不復雜的Autofac注入

private static void SetAutofacWebAPI()
        {
            var builder = new ContainerBuilder();
            
            #region 配置註冊方法
            string dataType = ConfigurationManager.AppSettings["dataBaseType"].ToString().ToLower();
            //var data = Assembly.Load("Model");//加載特定程序集
            var data2 = Assembly.Load("MvcAdmin.Service");//加載特定程序集
            switch (dataType)
            {
                case "mssql":
                    builder.RegisterAssemblyTypes(data2)
                        .Where(a => a.FullName.Contains("MvcAdmin.Service.MSSQLServer")).AsImplementedInterfaces();
                    break;
                case "mysql":
                    builder.RegisterAssemblyTypes(data2)
                        .Where(a => a.FullName.Contains("MvcAdmin.Service.MySQLServer")).AsImplementedInterfaces();
                    break;
                default:
                    //builder.RegisterAssemblyTypes(data)
                    //    .Where(a => a.FullName.Contains("Model.MYSQL")).AsImplementedInterfaces();
                    builder.RegisterAssemblyTypes(data2)
                        .Where(a => a.FullName.Contains("MvcAdmin.Service.MySQLServer")).AsImplementedInterfaces();
                    break;
            }
            #endregion

            builder.RegisterControllers(Assembly.GetExecutingAssembly());
            var container = builder.Build();
            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
           
        }

看得出，去就是在web.config中加了一個數據庫的選擇，不加的話也會有默認的。以前有人說我用web.config配置太複雜了，全部出這篇。

上面的代碼我在以前開源的小後臺中有使用，地址：http://code.taobao.org/p/MvcAdmin/src/能夠去看看裏面的啓動項代碼

另外在附上Autofac入門：
