autofac使用架构体现泛型注入

  /// <summary>
        /// 定义一个容器
        /// </summary>
        public static IContainer container { get; set; }

        /// <summary>
        /// 获取dal实例化对象
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <returns></returns>
        public static T Resolve<T>()
        {
            try
            {
                if (container == null)
                {
                    Initialise();
                }
            }
            catch (Exception ex)
            {
                throw new System.Exception("IOC实例化出错!" + ex.Message);
            }
            return container.Resolve<T>();
        }

        /// <summary>
        /// 初始化容器
        /// </summary>
        public static void Initialise()
        {
            var builder = new ContainerBuilder();
            builder.RegisterType<CommodityDAL>().As<ICommodityDAL>().InstancePerLifetimeScope();
            builder.RegisterType<StockDAL>().As<IStockDAL>().InstancePerLifetimeScope();
            container = builder.Build();
        }

　　调用

  private ICommodityDAL _commodityDAL = Container.Resolve<ICommodityDAL>();
