Interface with multiple implementations in ninject

问题

I've got an interface that has two different implementations.

public interface IProducer
{
}

public class Producer : IProducer
{
}

public class FaultProducer : IProducer
{
}

I have two different classes that both take an IProducer as a dependency.

public class ConsumerChannel
{
    public ConsumerChannel(IProducer producer)
    {
    }
}

public class TradePublisher
{
    public TradePublisher(IProducer producer)
    {
    }
}

TradePublisher needs a Producer and ConsumerChannel needs a FaultProducer. I can only bind IProducer to one implementation. In Windsor I could do this with named bindings and Dependency.OnComponent but I can't find similar abilities in Ninject. Is there a way to inject specific dependencies in Ninject?

回答1:

Use named bindings for Ninject:

Bind<IProducer>().To<FaultProducer>().Named("FaultProducer");

public TradePublisher([Named("FaultProducer")] IProducer producer)
    //...
}
