ninject继承接口

Question

我有两个基本的接口如下，一个继承另一个。我为他们结合实现如下..

public interface IUnitOfWork { } 
public interface IEventStoreUnitOfWork : IUnitOfWork { } 

public class TransactionalHandler<TCommand, TCommandHandler> { 
    public TransactionalHandler(IUnitOfWork unitOfWork) { 
      // removed 
    } 
} 

public class EventStoreUnitOfWork : IEventStoreUnitOfWork { } 

绑定...

Bind<IEventStoreUnitOfWork>().To<EventStoreUnitOfWork>(); 

Bind<TransactionalHandler<IDomainCommand, IDomainCommandHandler<IDomainCommand>>>() 
    .ToSelf() 
    .WithConstructorArgument("unitOfWork", Kernel.GetService(typeof(IEventStoreUnitOfWork))); 

这是行不通的。错误是：

Error activating IUnitOfWork 
No matching bindings are available, and the type is not self-bindable. 
Activation path: 
2) Injection of dependency IUnitOfWork into parameter unitOfWork of constructor of type TransactionalHandler{CreateUserCmd, CreateUserCmdHandler} 
1) Request for TransactionalHandler{CreateUserCmd, CreateUserCmdHandler} 

这是怎么回事？显然，IUnitOfWork由IEventStoreUnitOfWork继承，并且具有绑定。我事件尝试了这一点，但我得到了同样的错误...

Bind<TransactionalHandler<IDomainCommand, IDomainCommandHandler<IDomainCommand>>>() 
.ToSelf() 
.WithConstructorArgument("unitOfWork", Kernel.GetService(typeof(IEventStoreUnitOfWork)) as IUnitOfWork); 

任何想法？

谢谢

Answer 1

该类型必须完全匹配。这意味着你需要绑定IUnitOfWork。搜索依赖关系时不考虑基本类型。

亚伦詹森有ninject叉它在github上认为基本类型，如果你是绝对需要这种行为
