如何将其他属性绑定到DropdownListFor？

Question

在以下代码中，提交表单时，所选国家/地区的ID正确传递回控制器。但是，我也想传递国家名称。如何将名称和ID一起发送回控制器？

模型

public class MyModel
{
    public Country Country { get; set; }
    public List<Country> CountryList { get; set; }
}

public class Country
{
    public int? ID { get; set; }
    public string Name { get; set; }    
}

查看

@using (Html.BeginForm())
{
   <div>
        @Html.DropDownListFor(m => m.Country.ID,
        new SelectList(Model.CountryList, "ID", "Name"))
   </div>

}

控制器

MyModel model = new MyModel();

public ActionResult Index()
{
    using (var service = new Service())
    {
        model.CountryList = service.GetCountries();

        return View(model);
    }
}

public ActionResult Index(MyModel tmpModel)
{
   return RedirectToAction("Index");
}
