Question

I am completely new to dependency injection. I am using asp mvc and ninject.
I extended a class from ‘DefaultControllerFactory’ and added following ‘AddBindings’ code:

private void AddBindings()
        {            
            ninjectKernel.Bind<ICitiesRepository>().To<CitiesRepository>().WithConstructorArgument(
                "connectionString", ConfigurationManager.ConnectionStrings["cstr"].ConnectionString);

            ninjectKernel.Bind<ICountriesRepository>().To<CountriesRepository>().WithConstructorArgument(
                "connectionString", ConfigurationManager.ConnectionStrings["cstr"].ConnectionString);

            ninjectKernel.Bind<IUserRepository>().To<UserRepository>().WithConstructorArgument(
                "connectionString", ConfigurationManager.ConnectionStrings["cstr"].ConnectionString);

        }

In my ‘AccountController’ I inject IUserRepository via contructor:

private IUserRepository userRepository;

        public AccountController(IUserRepository userRepository)
        {
            this.userRepository = userRepository;
        }

And here I come to issue. Account controller contains ‘RegisterUser’ action. And user must select with standard parameters (username, firstName etc.) a few additianal parameters like Country and City. How to inject more repository classes in some controller? What is the best strategy for this?
