是否可以在Unity中创建循环引用的对象？

Question

public interface IBaz { IBar bar { get; set; } } 
public class Baz : IBaz 
{ 
    public IBar bar { get; set; } 
    public Baz(IBar bar) { this.bar = bar; } 
} 

public interface IBar { IBaz baz { get; set; } } 
public class Bar : IBar 
{ 
    public IBaz baz { get; set; } 
    public Bar(IBaz baz) { this.baz = baz; } 
} 

class Program 
{ 
    static void Main(string[] args) 
    { 
     IUnityContainer container = new UnityContainer(); 

     container.RegisterType<IBar, Bar>(new ContainerControlledLifetimeManager()); 
     container.RegisterType<IBaz, Baz>(new ContainerControlledLifetimeManager()); 

     //Problem 1: I get a stack-overflow, but I am using the singleton lifetime manager? 
     var bar = container.Resolve<IBar>(); 
     var baz = container.Resolve<IBaz>(); 

     //Problem 2: I want Unity to do this automatically for me. How? 
     bar.baz = baz; baz.bar = bar; 

     var result = object.ReferenceEquals(bar, baz.bar) && object.ReferenceEquals(baz, bar.baz); 
    } 

Answer 1

不，现在还没有。在设置所有属性之前，该对象不被视为“构造”，因此它不会存储在生命期管理器中，直到发生此情况。在这种情况下会导致堆栈溢出。
