我使用了 NuGet Ninject MVC3 扩展，但无法根据请求将其注入(inject) Controller 。它似乎没有绑定(bind)，因为 MVC 正在寻找无参数构造函数。这是堆栈跟踪:

    [MissingMethodException: No parameterless constructor defined for this object.]
       System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) +0

       System.Web.Mvc.DefaultControllerActivator.Create(RequestContext requestContext, Type controllerType) +67

    [InvalidOperationException: An error occurred when trying to create a controller of type 'MyApp.Presentation.Controllers.SearchController'. Make sure that the controller has a parameterless public constructor.]

我正在尝试注入(inject)的 Controller (目前需要一个基类):

public class SearchController : MainBaseController
{

    private readonly MyApp.Domain.Tutor.TutorSearch TutorSearch;
    protected static readonly log4net.ILog _log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

    [Ninject.Inject]
    public SearchController(MyApp.Domain.Tutor.TutorSearch tutorSearch)
    {
        this.TutorSearch = tutorSearch;
    }

    .... (no other constructors)
}

以及我的 NinjectWebCommon.cs 的相关部分:

    private static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
        kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

        RegisterServices(kernel);
        return kernel;
    }

    /// <summary>
    /// Load your modules or register your services here!
    /// </summary>
    /// <param name="kernel">The kernel.</param>
    private static void RegisterServices(IKernel kernel)
    {
        INinjectModule[] modules = new INinjectModule[]
        {
            new Domain.DomainModule()
        };

        kernel.Load(Assembly.GetExecutingAssembly());
        kernel.Load(modules);

        kernel.Bind<MyApp.Domain.Tutor.TutorSearch>().ToSelf();

        // ***************
        var t = kernel.Get<MyApp.Presentation.Controllers.SearchController>();
    }

最后，这是 DomainModule:

public class DomainModule : NinjectModule
{
    public override void Load()
    {
        Bind<Data.Profile.IProfileProvider>().To<Data.Profile.XmlProfileProvider>();
        Bind<Data.Subject.ISubjectProvider>().To<Data.Subject.XmlSubjectProvider>();
    }
}

正如您在我的 NinjectWebCommon.cs 中标有星号的行中看到的那样，我已尝试显式构建 Controller 作为测试。使用正确注入(inject)的 Xml..Providers，这工作得很好。

有什么我遗漏的吗？我对 NuGet MVC3 扩展背后发生的事情知之甚少，因此不知道 Controller 绑定(bind)在哪个点失败。

非常感谢任何关于要看什么的指示，谢谢。

最佳答案

经过一段时间的拼命修补，我终于找到了我的问题。 我引用了 MVC4 (System.Web.Mvc) DLL，并且没有将旧版 3.0.0.0 的绑定(bind)重定向到 4.0.0.0:

  <dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0" newVersion="4.0.0.0" />
    <bindingRedirect oldVersion="2.0.0.0" newVersion="4.0.0.0" />
    <!-- The following line was missing -->
    <bindingRedirect oldVersion="3.0.0.0" newVersion="4.0.0.0" /> 
  </dependentAssembly>

至少，我希望这是一个不错的解决方案。

编辑:如下所示，以下行更简洁:

  <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
