webform中使用webapi,并且使用autofac

       private void AutofacIoCRegister()
        {
            HttpConfiguration config = GlobalConfiguration.Configuration;

            if (_containerProvider != null)
                _containerProvider = null;
            var builder = new ContainerBuilder();
            builder.RegisterApiControllers(Assembly.GetExecutingAssembly());

            builder.RegisterGeneric(typeof(Repository<>)).As(typeof(IRepository<>));
            Type baseType = typeof(IDependency);
            var assemblies = System.Web.Compilation.BuildManager.GetReferencedAssemblies().Cast<Assembly>().ToList();
            builder.RegisterAssemblyTypes(assemblies.ToArray())
                .Where(type => baseType.IsAssignableFrom(type) && !type.IsAbstract)
                .AsSelf()   //自身服务，用于没有接口的类
                .AsImplementedInterfaces() //接口服务
                .PropertiesAutowired()  //属性注入
                .InstancePerLifetimeScope();    //保证生命周期基于请求

            IContainer container = builder.Build();
            _containerProvider = new ContainerProvider(container);

            config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
            //DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
        }

注意

IDependency 

builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
