1. Install

Install-Package AutofacInstall-Package Autofac.Extensions.DependencyInjection

2.Startup

2.1 增加成員

public IContainer ApplicationContainer { get; private set; }

2.2 Startup.ConfigureServices

返回值改為：IServiceProvider

末尾中增加：

//******************* autofac start ***********************
// Create the container builder.

var autofacBuilder = new ContainerBuilder();autofacBuilder.RegisterType<TCPCollectorApplicationService>().As<ITCPCollectorApplicationService>();
autofacBuilder.Populate(services);this.ApplicationContainer = autofacBuilder.Build();return new AutofacServiceProvider(this.ApplicationContainer);
//******************* autofac start ***********************

3. Usage

3.1 构造注入

直接構造注入即可使用。

public TodoController(IKnowledgeApplicationService knowledgeApplicationService, ITCPCollectorApplicationService tcpCollectorApplicationService, IServiceProvider serviceProvider){KnowledgeApplicationService = knowledgeApplicationService;TCPCollectorApplicationService = tcpCollectorApplicationService;ServiceProvider = serviceProvider;
}

3.2 使用ServiceProvider获取。

var tcpSvc = ServiceProvider.GetService(typeof(ITCPCollectorApplicationService)) as ITCPCollectorApplicationService;return Ok(tcpSvc.GetAll());
