IoC实践--用Autofac实现MVC5.0的IoC控制反转方法

public interface IProductRepository
 {
        IQueryable<Product> Products { get; }
}

public class EFProductRepository : IProductRepository
 {
        private EFDbContext context = new EFDbContext();
        public IQueryable<Product> Products
        {
            get { return context.Products; }
        }
｝

public class BuyController : Controller
{
 private IProductRepository repository;
 public BuyController(IProductRepository repo)
 {
  repository = repo;
 }
