将含有所有已注册的实现接口的可枚举 [英] Injecting an Enumerable containing all registered Implementations of an Interface

问题描述

由于以下接口：

 公共接口IMyProcessor 
 {
无效处理（）; 
} 
  

我想可以注册多个实现，并有我的DI容器注入他们的枚举到这样一个类：

 公共类MyProcessorLibrary 
 {
私人只读IMyProcessor [] _processors; 
 
公共MyProcessingThing（IMyProcessor []处理器）
 {
 this._processors =处理器; 
} 
 
公共无效ProcessAll（）
 {
的foreach（在this._processors VAR处理器）
 {
 processor.Process（） ; 
} 
} 
} 
  

这可能吗？我目前的实施 MyProcessorLibrary 查找所有的 IMyProcessor 实现静态，但我宁愿做，如果通过一个容器我可以。我使用Unity，但很好奇，如果其他容器支持。

编辑：

感谢迄今答案;要清楚我要注入 MyProcessorLibrary 到另一个类，并将其建成了依赖对象的树，如：

$ B $布线的一部分b

 公共类MyProcessorRepository 
 {
公共MyProcessorRepository（MyProcessorLibrary processorLibrary）
 {
} 
} 
 
公共类MyProcessorService 
 {
公共MyProcessorService（MyProcessorRepository processorRepository）
 {
} 
} 
 
变种集装箱=新UnityContainer（）; 
 //注册一堆IMyProcessors的... 
 
 VAR的服务= container.Resolve< MyProcessorService>（）; 
  

解决方案

我不能统一发言，因为我不T选用它，但它肯定是可能的 Ninject （见的多次注射），我确实使用。

Given the following interface:

public interface IMyProcessor
{
    void Process();
}

I'd like to be able to register multiple implementations and have my DI container inject an enumerable of them into a class like this:

public class MyProcessorLibrary
{
    private readonly IMyProcessor[] _processors;

    public MyProcessingThing(IMyProcessor[] processors)
    {
        this._processors = processors;
    }

    public void ProcessAll()
    {
        foreach (var processor in this._processors)
        {
            processor.Process();
        }
    }
 }

Is this possible? My current implementation of MyProcessorLibrary looks up all the IMyProcessor implementations statically, but I'd rather do it through a container if I can. I'm using Unity, but am curious if other containers support it.

Edit:

Thanks for the answers so far; to be clear I want to inject MyProcessorLibrary into another class, and have it built as part of the wiring up of a tree of dependent objects, e.g.

public class MyProcessorRepository
{
    public MyProcessorRepository(MyProcessorLibrary processorLibrary)
    {
    }
}

public class MyProcessorService
{
    public MyProcessorService(MyProcessorRepository processorRepository)
    {
    }
}

var container = new UnityContainer();
// Register a bunch of IMyProcessors...

var service = container.Resolve<MyProcessorService>();

解决方案

I can't speak for Unity as I don't use it but it is definitely possible with Ninject (see Multi Injection) which I do use.
