Assistance with Generics

[jmeckley]

This is escaping me, and I don't work with metadata enough to connect the dots. here is the setup

interface IListener<T>
{
  void Handle(T message);
}

class Presenter 
   : BaseClass
   , IAnotherInterface
   , IListener<This>
   , IListener<That>
{
   public void Handle(This message)
   {
   }
   public void Handle(That message)
   {
   }
}

based on the type, how can I tell it implements IListener? It doesn't matter what the closed type is, only that it's implemented. for example:

var listener = typeof(IListener<>);
var presenter = typeof(Presenter);

var implementsListener = presenter
   .GetInterfaces()
   .Any(interface => interface ???? listener);

//implementsListener is True

thank in advance.

some trial and error and i figured it out.

var isAListener = typeof(Presenter)
   .GetInterfaces()
   .Where(i => i.IsGenericType)
   .Select(i => i.GetGenericTypeDefinition())
   .Any(i => i == listener);
