在Autofac中使用同一接口注册多个对象

Question

I'm calling the below code in XYZManager class's constructor and the application is working.

var handlers = new ITableType[]
{
    new AbcHandler(new Logger(), new Repository()),
    new OtherHandler(new Logger(), new Repository())
    /*etc...*/
};

XYZManager , Logger and Repository are registered in my application using Autofac.

The problem is I will have around 25 handlers when I go live and so would like very much a way to have a more maintainable code...

I hope I have been able to explain my problem.

EDIT: What I would like to know is how to register my handlers in autofac and what changes do I need to make to my above code..

I guess I could register every handler like this :

builder.RegisterType<AbcHandler>().As<ITableType>()

But how do I change my XYZManager class's constructor

Answer 1

After you register your implementors of ITableType , you can define your constructor like so...

public XYZManager(ITableType[] handlers, /* other params... */)
{

}

and Autofac will give you an array with one of each of your registered ITableType objects.
