使用Ninject国际奥委会更换工厂 [英] Using Ninject IOC to replace a factory

问题描述

我有一个解析器内的工厂方法。从本质上讲，我加载一个令牌我仰望的处理程序令牌，或者通过对默认处理程序下降。我实现了这是一个开关和一个词典<字符串类型> 但是这两种方法需要我来存储映射其他地方比处理程序类。

I've got a factory method inside a parser. Essentially as I load a token I look up the handler for that token, or drop through to the default handler. I've implemented this as a switch and as a Dictionary<string,Type> but both approaches require me to store the mapping somewhere else than the handler class.

我们正在使用Ninject为国际奥委会等我我也可以用做

We are using Ninject for IOC and so I've realized I can also do it using

kernel.Get<ITokenHandler>(tokenName); 

但是，这并不救我存储在什么记号处理程序的信息，可以处理在2个地点。有没有一种方法，我可以装点处理程序，以便这一被自动映射？

but that doesn't save me storing the information on what token the handler can deal with in 2 locations. Is there a way I can decorate the handler so this gets mapped automatically?

推荐答案

如果我正确地按照你的问题，这听起来像要检索名为绑定。你没有提到你使用的是什么版本的Ninject，但基于您的代码段，我猜你正在使用Ninject 2.0。如果是这样的话，那么我认为这将足以为你的模块中绑定：

If I follow your question correctly, it sounds like you want to retrieve a named binding. You didn't mention what version of Ninject you are using, but based on your code snippet, I am guessing you are using Ninject 2.0. If that's the case then I would think this would suffice for your binding in your module:

Bind<ITokenHandler>().To<YourConcreteTypeHere>().Named(tokenName);

您尽可能多的具体类型绑定到相同的接口和名称区分它们，然后用检索它们你已经在你的问题中指定的确切语法。

You bind as many concrete types to the same interface and differentiate them by name, and then retrieve them using the precise syntax you've specified in your question.

如果我失去了一些东西的关键，让我知道。
