将模型从视图传递到控制器时出现问题

Question

I bind my Checkout View with a Model which I'd like to pass to my Purchase controller to bind to my Purchase View. At the moment when it gets passed, the value is null.

What am I doing wrong?

Checkout View:

@model List<BasketModels.Product>

@using (Html.BeginForm("Purchased", "Basket", FormMethod.Post))
{

// problem here
    <input type="submit" value="Purchase"/>
}

Purchase controller:

[HttpPost]
        public ActionResult Purchased(List<BasketModels.Product> products)

Product mode:

public class BasketModels
    {
        public class Product
        {
            public int ID { get; set; }
            public string Name { get; set; }
            public string Description { get; set; }

            [DisplayFormat(DataFormatString = "{0:N}", ApplyFormatInEditMode = true)]
            public decimal UnitPrice { get; set; }

            public string ImageURL { get; set; }

            [Display(Name = "Quantity")]
            public int Quantity { get; set; }


            public int Stock { get; set; }

            [DisplayFormat(DataFormatString = "{0:N}", ApplyFormatInEditMode = true)]
            public decimal Price { get; set; }

            [DisplayFormat(DataFormatString = "{0:N}", ApplyFormatInEditMode = true)]
            public decimal TotalPrice { get; set; }
        }
}

Answer 1

You can use @Html.HiddenFor(x=>x.modelPropery) quick and dirty route. This is in adittion to your DisplayFor.

Answer 2

I tested it using the following and it works.

Checkout View

@model ProjectName.Models.BasketModels.Product

@using (Html.BeginForm("Purchased", "Basket", FormMethod.Post))
{
    @Html.TextBoxFor(m=>m.Description)
    <input type="submit" value="Purchase"/>
}

Purchased Controller

[HttpPost]
public ActionResult Purchased(BasketModels.Product products)
{
     return View();
}

I realize you might still want it to bind as a list. In that case, I've been trying to figure how to do that for days and I don't have a solution. List<string> works. List<model> does not.
