我不明白为什么我会收到这个错误,请你帮我找一下我做错了什么？

我想用这个ViewModel实现的是因为我有许多记录使用相同的CartId将其用作父项,并将booking.Item.ItemName用作子项.

你能否告诉我,我试图做的方式是否正确？

控制器:

public ActionResult MyBookings()
{

    var myBookingList = SystemDB.Carts.Where(s => s.Booking.Login == strLoginName).OrderByDescending(s => s.RecordId).Take(10);


    List<MyBookingsViewModel> result = new List<MyBookingsViewModel>();
    foreach (var item in myBookingList)
    {
        MyBookingsViewModel model = new MyBookingsViewModel();

        model.Carts.RecordId = item.RecordId;
        model.Carts.CartId = item.CartId;
        model.Carts.Booking.Item.ItemName = item.Booking.Item.ItemName;
        model.Carts.Booking.UserFullName = item.Booking.UserFullName;
        model.Carts.Booking.RequestDate = item.Booking.RequestDate;
        model.Carts.StatusCode.StatusCodeName = item.StatusCode.StatusCodeName;
        result.Add(model);
    }


    return View(result);
}

模型:

public class MyBookingsViewModel
{
    public Cart Carts { get; set; }
    public List<Booking> Bookings { get; set; }
}

public class Cart …
