c# – 2个模型选择字符串

我试图用visual studio 2010学习自己的C#MVC4.

我想要做的是在某人用户名上选择的1个视图上获得2个模型的完整输出.

所以如果我去/团队/细节/ 1
我将从模特队员和球队获得所有信息.

楷模：

public class Players
{
    public int ID { get; set; }
    public string Name { get; set; }
    public int price { get; set; }
    public string coach { get; set; }
    public string Team { get; set; }
}

    public class Teams
{
    public int ID { get; set; }
    public string Name { get; set; }
    public string coach { get; set; }
}

        [HttpPost]
        public ActionResult Create(Teams teams)
        {
            if (ModelState.IsValid)
            {
                teams.coach = User.Identity.Name;
                db.Teams.Add(teams);
                db.SaveChanges();
                return RedirectToAction("Index");

        {

            if (teams == null)
            {
                return HttpNotFound();

            Teams teams = db.Teams.Find(id);
            if (teams == null)
            {
                return HttpNotFound();
            }
            return View(teams);
        }

        //
        // POST: /Teams/Delete/5

        [HttpPost,ActionName("Delete")]
        public ActionResult DeleteConfirmed(int id)
        {
            Teams teams = db.Teams.Find(id);
            db.Teams.Remove(teams);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        protected override void dispose(bool disposing)
        {
            db.dispose();
            base.dispose(disposing);
        }
    }
}

我绝对怎么做到这一点,我已经尝试了一个viewmodel类,但我不知道如何获得someones教练名称的这些信息.

我期待着您的回复.

解决方法

有很多方法可以让这只猫受到伤害,但你要首先看到的一件事就是你不会发回两个模型的一个实例.如果检查“详细信息”操作的代码：

public ActionResult Details(int id = 0)
{
    Teams teams = db.Teams.Find(id);
    if (teams == null)
    {
        return HttpNotFound();
    }
    return View(teams);
}

显然,我们发回的所有内容都是团队模型的一个实例.那么,让我们检查一下我们的选项.请考虑以下代码：

public ActionResult Details(int id = 0)
{
    Teams teams = db.Teams.Find(id);
    if (teams == null)
    {
        return HttpNotFound();
    }

    // get the list of players into a List<Players>
    var players ...

    var model = new Tuple<Teams,List<Players>>(teams,players);

    return View(model);
}

现在在视图中我们可以将我们的模型设置为此(请注意,您需要在@model声明中完全限定团队和玩家)：

@model Tuple<Teams,List<Players>>

从那里我们可以做以下事情：

Model.Item1.Name

要么：

Model.Item2[0].Name;
