问题描述

我有一项服务，需要注入多个提供者，例如，请参见下文.如何使用Unity来实现此功能?

I have a Service that need inject more than one provider, see below for example. How to use Unity to implement this feature?

{
    public MyService(IEnumerable<Provider> Providers);
}

推荐答案

我知道这是一个老问题，但这也许会帮助其他偶然发现此问题的人.

I know this is an old question, but maybe this will help someone else that stumbles upon this.

只要使用特定名称注册实现，就可以轻松注入.然后，您将获得所有注册的实现.

As long as you register the implementations with a specific name, this is possible to easily inject. You will then get all registered implementations.

public class MyService: IMyService
{
    public MyService(IProvider[] providers)
    {
       // Do something with the providers
    }
}

只需确保将它们作为数组注入即可. Unity将理解这一点.当您注册它们时，您可以这样注册它们:

Just make sure to inject them as an array. Unity will understand this. And when you register them you can register them as such:

container.RegisterType<IProvider, FooProvider>("Foo");
container.RegisterType<IProvider, BarProvider>("Bar");
