如何从dll文件订阅事件并获取dll生成的列表？

Question

So I have a dll file that generates people and data about them. Every time something changes the dll raises an event. I need to subscribe to the event and then process the data.

I have the following information about the dll

namespace PeopleGenerator 
{ 
    public class RawPeopleDataEventArgs : EventArgs 
    {
        public RawPeopleDataEventArgs(List<string> peopleData) 
        {
            PeopleData = peopleData; 
        }
        public List<string> PeopleData { get; } 
    }
    public interface IPeopleGenerator 
    {
        event EventHandler<RawPeopleDataEventArgs>  PeopleDataReady; 
    }
} 

I have also been given info about a factory I can use to get an IPeopleGenerator object

namespace PeopleGenerator 
{ 
    public class PeopleGeneratorFactory 
    {
        public static IPeopleGenerator CreatePeopleDataReceiver() 
    }
}

Now I have tried to make a subscription class

namespace Test
{
    class EventSubscriber
    {       
        public EventSubscriber(object o, RawPeopleDataEventArgs args)
        {
            List<string> listofpeople = args.PeopleData;
            printList(listofpeople);
        }

        void printList(List<string> print)
        {
            print.ForEach(Console.WriteLine);
            // More data processing to happen here
        }
    }
}

My problem is I cant't figure out how to start generating the data from the dll. with the factory class. My thought is something like this

static void Main(string[] args)
{
    //generate a new object
    EventSubscriber sub = new EventSubscriber(????);
    Console.WriteLine("Press any key to exit.");
    Console.ReadKey();
}

You subscribe methods, not classes, modify your subscriber as following:

 namespace Test
    {
        class EventSubscriber
        {       
            public HandlePeople(object o, RawPeopleDataEventArgs args)
            {
                List<string> listofpeople = args.PeopleData;
                printList(listofpeople);
            }

            void printList(List<string> print)
            {
                print.ForEach(Console.WriteLine);
                // More data processing to happen here
            }
        }
    }  

And use instance of subscriber (and its method) to handle events:

static void Main(string[] args)
    {
        var recvr = PeopleGenerator.PeopleGeneratorFactory.CreatePeopleDataReceiver();
        var subscriber = new EventSubscriber();
        recvr.PeopleDataReady += new subscriber.Handle;

        Console.WriteLine("Press any key to exit.");
        Console.ReadKey();
    }
