asp.net-mvc - 在 MVC 6 Controller 中创建 session (使用 View ，使用 Entity Framework )

Question

我正在尝试在我的 UserAccountsController 中创建一个 session

using System.Linq;
using Microsoft.AspNet.Mvc;
using Microsoft.AspNet.Mvc.Rendering;
using Microsoft.Data.Entity;
using POPPELWebsite.Models;

namespace POPPELWebsite.Controllers
{
    public class UserAccountController : Controller
    {

        public ActionResult Index()
        {
            return View();
        }

        public ActionResult Register()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Register(UserAccount account)
        {
            if (ModelState.IsValid)
            {
                using (OurDbContext db = new OurDbContext())
                {
                    db.userAccount.Add(account);
                    db.SaveChanges();
                }

                ModelState.Clear();
                ViewBag.Message = account.FirstName + " " + account.LastName + " successfully registered.";
            }

            return View();
        }

        //Login
        public ActionResult Login()
        {
            return View();
        }

        [HttpPost]
        public ActionResult Login(UserAccount user)
        {
            using (OurDbContext db = new OurDbContext())
            {
                var usr = db.userAccount.Single(u => u.Email == user.Email && u.Password == user.Password);
                if (usr != null)
                {
                    Session["UserID"] = usr.UserID.ToString;
                }
            }
        }

    }
}

我得到一个错误提示

the name Session does not exist in the current context.

我需要做这部分来完成一个mvc的注册登录教程

Session 属性在 MVC 6 的 Controller 类中不存在，而是使用 HttpContext.Session 访问 session 属性。

例如:

// get values
string strValue = HttpContext.Session.GetString("StringKey");
int intValue = HttpContext.Session.GetInt32("IntKey");
byte[] byteArrayValue = HttpContext.Session.Get("ByteArrayKey");

// set values
HttpContext.Session.Set("ByteArrayKey", byteArrayValue);
HttpContext.Session.SetInt32("IntKey", intValue);
HttpContext.Session.SetString("StringKey", strValue);
