如何将项目集合传递给Views模型？

Question

我正在使用MVC 3.我修改了注册新用户时使用的标准RegisterModel，方法是添加类型为OwnerApartments的ICollection属性。正在注册的用户可以将一个或多个公寓添加到集合中。在我的视图中，公寓通过模态窗体添加到视图中的html表格中。我的问题：当我将表单数据提交给控制器时，如何添加公寓（在html表中保存）。

   public class RegisterModel
{
    [Required]
    [Display(Name = "User Name")]
    public string UserName { get; set; }

    [Required]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "Email Address")]
    public string Email { get; set; }

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm password")]
    [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }

    [Required]
    [Display(Name = "First Name")]
    public string FirstName { get; set; }

    [Required]
    [Display(Name = "Last Name")]
    public string LastName { get; set; }

    [Required(ErrorMessage = "At least one Apartment must be added.")]
    public virtual ICollection<OwnerApartment> OwnerApartments { get; set; }
}

@model TestForum.Models.RegisterModel
@{
ViewBag.Title = "Register Account";
}
