Enterprise Library: Unity of the few notes

 

Background

 

In . Net platform , almost all aspects of the registration Ioc container inconsistent with Unity requires attention to several issues , we verify by experiment .

 

verify the contents :

 

  Get
1. collection .
  
2. lifecycle management.

15             UnityContainer container = new UnityContainer(); 
16  
17             container.RegisterType<ITest, Test>(new PerThreadLifetimeManager()); 
18             container.RegisterType<ITest, TestA>("A"); 
19             container.RegisterType<ITest, TestB>("B"); 
20             container.RegisterType<ITest, Test>("C"); 
21             container.RegisterType<Test, Test>(); 
22             container.RegisterType<IOther, Test>(); 
23  
24             Console.WriteLine(container.ResolveAll<ITest>().Count()); 
25             //输出：3 
26  
27             Console.WriteLine(container.Resolve<ITest>().GetHashCode()); 
28             Console.WriteLine(container.Resolve<ITest>().GetHashCode()); 
29  
30             Console.WriteLine(container.Resolve<Test>().GetHashCode());

35             //输出：上边六行输出内容一样 
36  
37             Console.WriteLine(container.ResolveAll<ITest>().Last().GetHashCode()); 
38             Console.WriteLine(container.ResolveAll<ITest>().Last().GetHashCode()); 
39             //输出：输出两行完全不一样

43     public interface ITest { } 
44  
45     public interface IOther { } 
46  
47     public class Test : ITest, IOther { } 
48  
49     public class TestA : ITest { } 
50  
51     public class TestB : ITest { } 
52 }

 

 

output

 

 

Conclusion

 

  
1. ResolveAll returns only the name registered .
  
2. life cycle and the names of specific types + Registration of a relationship .
 

 

Notes

 

using Unity for specific types are not registered , some Ioc container requires that all types must be registered in order to obtain .
