使用参数的FluentValidation Validator

Question

我有一个FluentValidation验证器，我想用它来验证预订。在预订时，您必须选择在您选择的旅游中作为可用房型存在的房型。我需要从服务中获取可用的房间类型，并传递游览的代码。处理旅行代码所需的最佳方法是什么？

到目前为止我得到了什么：

public class BookingValidator : AbstractValidator<Booking>, IBookingValidator

public BookingValidator()
{
    RuleFor(booking => booking.Rooms).SetValidator(new RoomValidator())
}

public class RoomValidator : AbstractValidator<Room>

public RoomValidator()
{
    //validate that room.Type (eg. TWIN) exists in availableRoomTypes (eg List<string> {'SINGLE','TWIN'}
}

有些人在解决这个问题：

public class BookingValidator : AbstractValidator<Booking>

//should/can i pass in arguments here when IoC container is wiring up IBookingValidator to BookingValidator? Seems awkward
public BookingValidator(string tourCode)
{

//if so, use argument to get available room types, pass to RoomValidator
var availableRooms = RoomTypeService.GetAvailableRoomTypesForTour(tourCode);

RuleFor(booking => booking.Rooms).SetValidator(new RoomValidator(availableRooms))

//alternatively, tourCode is available from booking - is there some way to pass it to RoomValidator?
RuleFor(booking => booking.Rooms).SetValidator(new RoomValidator(),booking => booking.TourCode);

//Or is there some way I should be using .Must() or Custom()??

}

所以主要的问题是如何或在哪里将巡回代码送入验证器......？
