与Steven Sanderson的BeginCollectionItem进行模型绑定并不起作用

Question

我正在尝试构建一个动态的System.DateTime列表，该列表也绑定到包含其他属性的模型。简化模型如下所示：

public class MAbsence : ModelBase<MAbsence, Absence>
{

    public MAbsence ()
    {
        ExtraDates = new List<DateTime>();
    }

    ....

    [Display(Name = "Date extra")]
    public List<DateTime> ExtraDates { get; set; }
}

我使用局部视图渲染ExtraDates，它看起来像这样：

@model System.DateTime

@{
Random rand = new Random();
var Index = rand.Next();
 }
@using(Html.BeginCollectionItem("ExtraDates")){
<div class="ExtraDate" id="@Index">


<div class="form-group form-group-default " id="@Index">
    @Html.LabelFor(model => model.Date)

    <input name="Date" id="Date_@Index" type="text" class="form-control value="@Model.ToString("dd.MM.yyyy")"/>

    @Html.ValidationMessageFor(M => M.Date, null, new { @class = "error" })
</div>

<a href="#" class="deleteRow">delete</a>

</div>
}

在[HttpPost]动作中，我试图将模型和模型以及IEnumerable ExtraDates作为参数，但它们都没有获得任何值。它们都是空的。

[HttpPost]

    public ActionResult AbsenceAdd(MAbsence model, IEnumerable<DateTime> ExtraDates)
    {
      ... code that should process the list of dates and the MAbsence model. Both lists model.ExtraDates and ExtraDates are null.
    }

我错过了什么？
