在 asp.net mvc 4 视图中插入下拉列表，数据将来自另一个 table

Question

我是 asp.net 的初学者，所以我可能有愚蠢的问题，但我需要一些帮助。我有一个模型和控制器 MAIN，具有 read/write 规则。我在 MainController 中有一个创建操作，它可以工作，但我需要其中一个字段是下拉列表，并且它有来自部门的另一个 table 的选项。我已经搜索了答案，但没有得到完整的答案。所以如果可以的话，请帮助我。如果需要我会写代码。非常感谢。

主控制器

 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; }
        public string F_L_Name { get; set; }
        public string Regioni { get; set; }
        public string Raioni { get; set; }
        public string Department { get; set; }
        public string Division { get; set; }
        public string Position { get; set; }
        public string Mobile { get; set; }
        public string I_Phone { get; set; }
        public string Email { get; set; }
        public int Deleted { get; set; }
        public string Comment { get; set; }
        public string All_In_One { get; set; }
        public DbSet<Department> DepartmentFI { get; set; }
    }
}

Create.cshtml（查看）

    @model PhoneBook.Models.Main

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

Answer 1

像这样使用将部门显示为下拉列表

@Html.DropDownListFor(模型=>model.Department,模型=>model.Departments)

注意：您需要使用 controller/service

中数据库 table 的值填充 model.Departments

在 asp.net mvc 4 视图中插入下拉列表，数据将来自另一个 table

insert dropdown in asp.net mvc 4 view, and the data will be from another table

razor
