autofac多个服务（相同的界面-提供它的多个插件）如何实现？

Question

I have a service interface, lets say IAddonServiceX which is implemented by many, but not all addons to a system. I want to have an IEnumerable so that I could iterate and execute methods for every addon that registered this service? Ho can this be done with autofac?

Answer 1

Autofac has implicit support for it , so you just need register your implementations with

builder.RegisterType<Impl1>.As<IAddonServiceX>();    
builder.RegisterType<Impl2>.As<IAddonServiceX>();

And when you are resolving an IEnumberable<IAddonServiceX> with container.Resolve<IEnumberable<IAddonServiceX>> or using IEnumberable<IAddonServiceX> in your constructor then Autofac will provide you all the implementations.
