我如何Ninject在ASP.NET MVC Web应用程序工作？ [英] How do I work with Ninject in an ASP.NET MVC Web App?

问题描述

我创建了一个新的MVC的Web应用程序，我不得不Ninject.dll，Ninject.Web.Common.dll和Ninject.Web.MVC.dll引用。

的Global.asax.cs：

 公共类MvcApplication：NinjectHttpApplication
    {
        公共静态无效RegisterGlobalFilters（GlobalFilterCollection过滤器）
        {
            filters.Add（新HandleErrorAttribute（））;
        }        公共静态无效的RegisterRoutes（RouteCollection路线）
        {
            routes.IgnoreRoute（{}资源个.axd / {*} PATHINFO）;            routes.MapRoute（
                默认，//路线名称
                {控制器} / {行动} / {ID}，// URL带参数
                新
                {
                    控制器=家，
                    行动=索引，
                    ID = UrlParameter.Optional
                }）;
        }        保护覆盖的iKernel CreateKernel（）
        {
            VAR内核=新StandardKernel（）;
            kernel.Load（Assembly.GetExecutingAssembly（））;
            返回内核;
        }        保护覆盖无效OnApplicationStarted（）
        {
            base.OnApplicationStarted（）;            AreaRegistration.RegisterAllAreas（）;
            RegisterGlobalFilters（GlobalFilters.Filters）;
            的RegisterRoutes（RouteTable.Routes）;
        }
    }
 

App_start \\ NinjectWebCommon：

 公共静态类NinjectWebCommon
    {
        私人静态只读引导程序引导程序=新的引导程序（）;        ///＆LT;总结＆gt;
        ///启动应用
        ///＆LT; /总结＆gt;
        公共静态无效的start（）
        {
            DynamicModuleUtility.RegisterModule（typeof运算（OnePerRequestHttpModule））;
            DynamicModuleUtility.RegisterModule（typeof运算（NinjectHttpModule））;
            bootstrapper.Initialize（CreateKernel）;
        }        ///＆LT;总结＆gt;
        ///停止应用程序。
        ///＆LT; /总结＆gt;
        公共静态无效停止（）
        {
            bootstrapper.ShutDown（）;
        }        ///＆LT;总结＆gt;

            返回内核;
        }        ///＆LT;总结＆gt;

        ///＆LT; PARAM NAME =内核方式＆gt;内核＆LT; /参数＆GT;
        私有静态无效RegisterServices（内核的iKernel）
        {

    }
 

我得到错误的顺序不包含元素。我在做什么错了？

解决方案

您从 NinjectHttpApplication 导出，并且您使用 App_Start 在同一时间。选一个！阅读Ninject.MVC3 的实况获取更多信息。

I've created a new MVC Web application and I have references to Ninject.dll, Ninject.Web.Common.dll and Ninject.Web.MVC.dll.

Global.asax.cs:

public class MvcApplication : NinjectHttpApplication
    {
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new HandleErrorAttribute());
        }

        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new
                {
                    controller = "Home",
                    action = "Index",
                    id = UrlParameter.Optional
                });
        }

        protected override IKernel CreateKernel()
        {
            var kernel = new StandardKernel();
            kernel.Load(Assembly.GetExecutingAssembly());
            return kernel;
        }

        protected override void OnApplicationStarted()
        {
            base.OnApplicationStarted();

            AreaRegistration.RegisterAllAreas();
            RegisterGlobalFilters(GlobalFilters.Filters);
            RegisterRoutes(RouteTable.Routes);
        }
    }

App_start\NinjectWebCommon:

public static class NinjectWebCommon 
    {
        private static readonly Bootstrapper bootstrapper = new Bootstrapper();

        /// <summary>
        /// Starts the application
        /// </summary>
        public static void Start() 
        {
            DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
            DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
            bootstrapper.Initialize(CreateKernel);
        }

        /// <summary>
        /// Stops the application.
        /// </summary>
        public static void Stop()
        {
            bootstrapper.ShutDown();
        }

        /// <summary>
        /// Creates the kernel that will manage your application.
        /// </summary>
        /// <returns>The created kernel.</returns>
        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)
        {
        }        
    }

I get the error "The sequence contains no elements". What am I doing wrong?

Error details:

Description: An unhandled exception occurred during the execution of the current web request. Examine the stack trace for more information about this error and where it originated in the code.

解决方案

You are deriving from NinjectHttpApplication AND you are using App_Start at the same time. Choose one! Read the docu of Ninject.MVC3 for more info.
