我有这个动作方法

[HttpPost]
public ActionResult CreateEsf(EsfLotDetailsModel model)
{
   ...
}

我在这个模型中有两个属性。一个是数据库 POCO 对象，另一个是列表。在此方法的 GET 等效项中，这些值都已正确填充，但在发布时这些值设置为 null（POCO）和空（列表）。

为什么会这样？

我的观点在这里

@using UI.Helpers

@model UI.Areas.Admin.Models.EsfLotDetailsModel

@{
    ViewBag.Title = "Create Forward Lot";

}

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Content/AdminDesignTheme/js/wl_Date.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Content/AdminDesignTheme/js/wl_Time.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.mousewheel.min.js")" type="text/javascript"></script>

@{
        <script type="text/javascript">
            $(document).ready(function () {
                var options = {
                    dateFormat: "dd/mm/yy"
                };
                $('#Starts').wl_Date(options);
                $('#Ends').wl_Date(options);
                $('#startTime').wl_Time();
                $('#endTime').wl_Time();
            });
        </script>
}

将 FormMethod = FormMethod.Post 添加到您的 Html.BeginForm()

@using (Html.BeginForm("Action", "Controller",FormMethod.Post))
{

}

你的提交按钮在哪里？

@using (Html.BeginForm("Action", "Controller",FormMethod.Post))
{
  ...
  <input type="submit" value="submit" />
}

填写表格时，按提交按钮，然后在[HttpPost]方法中输入Model的值。

这些选项都不起作用。我将 POCO 对象中的所有值分别放在模型中，并删除了 POCO 对象。不知道为什么它不起作用。
