流畅验证使用LINQ let

我试图创建一个验证规则，我可以在两个参数传递到一个方法调用Must()

我的模型;

public class Make
{
    public int MakeId { get; set; }
    public string Name { get; set; }
    public Car[] Cars { get; set; }
}
public class Car
{
    public int CarId { get; set; }
    public string Name { get; set; }
}

验证器

public class MakeValidator : AbstractValidator<Make>
{
    public MakeValidator()
    {
        When(car => car.Cars != null && car.Cars.Any(), () =>
        {               
            RuleFor(car => car.Car)
                .Must(car => ValidateCar(car.CarId, MakeId)
                .WithMessage("Invalid Car");
        });
    }
    public bool ValidateCar(Car[] Cars, int makeId)
    {
        foreach (var car in Cars)
        {
            // *** internal logic ***
        }
        return true;
    }
}

Must((y, x) => 

Must(x =>

.Must((car, make) => ValidateCarMake(make, car.CarId)

RuleFor(car => car.Makes)
     .Must((car, make) => ValidateCarMake(make, car.CarId)
     .WithMessage("Invalid Car Make");

RuleFor(car => car.Make)
      .Must((car, make) => ValidateCarMake(car.Makes, car.CarId)
      .WithMessage("Invalid Car Make");
