啓動時參數計數不匹配

Question

我得到的參數計數不匹配，除非在Startup.cs代碼完成執行後。如果在啓動類的退出時失敗。但我無法弄清楚代碼的下一步。它不去我的控制器。

public partial class Startup 
    { 
     public void Configuration(IAppBuilder app) 
     { 
      var container = SimpleInjectorInitializer.Initialize(app); 
      ConfigureAuth(app, container); 
     } 
    } 

Startup.Auth

public partial class Startup 
    { 
     // For more information on configuring authentication, please visit http://go.microsoft.com/fwlink/?LinkId=301864 
     public void ConfigureAuth(IAppBuilder app, Container container) 
     { 
      app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create); 
      app.CreatePerOwinContext(() => container.GetInstance<ApplicationUserManager>()); 
      app.UseCookieAuthentication(new CookieAuthenticationOptions 
      { 
       AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie, 
       LoginPath = new PathString("/Account/Login"), 
       Provider = new CookieAuthenticationProvider 
       { 
        OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
         validateInterval: TimeSpan.FromMinutes(30), 
         regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager)) 
       } 
      }); 
      app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie); 
      app.UseTwoFactorSignInCookie(DefaultAuthenticationTypes.TwoFactorCookie, TimeSpan.FromMinutes(5)); 
      app.UseTwoFactorRememberBrowserCookie(DefaultAuthenticationTypes.TwoFactorRememberBrowserCookie); 
     } 
    } 

堆棧跟蹤：

我剛剛完成我的登記管理ASP.NET.Identity，然後我收到此錯誤。

任何人都知道爲什麼？

在簡單的注射器取出WebActivator大會

namespace WebApplication1.App_Start 
{ 
    using System.Reflection; 
    using System.Web.Mvc; 

    using SimpleInjector; 
    using SimpleInjector.Extensions; 
    using SimpleInjector.Integration.Web; 
    using SimpleInjector.Integration.Web.Mvc; 
    using Owin; 
    using Models; 
    using Microsoft.AspNet.Identity; 
    using Microsoft.AspNet.Identity.EntityFramework; 
    using Microsoft.Owin.Security.DataProtection; 
    using Microsoft.AspNet.Identity.Owin; 
    using Microsoft.Owin.Security; 
    using SimpleInjector.Advanced; 
    using Microsoft.Owin; 
    using System.Web; 
    using System.Collections.Generic; 

    public static class SimpleInjectorInitializer 
    { 
    } 

它想看起來像上面的代碼

在您的噴射器的發動機罩它被稱爲

System.Reflection.MethodBase.Invoke(Object obj, Object[] parameters) 

兩個參數，第一個是在其上調用方法的目標實例和第二個是的方法參數陣列。

我們不知道您的上下文，但問題來自方法參數數組。這種不匹配發生在那裏。有參數計數不匹配。

使用調試，並根據您的上下文查看發生這種情況並修復它。
