MVC传递IEnumerable< CustomVM>到控制器 [英] MVC passing IEnumerable<CustomVM> to Controller

问题描述

有人可以帮助我解决此问题吗?我想将自定义viewmodel的ienumerable或只是简单列表传递给控制器​​.有我的代码:

Can someone help me to solve this problem. I want to pass ienumerable or just simple list of my custom viewmodel to controller. Theres my code:

@model IEnumerable<WebWareApp.ViewModels.OstukorvVM>
@{
ViewBag.Title = "Ostukorv";
 }
 <h2>Hetkel ostukorvis olevad tooted:</h2>
 @using (Html.BeginForm("Create", "ToodeTellimuses"))
 {  @Html.AntiForgeryToken()
<table>
<tr>
    <th>Tootenimi</th>
    <th>Tootegrupp</th>
    <th>Tootja</th>
    <th>Mõõdud</th>
    <th>Varvus</th>
    <th>Hind</th>
    <th>Vali Kogus</th>
    <th></th>
</tr>
@{if (Model != null)
  {

  foreach (var item in Model)
  {<tr>
      <td>
          @Html.DisplayFor(modelitem => item.Toode.Nimi)
          @Html.HiddenFor(modelitem => item.Toode.Nimi)
      </td>
      <td>
          @Html.DisplayFor(modelitem => item.Toode.Tootegrupp.Nimetus)
          @Html.HiddenFor(modelitem => item.Toode.Tootegrupp.Nimetus)
      </td>
      <td>
          @Html.DisplayFor(modelitem => item.Toode.Tootja)
           @Html.HiddenFor(modelitem => item.Toode.Tootja)
      </td>
      <td>
          @Html.DisplayFor(modelitem => item.Toode.Pikkus) x  @Html.DisplayFor(modelitem => item.Toode.Laius) x  @Html.DisplayFor(modelitem => item.Toode.Korgus)
       @Html.HiddenFor(modelitem => item.Toode.Pikkus)  @Html.HiddenFor(modelitem => item.Toode.Laius)   @Html.HiddenFor(modelitem => item.Toode.Korgus)
      </td>
      <td>
          @Html.DisplayFor(modelitem => item.Toode.Varvus)
            @Html.HiddenFor(modelitem => item.Toode.Varvus)
      </td>
      <td>
          @Html.DisplayFor(modelitem => item.Toode.Hind)
          @Html.HiddenFor(modelitem => item.Toode.Hind)
      </td>
      <td>
          @Html.EditorFor(modelitem => item.kogus)

      </td>
      <td>
          @String.Format("Laos olemas {0}",item.Toode.Kogus)
          @Html.HiddenFor(modelitem => item.Toode.Kogus)
         </td>
      </tr>
      }
    }}
    </table>
<input type="submit" value="Telli">
 }

但是问题是当我调试控制器时，传入的模型字段始终为null.如有必要，我也可以将我的viewmodel和模型以及控制器发布到此处.

But the problem is that in my controller when i debugg the incoming model fields are always null.If necessary i can post my viewmodel and models and controller to here also.

推荐答案

用 for 循环替换 foreach 循环即可解决问题.

Replacing the foreach loop with a for loop will do the trick.

for (var i = 0; i < Model.Count; i++)  {
   @Html.HiddenFor(m => Model[i].Toode.Value)
}
