Angular 依赖注入和.NetCore 的对比：

Angular	.Netcore	Example
Injector	ServiceProvider	constructor(injector: Injector) { this.localization = injector.get(LocalizationService); this.permission = injector.get(PermissionCheckerService); this.feature = injector.get(FeatureCheckerService); this.notify = injector.get(NotifyService); this.setting = injector.get(SettingService); this.message = injector.get(MessageService); this.multiTenancy = injector.get(AbpMultiTenancyService); this.appSession = injector.get(AppSessionService); this.elementRef = injector.get(ElementRef); this.modalHelper = injector.get(ModalHelper); }
@Injectable	自定义标签类上修饰	@Injectable() export class AppSessionService { private _user: UserLoginInfoDto; private _tenant: TenantLoginInfoDto; private _application: ApplicationInfoDto; 。。。 }
@Inject	自定义标签，参数上修饰	constructor(@Inject(HttpClient) http: HttpClient, @Optional() @Inject(API_BASE_URL) baseUrl?: string) { this.http = http; this.baseUrl = baseUrl ? baseUrl : ""; }
