现了自己的SiteMapNodeProvider.但后来我不知道如何连接,所以使用新实现的SiteMapNodeProvider而不是静态xml文件(“Mvc.sitemap”).

当我在我的项目中使用SimpleInjector时,我在已经存在的注入初始化代码中调用了setup方法.

public static void Initialize()
    {
        Injection.Global = new Container();
        InitializeContainer(Injection.Global);
        Injection.Global.RegisterMvcControllers(Assembly.GetExecutingAssembly());
        Injection.Global.RegisterMvcAttributeFilterProvider();
        Injection.Global.Verify();
        DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(Injection.Global));
    }

    private static void InitializeContainer(Container container)
    {
        // Setup configuration of DI
        MvcSiteMapProviderContainerInitializer.SetUp(container);

        //... register some other stuff for my project here ...
    }

MvcSiteMapProviderContainerInitializer类由包创建：’Mvcsitemapprovider.mvc4.di.simpleinjector / 4.4.5′

有谁知道如何让我的项目使用新创建的SiteMapNodeProvider？
我在官方文件中找不到任何关于此的文件……

编辑：我尝试了你的建议(甚至删除旧的DI东西,只使用了nuget-package中的那个),但我仍然得到错误…
这是我在MvcSiteMapProviderContainerInitializer中的内容

但我仍然得到以下异常：
