Question

我正在使用ASP.NET MVC5 我想存储包含以下内容的问题列表：

问题本身
正确答案
错误答案清单。

我不确定在视图中将所需数据从表单传递到JobPostViewModel中的List<Question>jobQuestions，以满足我的需求需要什么代码。

这些是我所做的代码：

public class JobPostViewModel
{
    public class Question
    {
        public string theQuestion { get; set; }
        public string RightAnswer { get; set; }
        public List<string> WrongAnswers { get; set; }
    }

    public List<Question>jobQuestions { get; set; }
}

我尝试了很多方法，例如：

<div class="form-group">
     <div class="col-md-10">
          @Html.TextBoxFor(model => model.jobQuestions.FirstOrDefault().theQuestion, new { @class = "form-control", })
          @Html.TextBoxFor(model => model.jobQuestions.FirstOrDefault().RightAnswer, new { @class = "form-control", })
          @Html.TextBoxFor(model => model.jobQuestions.FirstOrDefault().WrongAnswers, new { @class = "form-control", })
          @Html.TextBoxFor(model => model.jobQuestions.FirstOrDefault().WrongAnswers, new { @class = "form-control", })
          @Html.TextBoxFor(model => model.jobQuestions.FirstOrDefault().WrongAnswers, new { @class = "form-control", })
</div>

但它没有按照我的预期发挥作用。

我知道可以这样做：

public class JobPostViewModel
{
    public string question1 { get; set;}
    public string correctAnswer1 { get; set;}
    public List<string>IncorrectAnswers1 { get; set;}
    public string question2 { get; set;}
    public string correctAnswer2 { get; set;}
    public List<string>IncorrectAnswers2 { get; set;}
}

以及我需要做的观点：

@using (Html.BeginForm()) 
{
    @Html.TextBoxFor(model => model.question1, new { @class = "form-control", })
    @Html.TextBoxFor(model => model.correctAnswer1 , new { @class = "form-control", })
    @Html.TextBoxFor(model => model.IncorrectAnswers1 , new { @class = "form-control", })
    @Html.TextBoxFor(model => model.IncorrectAnswers1 , new { @class = "form-control", })
    @Html.TextBoxFor(model => model.IncorrectAnswers1 , new { @class = "form-control", })

    @Html.TextBoxFor(model => model.question2, new { @class = "form-control", })
    @Html.TextBoxFor(model => model.correctAnswer2 , new { @class = "form-control", })
    @Html.TextBoxFor(model => model.IncorrectAnswers2 , new { @class = "form-control", })
    @Html.TextBoxFor(model => model.IncorrectAnswers2 , new { @class = "form-control", })
    @Html.TextBoxFor(model => model.IncorrectAnswers2 , new { @class = "form-control", }) 

    <p>
       <input type="submit" value="Save" />
   </p>
}

但这绝对不是一个好主意，尤其是如果我要收集数百个问题。

感谢您的任何建议！

使用现有的Question模型，这样的东西会起作用。

@using (Html.BeginForm()) 
{
    @Html.TextBoxFor(model => model.question, new { @class = "form-control", })
    @Html.TextBoxFor(model => model.correctAnswer , new { @class = "form-control", })

    @for (int i = 0; i < Model.WrongAnswers.Count; i++)
    {
        @Html.TextBoxFor(model => model.WrongAnswers[i], new { @class = "form-control", })
    }
