c# - 我可以像在 Autofac 中那样在 Unity 中的模块中注册我的类型吗？

Question

我对 Autofac 相当熟悉，我非常喜欢 Autofac 的一项功能是模块注册。有谁知道我如何使用 Unity 做到这一点？我很难找到在 Google 中使用哪些术语来得出统一等价物(如果有的话)。

public class Global : HttpApplication, IContainerProviderAccessor
{
   private static IContainerProvider _containerProvider;

   protected void Application_Start(object sender, EventArgs e)
   {
      var builder = new ContainerBuilder();
      builder.RegisterModule(new MyWebModule());

      _containerProvider = new ContainerProvider(builder.Build());
   }

[...]

   public IContainerProvider ContainerProvider
   {
      get { return _containerProvider; }
   }
}

public class MyWebModule: Module
{
    protected override void Load(ContainerBuilder builder)
    {
       builder.RegisterModule(new ApplicationModule());
       builder.RegisterModule(new DomainModule());
    }
}

public class ApplicationModule: Module
{
    protected override void Load(ContainerBuilder builder)
    {
       builder.Register(c => new ProductPresenter(c.Resolve<IProductView>()))
                .As<ProductPresenter>()
                .ContainerScoped();
    }
}

实际上，您可以使用 Unity 容器扩展轻松完成。

public class Global : HttpApplication, IContainerProviderAccessor
{
   private static IContainerProvider _containerProvider;

   protected void Application_Start(object sender, EventArgs e)
   {
      var container = new UnityContainer();
      container.AddNewExtension<MyWebModule>();

      _containerProvider = new ContainerProvider(container);
   }

[...]

   public IContainerProvider ContainerProvider
   {
      get { return _containerProvider; }
   }
}

public class MyWebModule : UnityContainerExtension
{
    protected override void Initialize()
    {
        Container.AddNewExtension<ApplicationModule>();
        Container.AddNewExtension<DomainModule>();
    }
}

public class ApplicationModule: UnityContainerExtension
{
    protected override void Initialize()
    {
        Container.RegisterType<ProductPrensenter>(
            new ContainerControlledLifetimeManager(),
            new InjectionFactory(c => new ProductPresenter(c.Resolve<IProductView>())));
    }
}
