如何以相同的形式向数据库输入多个记录

Question

我有这些表

• Survey：SurveyId，UserId，QuestionId，Answer，Comment
• User：UserId，Name
• Question：QuestionId，QuestionText

如何为1位用户制作表格以回答所有问题（90个问题）并在db中保存答案和评论？

SurveysController：

public class SurveysController : Controller

    private OrganizationASEMEntities1 db = new OrganizationASEMEntities1();

    // GET: Surveys
    public ActionResult Index()
    {

        return View(surveys.ToList());
    }

    // GET: Surveys/Details/5
    public ActionResult Details(int? id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Survey survey = db.Surveys.Find(id);
        if (survey == null)
        {
            return HttpNotFound();
        }
        return View(survey);
    }

调查视图Create：

@model OrganizationASEM.Models.Survey

@{
    ViewBag.Title = "Create";
}
