Castle Windsor 无法注入接口类型数组

问题描述

我有一个类在构造函数中接受一个接口数组:

I have a class that takes an array of interfaces in the constructor:

public class Foo<T1, T2> : IFoo<T1, T2>
{
    public Foo(IBar[] bars)
    {
        ...
    }
}

我的容器注册如下所示:

My container registration looks as follows:

container.Register(AllTypes.Pick().FromAssemblyNamed("...")
                    .WithService.FirstInterface());
container.AddComponent("foo", typeof(IFoo<,>), typeof(Foo<,>));

我有几个 IBar 的实现，容器可以明确地定位它们，因为调用 ServiceLocator.Current.GetAllInstances() 工作正常.

I have several implementations of IBar, and the container can definately locate them, as calling ServiceLocator.Current.GetAllInstances<IBar>() works fine.

但是，如果我尝试获取 IFoo 的实例，它会抛出一个异常，表示它无法满足 deoendency...未注册".

如果我将构造函数更改为采用 IBar 的单个实例，则它可以正常工作.

If I change the constructor to take a single instance of IBar it works fine.

有什么想法吗?

推荐答案

添加 ArrayResolver:

Add the ArrayResolver:

container.Kernel.Resolver.AddSubResolver(new ArrayResolver(container.Kernel));
