Private IGradeService _ gradeService; public HomeController (IGradeService gradeService) {_ gradeService = gradeService;} public ActionResult Index () {var model = _ gradeService.GetAllGrade () .ToList (); return View (model);}

Modify Global.asax by adding the following code to the Application_Start () method, paying attention to referencing Autofac, Autofac.Integration.Mvc, and other references

Var builder = new ContainerBuilder (); builder.RegisterType (). As (). InstancePerHttpRequest (); var container = builder.Build (); DependencyResolver.SetResolver (new AutofacDependencyResolver (container)); / / automatic injection of var baseType=tyeOf (Idependency); var assemblys=AppDomain.currentDomain.getAssemblies (). Tolist (); builder.RegisterAssemblyTypes (assemblys.ToArry ()) .where (t+baseTye.IsAssignableFrom (t) & & tasking baseType) .AsImplementedInterfaces () .InstancePerLifetimeScope ()

Note: DependencyResolver.SetResolver (new AutofacDependencyResolver (container)); this must be placed after builder.RegisterControllers (Assembly.GetExecutingAssembly ());, or there will be an error: no argument constructor is defined for the object.
