Question

我正在将我的ASP.Net应用程序从MC3转换为MVC4。我有来自旧MVC3天的Simpleinjector代码，如下所示

WebContainer.Instance.Container.GetInstance<Func<HttpRequestBase>>();

现在这行代码在新的SimpleInjector版本2.8.0中抛出异常。我的应用程序在.Net framework 4.0中。请告知下面的堆栈跟踪

Message: No registration for type Func could be found.

Exception type: SimpleInjector.ActivationException
Stack Trace: 
at SimpleInjector.Container.ThrowMissingInstanceProducerException(Type serviceType)

 at CMS.PortalControls.CMSWebPartZone.LoadWebPart(Control container, CMSWebPartZone zone, WebPartInstance part, Boolean reloadData, Boolean isVariant)

WebContainer的代码如下所示

     this.Container = new Container();
        SimpleInjectorWebInitializer.Initialize();
        this.Container.RegisterPackages(GetAssemblies());
        this.Container.RegisterMvcControllers(Assembly.GetExecutingAssembly());
        this.Container.RegisterMvcIntegratedFilterProvider();
        this.RegisterGlobalFilters();

        //this.Container.Verify();
        DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(this.Container));
        //this.VerifyPages();

此功能的注册如下

 container.RegisterPerWebRequest<Func<HttpRequestBase>>(() => () => new HttpRequestWrapper(HttpContext.Current.Request));

将委托注入服务
