c# – 自定义表面控制器Umbraco问题

首先,我想澄清一点,我只是在学习ASP MVC和Umbraco :).可能有非常新手的错误.
我正在努力建立一个采访系统.在互联网上搜索,我找到了一个改变口味的例子.
我创建了一个用于测试的空项目,这就是我所拥有的.

            foreach (var currentPoll in testPage.Where("Active"))
            {
                questions.Add(new PollViewModel { ID = currentPoll.ID,Title = currentPoll.Name.ToString(),Answers = AnswerList(currentPoll.ID) });
            }

            return PartialView("~/Views/Polls.cshtml",questions);
        }

        private List<Answer> AnswerList(int myQuestionID)
        {
            var questionPage = Umbraco.Content(myQuestionID);
            var answers = new List<Answer>();

            foreach (var currentAnswer in questionPage.Children)
            {
                answers.Add(new Answer { ID = currentAnswer.ID,Text = currentAnswer.Name.ToString() });
            }

            return answers;

    }
}

模型

namespace Polls.Models
{
    public class Answer
    {
        public int ID { get; set; }
        public string Text { get; set; } // --> No use for now
    }
}

namespace Polls.Models

        public string Title { get; set; } // --> No use for now
        public List<Answer> Answers { get; set; }

    }

PartialView“民意调查”

@model IEnumerable<Polls.Models.PollViewModel>

<div>
    @using (Html.BeginUmbracoForm<Polls.Controllers.PollsController>("Submit"))
    {

        foreach (var item in Model)
        {
            <div>
                @Html.Hidden(item.ID.ToString())
                <p>
                    <strong>@item.Title</strong>
                </p>
                @{
            foreach (var answerItem in item.Answers)
            {
                <div>
                    @Html.RadioButton(item.Title,answerItem.ID,new { @id = answerItem.ID })
                    @Html.Label(answerItem.Text,new { @for = answerItem.ID })
                </div>
            }
                }
            </div>
        }

        <div>
            <button type="submit">Send...</button>
