使用工厂时,WindsorContainer是否可以通过解析树传递对象

我遇到这样的问题:

public interface IBaseVMFactory
{
  public BaseVm Create(TransientDependency otherVM);
}

public class BaseVM
{
   BaseVM(ChildVM1 child1, ChildVM2 child2)
}

public class ChildVM1
{
   ChildVM1(TransientDependency otherVM)
}

我的所有viewModels(..VM)都需要是瞬态的。我需要让childVM1获得与工厂相同的otherVM实例。

我尝试将BaseVm注册为ScopedLifestyle,并手动实现工厂并在解析范围内时传递实例。 但是在解析时我仍然得到了另一个VM的新实例。

我错过了一些明显的东西吗?

我尝试使用以下代码复制您的Windsor 3.2问题:

using System.Diagnostics;
using Castle.Facilities.TypedFactory;
using Castle.MicroKernel.Registration;
using Castle.Windsor;

namespace ConsoleApplication2
{
    public class SomeViewModel
    {
        public SomeViewModel(ISomeFactory factory)
        {
            var dependency1 = factory.CreateSomeDependency();
            var dependency2 = factory.CreateSomeDependency();

            Debug.Assert(dependency1 != dependency2);
            Debug.Assert(dependency1.Dep == dependency2.Dep);
        }
    }

    public class SomeDependency
    {
        private readonly DepDep _dep;

        public SomeDependency(DepDep dep)
        {
            _dep = dep;
        }

        public DepDep Dep
        {
            get { return _dep; }
        }
    }

    public class DepDep
    {
    }

    public interface ISomeFactory
    {
        SomeDependency CreateSomeDependency();
    }

    class Program
    {
        static void Main(string[] args)
        {
            var container = new WindsorContainer();
            container.AddFacility<TypedFactoryFacility>();
            container.Register(
                Component.For<SomeViewModel>().LifestyleTransient(),
                Component.For<SomeDependency>().LifestyleTransient(),
                Component.For<DepDep>().LifestyleBoundTo<SomeViewModel>(),
                Component.For<ISomeFactory>().AsFactory().LifestyleTransient()
                );
            container.Resolve<SomeViewModel>();
        }
    }
}

令我惊讶的是,这才有效。因此,工厂似乎正在接管其创建环境的范围。我希望这会对你有所帮助。

亲切的问候, Marwijn。
