I have a data object that is deep-cloned using a binary serialization. This data object supports property changed events, for example, PriceChanged.

Let's say I attached a handler to PriceChanged. When the code attempts to serialize PriceChanged, it throws an exception that the handler isn't marked as serializable.

My alternatives:

• I can't easily remove all handlers from the event before serialization
• I don't want to mark the handler as serializable because I'd have to recursively mark all the handlers dependencies as well.
• I don't want to mark PriceChanged as NonSerialized - there are tens of events like this that could potentially have handlers.
• Ideally, I'd like .NET to just stop going down the object graph at that point and make that a 'leaf'. So why can't I just mark the handler class as 'NonSerialized'?

I finally worked around this problem by making the handler implement ISerializable and doing nothing in the serialize constructor/ GetDataObject method. But, the handler still is serialized, just with all its dependencies set to null - so I had to account for that as well.

Is there a better way to prevent serialization of an entire class?
