Modelbinding名单 [英] Modelbinding lists

问题描述

我得到了像

public class Question {   
   public int Id { get;set; }
   public string Question { get;set; }
   public string Answer { get;set; } 
}

public ActionResult Questions() 
{   
  return View(GetQuestions()); 
}

public ActionResult SaveAnswers(List<Question> answers) 
{  
  ... 
}

视图>如下：

<% for (int i = 0; i < Model.Count; i++) { %>   
 <div>
  <%= Html.Hidden(i.ToString() + ".Id") %>
  <%= Model[i].Question %>
  <%= Html.TextBox(i.ToString() + ".Answer") %>
 </div> 
<% } %>

显然，这种观点是行不通的。我只是无法访问视图列表中。

Obviously this view doesn't work. I'm just not able access the list in the view.

这也是过时的文件，它似乎周围很多modelbinding列表的功能，其中在测试改变。

The documentation for this also is outdated, it seem a lot of the functionality around modelbinding lists where changed in the beta.

推荐答案

答案是不使用HTML佣工。

the answer is not to use the html helpers.

<% for (int i = 0; i < Model.Count; i++) { %> 
  <div>
     <input type="hidden" name="answers[<%= i %>].Id" id="answers_<%= i %>_Id" value="<%= Model[i].Id %>" />
     <input type="text" name="answers[<%= i %>].Answer" id="answers_<%= i %>_Answer" value="<%= Model[i].Answer %>" />
  </div> 
<% } %>

不是很pretty，但作品。重要的是，姓名和身份证需要是不同的。
名称允许有[，]，但id是不是。

Not very pretty, but works. The important thing is that Name and Id need to be different. Name is allowed to have "[", "]" but id isn't.
