我使用了NuGet Ninject MVC3扩展，但无法在请求时注入到控制器中。似乎没有绑定，因为MVC正在寻找无参数的构造函数。以下是堆栈跟踪：

我正在尝试注入的控制器（目前使用基类）：
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)
}
以下是我 NinjectWebCommon.cs 中相关的部分：
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>();
}
}
您可以在我的NinjectWebCommon.cs文件中看到星号标记的行，在那里我尝试显式构建控制器进行测试。这个控制器可以完美地工作，正常注入了Xml..Providers。
我错过了什么吗？我对NuGet MVC3扩展中发生的事情不太了解，因此不知道控制器绑定失败的具体原因。
如果您能提供一些指导，请告诉我，非常感谢！
