jQuery Ajax MVC 4应用程序

我正在关注ASP中的Ajax和jQuery的博客。净MVC

My Model Class:

namespace Chekout.Models
{
    [Table(Name = "Products")]
    public class Product
    {
        [Column(IsPrimaryKey = true)]
        public int Id { get; set; }
        [Column]
        public string Name { get; set; }
        [Column]
        public string Description { get; set; }
        [Column]
        public decimal Price { get; set; }
        [Column]
        public int UnitsInStock { get; set; }
    }
}

我的控制器:

namespace Chekout.Controllers
{
    public class ProductController : Controller
    {  
        //dbContextDataContext is my dbml class which was not generated in the blog.   
        dbContextDataContext dbContext = null;
        public ProductController()
        {
            this.dbContext = new dbContextDataContext(Connection.connectionString);
        }
        //
        // GET: /Product/
        public ActionResult Index()
        {
            //Products[] product = dbContext.GetTable().ToArray(); 
              //The Above Statement gives me Error! Why? Am i not following the blog?
            return View();
        }
    }
}

我想选择，更新，插入，删除数据通过jquery ajax在MVC应用程序。我一直在关注上面的博客，但这对我没有帮助。请说明我做错了什么，或者我没有关注博客。

Products[] product = dbContext.GetTable<Products>().ToArray();
