MVC模型绑定和下拉列表

下面显示了一个个人类。在视图中,我需要显示它的属性,以及存在于其他表中的DepartmentName。下面类中的DepartmentID是一个外键。我正在使用Linq to SQL。我还将在下面显示我的个人存储库和控制器代码。我需要在索引视图页面中显示部门名称,并在编辑视图页面上显示下拉列表。我是MVC新手,所以我不知道该怎么做。任何帮助都非常感谢。

public class Person_Validation
{
    [HiddenInput(DisplayValue = false)]
    [ScaffoldColumn(false)]
    public object PersonId { get; set; }

    [HiddenInput(DisplayValue = false)]
    [ScaffoldColumn(false)]
    public object DepartmentId { get; set; }

    [DisplayName("First Name")]
    [Required(ErrorMessage = "First Name is required")]
    [StringLength(50, ErrorMessage = "Frist Name cannot be more than 50 characters")]
    public object FirstName { get; set; }

    [DisplayName("Last Name")]
    [Required(ErrorMessage = "Last Name is required")]
    [StringLength(50, ErrorMessage = "Last Name cannot be more than 50 characters")]
    public object LastName { get; set; }

    [HiddenInput(DisplayValue = false)]        
    public object Active { get; set; }

    [HiddenInput(DisplayValue = false)]
    public object DateAdded { get; set; }

    [HiddenInput(DisplayValue = false)]
    public object DateDeleted { get; set; }

    public IEnumerable<Department> departments { get; set; }             
}

PersonRepository类 :

public IList<Person> GetAllPersons()
{
    //get all active people
    var activePeople = from p in db.Persons
                       where p.Active == true
                       select p;

    return activePeople.ToList();            
}

控制器代码:

public ActionResult Index(int? page)
{
    const int pageSize = 25;

    var persons = _repository.GetAllPersons();            
    var paginatedPersons = new PaginatedList<Person>(persons, page ?? 0, pageSize);

    return View(paginatedPersons);
}
