什么是Container.GetAllInstances< T>在NInject中? [英] What is the equivalent of Container.GetAllInstances<T> in NInject?

问题描述

我正在使用NInject构建消息代理，我需要在实现Consumes的容器中找到所有实例，该接口将类标记为能够使用特定消息类型.

I'm building a message broker with NInject, and I need to find all instances in the container that implement Consumes, an interface that marks the class as being able to consume a particular message type.

是否支持这种情况?

推荐答案

内特的回答:

多分辨率(通过GetAll)是 目前还不是多态的.那意味着 它只会考虑绑定 从您指定的确切接口. 如果您这样做:

Multi-resolution (via GetAll) is currently not polymorphic. That means that it will only consider bindings from the exact interface you specify. If you do this:

kernel.Bind<IWorker>().To<WorkerA>();
kernel.Bind<IWorker>().To<WorkerB>();
kernel.Bind<IWorker>().To<WorkerC>();

然后:

kernel.GetAll<IWorker>();

它将返回3个项目.但是，即使 如果IWorkerA，IWorkerB和 IWorkerC实施IWorker， Ninject不会查看来自 当您询问时，从IWorkerA到WorkerA 用于IWorker.

It will return 3 items. However, even if IWorkerA, IWorkerB, and IWorkerC implement IWorker, Ninject will not look at bindings from IWorkerA to WorkerA when you ask for IWorker.
