Something like this (warning - not compile tested):

// get the methodinfo for the method you want to add
MethodInfo methodToAdd = typeof(AAA).GetMethod("MyMethod");

// create a delegate instance for it
Delegate methodDelegate = Delegate.CreateDelegate(typeof(BBB.MyDelegate), methodToAdd);

// get the event you want to add to
EventInfo eventToAddMethodTo = typeof(BBB).GetEvent("MyEvent");

// call the event's add method, with the delegate you want to add
eventToAddMethodTo.AddEventHandler(null /*or the AAA instance if this is a non-static event */, methodDelegate);

If it's not an event you want to add to, but just another Delegate, then you use Delegate.Combine:

Delegate combinedDelegate = Delegate.Combine(oldDelegate, methodDelegate);
