调用Autofac中的所有ISomething实例 [英] Calling all ISomething instances in Autofac

问题描述

我有一个接口ISomething，带有启动方法. 我想获取此接口的所有实现(在多个程序集中，在主要程序集和所有引用的程序集中)，并在应用程序启动时调用Start方法. 如何使用Autofac 2.4.4.705做到这一点?

I have an interface ISomething with a method Start. I want to get all implementations of this interface (in multiple assemblies, the main one and all referenced ones) and call the Start method on application start. How can I do this with Autofac 2.4.4.705?

推荐答案

您可以解决

 IEnumerable<ISomething>

并为每个电话呼叫开始"

and call Start for each of them

忘记了，您应该首先注册ISomething的所有实现.

Forgot to mention, that you should first register all implementations of ISomething.

Assembly[] assemblies = ...;
var builder = new ContainerBuilder();
builder.RegisterAssemblyTypes(assemblies).AssignableTo<ISomething>().As<ISomething>();
var container = builder.Build();

程序集"是您要从中注册的程序集数组.

Where "assemblies" is an array of assemblies you want to register from.
