没有从View - MVC获得Radiobutton值

Question

关于是/否radiobutton答案我几乎没有问题。

我正在尝试将所选值（radiobutton值）保存到我的数据库中的Answers表中。但是所选的值将返回null。

查看

@using (Html.BeginForm("SaveAnswers", "MyController"))
    <td>@Html.RadioButtonFor(model => model.answerValue[i], true) Yes @Html.RadioButtonFor(model => model.answerValuer[i], false) No</td>
         <input type = "submit" name = "actionType" value = "SaveAnswers"/>

模型

Public List <bool> answerValue {get;set;}

控制器

public ActionResult SaveAnswers(string actionType)
    {
        Answers userAnswers = new Answers();

        if (ModelState.IsValid)
        {
            if (actionType == "Save")
            {
                    userAnswers.value = model.answerValue[i];
                    db.SaveChanges();
     }
        }
        return View(actionType);
    }

它没有在我的控制器中选择它并显示它的空...

请尝试将模型作为输入添加到控制器中，您需要将模型替换为模型的类名

public ActionResult SaveAnswers(string actionType, Model model)
   {
      Answers userAnswers = new Answers();

    if (ModelState.IsValid)
    {
        if (actionType == "Save")
        {
                userAnswers.value = model.answerValue[i];
                db.SaveChanges();
 }
    }
    return View(actionType);
}
