ASP.NET MVC:如何将多个对象传输到View方法？

Question

我完成了NerdDinner教程,现在我正在玩一些项目.索引页面显示所有即将到来的晚餐:

    public ActionResult Index()
    {
        var dinners = dinnerRepository.FindUpComingDinners().ToList();
        return View(dinners);
    }

在DinnerRepository类我有方法FindAllDinners,我想添加到所有晚餐的索引方法编号,如下所示:

    public ActionResult Index()
    {
        var dinners = dinnerRepository.FindUpComingDinners().ToList();
        var numberOfAllDinners = dinnerRepository.FindAllDinners().Count();
        return View(dinners, numberOfAllDinners);
    }

当然,这不起作用.因为我对OOP很陌生,所以我需要帮助.

谢谢,
Ile

创建视图模型:

public class DinnerViewModel
{
    public List<Dinner> Dinners { get; set; }
    public int NumberOfAllDinners { get; set; }
}

public ActionResult Index()
{
    var dinners = dinnerRepository.FindUpComingDinners().ToList();
    var numberOfAllDinners = dinnerRepository.FindAllDinners().Count();
    return View(new DinnerViewModel { Dinners = dinners, NumberOfAllDinners = numberOfAllDinners } );
}
