在ASP.NET MVC 4视图中插入下拉列表，并且数据将来自另一个表

Question

我是ASP.NET的初学者，所以我可能有愚蠢的问题，但是我需要一些帮助。我有一个模型和控制器主，带有读/写规则。我在Main Controller中有一个创建动作，它有效，但是我需要该字段是下拉列表，并且可以从另一个部门表中进行选项。我已经搜索了答案，但是我没有得到完整的答案。因此，如果可以的话，请帮助我。如果需要，我将编写代码。非常感谢。

MainController

 public ActionResult Create()
        {
            return View();
        }
        //
        // POST: /Main/Create
        [HttpPost]
        public ActionResult Create(Main main)
        {
            if (ModelState.IsValid)
            {
                db.Main.Add(main);
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return View(main);
        }

main.cs(型号(

    namespace PhoneBook.Models
{
    public class Main
    {
        public int Id { get; set; }
