我正在尝试将这个选定的单选按钮值从剃刀视图传递给控制器......有人可以告诉我如何做到这一点吗？...... ..... 我的观点是这样的：
@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" />
}
My Controller looks like this:.........
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();
}
}
These are the other methods:
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;
}

Add property:
添加属性：
public string SelectedAnswer { get; set; }
Add in view:
在视图中添加：
@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer1")
@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer2")
@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer3")
@Html.RadioButtonFor(m => m.SelectedAnswer, "Answer4")
In controller it postback the value according to selected radio button... i.e. either Answer1, or Answer2, etc.
在控制器中，它根据选定的单选按钮回发值......即 Answer1 或 Answer2 等。

If you are giving same name for your radio buttons, then you can try the following code
如果您为单选按钮指定相同的名称，则可以尝试以下代码
Controller
控制器
[HttpPost]
public ActionResult Index(string Answer)
{
return View();
}
View
看法
@using (Html.BeginForm("Index", "Demo"))
{
@Html.RadioButton("Answer", "A") <span>A</span>
@Html.RadioButton("Answer", "B") <span>B</span>
<input type="submit" value="Next" />
}
回答by Balaji Selvarajan
Use form collection
使用表单集合
[HttpPost]
public ActionResult Index(FormCollection fc)
{
string answerA = fc["Answer1"];
string answerB = fc["Answer2"];
string answerC = fc["Answer3"];
string answerD = fc["Answer4"];
return View();
}

Either make a hidden field for every radio button or change you radio buttons like this
要么为每个单选按钮创建一个隐藏字段，要么像这样更改单选按钮
@Html.RadioButtonFor("Answer1", new { @id = 1 })

I saw this on another thread and it work like a champ.
我在另一个线程上看到了这个，它像冠军一样工作。
Razor view like this:
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>
}
And Controller like this:
像这样的控制器：
public ActionResult test(string CashPayment)
{
//your code
}

Add the following source code to View:
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)
You can put the selected value to this HiddenField: @Html.HiddenFor(m=>m.Role)and send it to controller via [HttpPost] prototype.
您可以将选定的值放入此 HiddenField:@Html.HiddenFor(m=>m.Role)并通过 [HttpPost] 原型将其发送到控制器。
