我有一個模塊,它爲某些特定類型(如ILog)進行屬性注入。繼承兒童生命週期範圍內的autofac模塊

protected override void AttachToComponentRegistration(IComponentRegistry componentRegistry, IComponentRegistration registration) 
{ 
     registration.Activated += [doing property injection]; 
} 

它在同一範圍內工作正常,但在孩子的範圍,AttachToComponentRegistration不會被觸發了,我必須爲了使財產注射重新註冊模塊。

所以我的問題是如何繼承註冊模塊在兒童生存期範圍?或者有沒有其他辦法可以做到這一點?

class Program 
{ 
    static void Main(string[] args) 
    { 
     var builder = new ContainerBuilder(); 
     builder.RegisterModule(new TestModule()); 
     builder.RegisterType<Test>().As<ITest>(); 
     var container = builder.Build(); 

     container.Resolve<ITest>().Say(); // output test11111 

     var scope = container.BeginLifetimeScope("nested", b => 
                  { 
                   // b.RegisterModule(new TestModule()); 
                   b.RegisterType<Test2>().As<ITest2>(); 
                  }); 

     scope.Resolve<ITest>().Say(); 
     scope.Resolve<ITest2>().Say(); 
    } 
} 

public interface ITest 
{ 
    void Say(); 
} 

public class Test : ITest 
{ 
    public void Say() 
    { 
     Console.WriteLine("test1111111"); 
    } 
} 

public interface ITest2 
{ 
    void Say(); 
} 

public class Test2 : ITest2 
{ 
    public void Say() 
    { 
     Console.WriteLine("test2222222"); 
    } 
} 

public class TestModule : Module 
{ 
    protected override void AttachToComponentRegistration(Autofac.Core.IComponentRegistry componentRegistry, Autofac.Core.IComponentRegistration registration) 
    { 
     Console.WriteLine("called for " + registration.Activator.LimitType); 
     base.AttachToComponentRegistration(componentRegistry, registration); 
    } 
}

你在做什麼Autofac版本? –

存在一個可能相關的問題:http://code.google.com/p/autofac/issues/detail?id=218 ...另外,您可以發佈在子範圍中創建/註冊組件的代碼?謝謝! –

Nicholas,請查看上面的源代碼,「調用」不出現嵌套的作用域組件。 –
