Question

我需要显示工作机会的列表，但不显示下拉列表，而是显示foreach，以便显示所有要约，但不要让我在模型中出现GetEnumerator错误。如何显示清单？（具有OfertaPostulante的关系与OfertaLaboral和AspNetUsers）：

Controller OfertaPostulante / create

    public ActionResult Create()
    {
        ViewBag.OfPostUsr_ID = HttpContext.GetOwinContext().GetUserManager<ApplicationUserManager>().FindByName(User.Identity.Name).Email;
        ViewBag.OfPostOf_ID = new SelectList(db.OfertaLaboral, "Of_ID", "Of_Titulo");
        return View();
    }


    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "OfPost_ID,OfPostOf_ID,OfPostUsr_ID,OfPostFecha")] OfertaPostulante ofertaPostulante)
    {
        if (ModelState.IsValid)
        {
            db.OfertaPostulante.Add(ofertaPostulante);
            var Datetimenow = DateTime.Now;
            ofertaPostulante.OfPostFecha = new DateTime(Datetimenow.Year, Datetimenow.Month, Datetimenow.Day, Datetimenow.Hour, Datetimenow.Minute, 0);
            ofertaPostulante.OfPostUsr_ID = HttpContext.User.Identity.GetUserId();
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.OfPostUsr_ID = new SelectList(db.AspNetUsers, "Id", "Email", ofertaPostulante.OfPostUsr_ID);
        ViewBag.OfPostOf_ID = new SelectList(db.OfertaLaboral, "Of_ID", "Of_Titulo", ofertaPostulante.OfPostOf_ID);
        return View(ofertaPostulante);
    }

我需要在OfertaPostulante的“创建”视图中显示该列表，以便用户可以查看和选择要约

asp.net更改下拉列表到显示更多信息的块？
