来自数据库保存响应的问卷调查

Question

我在这里有4个模型类，我已经在html表单中提取问卷字段，问题和答案选项，我有一个控制器操作方法，我想发布这个问卷数据并保存响应和问卷详细信息。有人可以帮我吗？

public class Question
{
    public long? ParentId { get; set; }
    public long Id { get; set; }
    public long OrderNumber { get; set; }
    public string Text { get; set; }

    public List<AnswerOption> AnswerOptions { get; set; }
}

   public class AnswerOption
{
    public long Id { get; set; }
    public long QuestionId { get; set; }
    public string Option { get; set; }

}
   public class Response
{
    public long Id { get; set; }
    public long QuestionnaireId { get; set; }
    public long QuestionId { get; set; }
    public long AnswerId { get; set; }
    public string AnswerText { get; set; }
    public DateTime? CreatedOn { get; set; }

    public AnswerOption AnswerOption { get; set; }
    public Question Question { get; set; }
}
public class Questionnaire
{
    public long Id { get; set; }
    public string Email { get; set; }
    public string BusinessName { get; set; }
    public string DBA { get; set; }
    public string MailingAddress { get; set; }
    public string MailingCity { get; set; }
    public string MailingState { get; set; }
    public string MailingZip { get; set; }
    public DateTime? CreatedOn { get; set; }
    public string Signature { get; set; }
    public string Title { get; set; }
    public List<Response> Responses { get; set; }
}

这是Html，

@{ var questions = GetAllQuestions();
}

        @for (var i = 0; i < questions.Count; i++)
        {
            <span class="grid__col-2">
                <label class="text-large mb0">@questions[i].Text</label>
                <input type="hidden" name="Responses[@i].QuestionId" value="@questions[i].Id"/>
                <input type="hidden" name="Responses[@i].Id" value="@i"/>
                @foreach (var answerOption in questions[i].AnswerOptions)
                {
                    if (answerOption.Option != null)
                    {
                        <span>
                            <input type="radio" value="@answerOption.Option" name="@answerOption.QuestionId"/>

                        </span>

                    }
                    else if (answerOption.Option == null)
                    {
                        <span>

                            <input type="text" id="@answerOption.QuestionId" value=""/>
                        </span>
                    }
                }

            </span>
        }

    </div>
    <div class="panel-footer">
        <div class="form-group center">
            <button id="submitInfo" type="submit" class="btn btn-info">Submit Application</button>
        </div>
    </div>
</div>
</form>

这是我的控制器操作方法

    public IActionResult SubmitApplication(Questionnaire questionnaire)
    {
        var successSaveQuestionnaire = Base.RepoService.SaveQuestionnaire(questionnaire);
        return RedirectToAction("Index", successSaveQuestionnaire ? new { Message = FeedbackMessageEnum.SaveQuestionnaireSuccessEnum } : new { Message = FeedbackMessageEnum.SaveQuestionnaireFailedEnum });
    }
