对象上下文类MVC

Question

我正在尝试从MVC应用程序中的控制器访问对象上下文类ForestDBEntities - 模拟文件夹中的ForestDBEntities。但是，它似乎没有找到它。我错过了模型的命名空间吗？

这是代码：

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

namespace Forest.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

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

        //
        // GET: /Home/Details/5

        public ActionResult Details(int id)
        {
            return View();
        }

        //
        // GET: /Home/Create

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

        //
        // POST: /Home/Create

        [HttpPost]
        public ActionResult Create(FormCollection collection)
        {
            try
            {
                // TODO: Add insert logic here

                return RedirectToAction("Index");
            }
            catch
            {
                return View();
            }
        }

        //
        // GET: /Home/Edit/5

        public ActionResult Edit(int id)
        {
            return View();
        }

        //
        // POST: /Home/Edit/5

        [HttpPost]
        public ActionResult Edit(int id, FormCollection collection)
        {
            try
            {
                // TODO: Add update logic here

                return RedirectToAction("Index");
            }
            catch
            {
                return View();
            }
        }

        //
        // GET: /Home/Delete/5

        public ActionResult Delete(int id)
        {
            return View();
        }

        //
        // POST: /Home/Delete/5

        [HttpPost]
        public ActionResult Delete(int id, FormCollection collection)
        {
            try
            {
                // TODO: Add delete logic here

                return RedirectToAction("Index");
            }
            catch
            {
                return View();
            }
        }
    }

}
