Asp.net mvc 如何在视图中使用MVC绑定选定的单选按钮值 正确答案 @RadioButton（x=>x.IsCorrectAnswerOption1，新的{@class=“form control”，@type=“radio”，id=“IsCorrectAnswerOption1”，name=“IsCorrectAnswerOption1”}） A. @RadioButton（x=>x.IsCorrectAnswerOption2，新的{@class=“form control”，@type=“radio”，id=“IsCorrectAnswerOption2”，name=“IsCorrectAnswerOption2”}） B @RadioButton（x=>x.IsCorrectAnswerOption3，新的{@class=“form control”，@type=“radio”，id=“IsCorrectAnswerOption3”，name=“IsCorrectAnswerOption3”}） C @（x=>x.IsCorrectAnswerOption4，新的{@class=“form control”，@type=“radio”，id=“IsCorrectAnswerOption4”，name=“IsCorrectAnswerOption4”}） D 需要正确的答案

在这个模型中，我有四个不同的单选按钮，具有不同的id和名称。我有一个真值，但在这里我无法绑定所选的单选值，即真值。

您可以为每个选项创建一个枚举，并将其作为模型中的属性。在post方法中，用户可以通过以下方式直接映射所选选项： MyOptions属性本身

注意：不要更改元素的name属性。

//您的cshtml页面
@模型答案；
@使用（Html.BeginForm（FormMethod.Post））
{
@（x=>x.MyOptions，Options.Option1）选项1
@（x=>x.MyOptions，Options.Option2）选项2
@（x=>x.MyOptions，Options.Option3）选项3
@（x=>x.MyOptions，Options.Option4）选项4
提交
}

使用帮助程序时，它应该自动在输出上创建适当的ID、类型和名称字段？我认为您不需要在options对象中设置它们。我已经尝试过这样@Html.RadioButton（x=>x.IsCorrectAnswerOption1，new{@class=“form control”}），但不起作用。您可以使用javascript进行设置。有人能提供解决方案吗？

//Your Model
public class Answer
{
   public Options MyOptions { get; set; }
}

public enum Options
{
  None,
  Option1,
  Option2,
  Option3,
  Option4,

}

//Your Controller

public ActionResult SelectOption()
{
    Answer ans = new Answer();

    return View(ans);
}

[HttpPost]
public ActionResult SelectOption(Answer answer)
{
    var selectedOption = answer.MyOptions;

    return View();
}
