将所选值从单选按钮传递到MVC中的控制器

Question

我正在尝试将此选定的单选按钮值从剃刀视图传递给控制器​​.... 有谁可以请你知道如何做到这一点？..................... 我的观点如下：

@using (Html.BeginForm("Index", "Exam"))
{

    @Html.Hidden("qid", Model.ID, new { @id = "id" })
    <table>
        <tr>
            <td>
                @Model.ID
            </td>
            <td>
                @Model.QuestionDes
            </td>
        </tr>
        <tr>
            <td>
                <p>@Html.RadioButton("Answer1", new { @id = 1 })  @Model.Answer1 </p>
            </td>
        </tr>
        <tr>
            <td>
                <p>@Html.RadioButton("Answer2", new { @id = 2 })  @Model.Answer2 </p>
            </td>
        </tr>
        <tr>
            <td>
                <p>@Html.RadioButton("Answer3", new { @id = 3 })  @Model.Answer3 </p>
            </td>
        </tr>
        <tr>
            <td>
                <p>@Html.RadioButton("Answer4", new { @id = 4 })  @Model.Answer4 </p>
            </td>
        </tr>

    </table>

    <input type="submit" value="Next" />

}
@using (Html.BeginForm("PrevIndex", "Exam"))
{

    @Html.Hidden("qid1", Model.ID, new { @id = "id1" })
    <input value="Prev" type="submit" />
}

我的控制器看起来像这样：.........

 public class ExamController : Controller
    {
        [HttpGet]
        public ActionResult Index()
        {
            IQuestionService ser = new QuestionService();
            QuestionLoadDTO q = ser.GetIndividualQuestions(1);
            return View(q);
        }

        [HttpPost]
        public ActionResult Index(QuestionLoadDTO ques)
        {
            int count = 0;
            count = int.Parse(Request["qid"].ToString());
            count++;
            if (count <= 4)
            {
                IQuestionService ser = new QuestionService();
                QuestionLoadDTO q = ser.GetIndividualQuestions(count);
                return View(q);
            }
            return RedirectToAction("Submit");

        }
        public ActionResult PrevIndex(QuestionLoadDTO ques)
        {
            int count1 = 0;
            count1 = int.Parse(Request["qid1"].ToString());
            count1--;
            if (count1 < 5 || count1 >= 0)
            {
                IQuestionService ser = new QuestionService();
                QuestionLoadDTO q = ser.GetIndividualQuestions(count1);
                return View("Index", q);
            }
            return RedirectToAction("End");

        }
        public ActionResult Submit()
        {
            return View();
        }
        public ActionResult End()
        {
            return View();
        }




    }

这些是其他方法：

QuestionLoadDTO IQuestionService.GetIndividualQuestions(int index)
{
    IQuestionData ser = new QuestionRepository();           

    QuestionLoadDTO q = ser.GetIndividualQues(index);

    return q;
}
public QuestionLoadDTO GetIndividualQues(int index)
{
    Context con = new Context();
    Question question = con.Questions.Find(index);//Where(e => e.ID == index).FirstOrDefault();
    QuestionLoadDTO dto = new QuestionLoadDTO()
    {
        ID = question.ID,
        QuestionDes = question.QuestionDes,
        Answer1 = question.Answer1,
        Answer2 = question.Answer2,
        Answer3 = question.Answer3,
        Answer4 = question.Answer4

    };                                
    return dto;
}

谢谢!!!!

Answer 1

添加属性：

public string SelectedAnswer { get; set; }

添加视图：

@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer1")
@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer2")
@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer3")
@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer4")

在控制器中，它根据所选的单选按钮回发值...即Answer1或Answer2等。

Answer 2

如果您为单选按钮指定相同名称，则可以尝试以下代码

<强>控制器

[HttpPost]
public ActionResult Index(string Answer)
{
    return View();
}

查看

@using (Html.BeginForm("Index", "Demo"))
{
       @Html.RadioButton("Answer", "A") <span>A</span> 
       @Html.RadioButton("Answer", "B") <span>B</span> 

    <input type="submit" value="Next" />
}

Answer 3

为每个单选按钮创建一个隐藏字段或更改像这样的单选按钮

@Html.RadioButtonFor("Answer1", new { @id = 1 })

Answer 4

使用表单集

[HttpPost]
    public ActionResult Index(FormCollection fc)
    {

      string answerA = fc["Answer1"];
      string answerB = fc["Answer2"];
      string answerC = fc["Answer3"];
      string answerD = fc["Answer4"];
      return View();
    }

Answer 5

将以下源代码添加到View：

@Html.RadioButtonFor(m => m.Role, "1" ) <span>A</span>
@Html.RadioButtonFor(m => m.Role, "0" ) <span>B</span>
@Html.HiddenFor(m=>m.Role)

您可以将选定的值放入此HiddenField：@Html.HiddenFor(m=>m.Role)，然后通过[HttpPost]原型将其发送到控制器。

Answer 6

我在另一个线程上看到了它，它像冠军一样工作。

像这样的剃刀视图：

@using (Html.BeginForm("test", "testcontroller"))
{
  @Html.RadioButton("CashPayment", "1")<span>Yes</span>
  @Html.RadioButton("CashPayment", "0")<span>No</span>
}

和像这样的控制器：

public ActionResult test(string CashPayment)
{   
   //your code
}
