我正在尝试从文本框中传递控制器中的值。我谷歌这个问题。但没有得到任何适合我的解决方案。下面是我的控制器。 网络产品控制器

在我的控制器中，我正在调用 Add() 方法。在行动结果中，它在控制器中传递值但不传递文本框值。当我尝试使用

@using (Html.BeginForm("Add", "WebProductController",FormMethod.Post))

然后表格不会t recognize my method when i use button to sending data in my form. i陷入这个问题。但没有解决方案:(

您的控制器应如下所示：

 public ActionResult Add(IList<ShoppingItemModel> items){
      foreach(ShopingItemModel item in items){
          if (item.Id != null){
               ShopingItem shopingItem = service.GetById(item.Id);
               ... Add Item to whatever
          }
      }
 }

您的 ShoppingItemModel：

public class ShoppingItemModel{
     [Required]
     public Id{get;set;}

     [Required]
     public Amount{get;set;}

     ...
}

您的观点（我跳过了 Java 脚本）：

 @model IList<ShoppingItemModel>

 <h2>Tablets</h2>
 @using (Html.BeginForm("Add", "WebProductController",FormMethod.Post)) {
 @Html.ValidationSummary(true)

 <table>
  <tr>
    <th>
        Name
    </th>
    <th>
        Price
    </th>
    ...
    <th>Amount</th>
</tr>

@for(int index; index < Model.Count; index++) {

  <tr>
    <td>
        @Html.HiddenFor(model => model[index].Id)
        @Html.DisplayFor(model => model[index].Name)
    </td>
    <td>
        @Html.DisplayFor(model => model[index].Price)
    </td>
    <td>
        @Html.DisplayFor(model => model[index].Batch)
    </td>
    ...
    <td>
        @Html.TextBoxFor(model => model[index].Quantity)
    </td>
  </tr>
}   
</table>   
<input type="submit" value="Add" />
}

这不是完整的解决方案。只是一个提示。托比
