如何將一個Ninjects服務注入到一個自制的RoleProvider類中？

Question

在實現Roleprovider的同時，它從數據庫中獲取角色。我一直得到一個對象沒有...異常的實例。

事實證明，ninject不會注入我的服務。

我試着把attribuut放在屬性頂部沒有成功。 我嘗試添加一個構造函數，但隨後即時得到的死亡黃屏告訴我應該有一個無參數的構造函數

代碼

Public Class AnipRolProvider 
    Inherits RoleProvider 
'this service needs to get initialized 
    Private _memberhip As IMemberschipService 

    Sub New() 
     'only this constructor is called by asp by default 
    End Sub 

    Sub New(memberschipservice As IMemberschipService) 
     'this constructor should be called but how ? 
     _memberhip = memberschipservice 
    End Sub 

的唯一方法，我需要

Public Overrides Function GetRolesForUser(username As String) As String() 
     If String.IsNullOrEmpty(username) Then 
      Throw New ArgumentException("username is nothing or empty.", "username") 
     End If 

     Return _memberhip.GetRolesForUser(username) 

    End Function 

怎麼辦我實施了ninjects，讓角色提供者與忍者合作？

其他信息：

<roleManager enabled="true" defaultProvider="AnipRoleProvider"> 
     <providers> 
     <clear/> 
     <add name="AnipRoleProvider" type="Anip.Core.AnipRolProvider" /> 
     </providers> 
    </roleManager> 

在我的web.config有到aniproleprovider參考。

offtopic-sidenote：在複製這些snipsets時，我應該學會寫更好的名字！

你必須註冊在global.ascx你IMembershipService，不知道如何在VB做把在C＃中，它看起來是這樣的：

kernel.Bind<IMembershipService>().To<MembershipService>().InRequestScope(); 

using System; 
using System.Collections.Generic; 
using System.Security.Principal; 
using System.Web; 
using System.Web.Mvc; 
using System.Web.Routing; 
using System.Web.Security; 
using Domain.Interfaces; 
using Domain.Models; 
using Domain.Storage; 
using Domain.Services; 
using Ninject; 
using Ninject.Syntax; 
using WebApp.Controllers; 
using WebApp.Mailers; 
using WebApp.ModelBinders; 

namespace WebApp 
{ 

    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 } // Parameter defaults 
     ); 

    } 

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

     kernel.Bind<ISession>().To<MongoSession>().InRequestScope(); 
     kernel.Bind<IAuthenticationService>().To<AuthenticationService>().InRequestScope(); 
     kernel.Bind<IMailer>().To<Mailer>().InRequestScope(); 
     kernel.Bind<IFileProvider>().To<MongoFileProvider>().InRequestScope(); 

     return kernel; 
    } 

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

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

}
