Calling all ISomething instances in Autofac

问题

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?

回答1:

you can resolve

 IEnumerable<ISomething>

and call Start for each of them

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();

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