Question

我正在尝试构建我的用户存储库（实体框架）的Dependecy Injection，并使用它来帮助在我的MVC Web应用程序中创建角色。会员提供商似乎工作正常。

的Web.config：

<membership defaultProvider="MyMembershipProvider">
  <providers>
    <clear/>  
    <add name="MyMembershipProvider" type="MyApp.Infrastructure.Concrete.CustomMembershipProvider" />
  </providers>
</membership>

<roleManager enabled="true" defaultProvider="MyRoleProvider">
  <providers>
    <clear/>
    <add name="MyRoleProvider" type="MyApp.Infrastructure.Concrete.CustomRoleProvider" />
  </providers>
</roleManager>

我的Ninject模块：

internal class MyNinjectModules : NinjectModule
{
    public override void Load()
    {
        Bind<IUserRepository>().To<EFUserRepository>();
    }
}
public class MvcApplication : System.Web.HttpApplication
{
    private IKernel ninjectKernel = new StandardKernel(new MyNinjectModules());
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        ModelBinders.Binders.Add(typeof(Cart), new CartModelBinder());

        ninjectKernel.Inject(Membership.Provider);
        ninjectKernel.Inject(Roles.Provider);
    }
}

自定义会员提供商：

public class CustomMembershipProvider : MembershipProvider
{
    private static List<User> Users = new List<User>();

    [Inject]
    public IUserRepository userRepo { get; set; }

    public override bool ValidateUser(string username, string password)
    {
        Users = userRepo.Users.ToList();
        return Users.Exists(u => u.Name == username && u.Password == password);
    }
}

自定义角色提供者：

public class CustomRoleProvider : RoleProvider
{
    private static List<User> Users = new List<User>();

    [Inject]
    public IUserRepository userRepo { get; set; }

    public override string[] GetRolesForUser(string username)
    {
        //Hardcoded roles for known users
    }
}

像这样授权：

[Authorize(Roles="SiteAdministrator")]
public class AdminController : Controller
{
    //controller
}

之前我没有使用过依赖注入，但是我必须错误地绑定我的IUserRepository？我收到这个错误：

Error activating IUserRepository
No matching bindings are available, and the type is not self-bindable.
Activation path:
   2) Injection of dependency IUserRepository into parameter userRepo of constructor of type AdminController
   1) Request for AdminController

Ninject依赖注入以提供角色和成员资格
