Reacting on serialize and deserialize of an instance

I have a class which i am serializing. I annotated it with [Serializable] and i am using binary serializer. Everything works fine.

But later i introduced new properties, which cannot be serialized (lets say they contain a lot of mess about GUI which does not need to be rembered). I can compute these properties based on other properties of class.

I need to do it two times, when I serialize - clean mess and enter stabile state ready for serialization. And deserialization - again compute all needed properties.

I need to react on 'events' instance is being serialized/deserialized.

However I can't find these events because I am not implementing the interface ISerializable or abstract class Aserializable but only class atribute [Serializable].

I do not know when class is being serialized because it is not the concern of this class; it is serialized as a field of another class.

Is there a way I can react on those events?

Have you considered per chance the [XmlIgnoreAttribute] attribute? It will prevent a property to be serialized. No need to tamper withe the serialization workflow.

My bad, didn't realize you wanted to reload some property on deserialization. So why not serialize these? In an optional subObject, or whatever?

Build Custome Serialization by Implementing ISerializable. Use OnSerializingAttribute, to manipulate object before serilazation and OnDeserializingAttribute, to manipulate before deserialization.

You can use OnDeserializedAttribute and its related attributes (OnSerializing, OnSerialized, OnDeserializing) to create special methods that are called during the serialization/deserialization process.
