Deserializing object

[Søren M. Olesen]

Hi

Is there any way (at all) that an object beign deserialized from a stream
can know (or figure out) that it has been created because of a deserialize
process rather than by a "normal" object instiantiation ??


TIA

Maybe u can create a property "IsDeserialized" and flag the object during
deserialization?

How about this :

<Serializable()> Class YourObject

<nonserialized()> Public HasBeenNormallyInstantiated As Boolean =
True

'Other properties ...

End Class

the flag HasBeenNormallyInstantiated will hold the answer because when
deserialized will be false. Will be true when YourObject "normally"
instantiated.

Well yes... If you implement the ISerializable interface, then you
will have to add a constructor like:

Public Sub New (ByVal info As SerializationInfo, ByVal context As
StreamingContext)

This constructor will be called when the object is deserialized.
