Question

我为ASP.NET MVC 4网站创建了一个Controller，一个Model和一个View ... 但是，当我尝试显示名为GroupId的ViewBag时，它不在我看来！

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using AIO___Desafio_Interno_de_Inteligências.Models;

namespace AIO___Desafio_Interno_de_Inteligências.Controllers
{
    public class LoginController : Controller
    {
        //
        // GET: /Login/

        public ActionResult Login()
        {
            var detail = new Details()
            {
                GroupId = 23,
                GroupPassword = "280phcdd12",
            };
            return View();
            ViewBag.GroupId = detail.GroupId;
            ViewBag.GroupPassword = detail.GroupPassword;
        }

    }
}

而且，在我的查看代码中：

@{
    ViewBag.Title = "Login";
}

<h2>Login</h2>

<p>@ViewBag.GroupId</p>
<p>@ViewBag.GroupPassword</p>

但是，我得到的是：

Just my default CSS,and these codes,as H1 and P... But the ViewBag.{...} is not there

我的模型页面（Details.cs）：

namespace AIO___Desafio_Interno_de_Inteligências.Models
{
    public class Details
    {
        public int GroupId { get; set; }
        public string GroupPassword { get; set; }
    }
}

你的控制器方法应该是这样的

public ActionResult Login()
{
    var detail = new Details()
    {
        GroupId = 23,
        GroupPassword = "280phcdd12",
    };

    ViewBag.GroupId = detail.GroupId;
    ViewBag.GroupPassword = detail.GroupPassword;

    return View();
}

在返回视图之前设置ViewBag数据

我尝试在VIEW中显示VAR，但它没有显示NOTHING
