Deserialization with a removed class

[Joe]

Hello all!

I'm trying to deserialize an object which has a few members which no longer
exist. Is there anyway using a custom binder to remove the reference to
these objects or just return a null?

Thanks,
Joe

Hello Joe,

There is only 2 ways: either use try/catch or use reflection. I prefer second
one.
In that case you identify the target fields and populate these that actually
exist in the serialization stream

Joe,

You have two options here. The first is to implement ISerializable on
the class itself, and handle the case when the members don't exist to
deserialize.

The second is to implement ISerializationSurrogate on a class, and then
have that be the surrogate for the type (you have to set up the formatter to
do this though).

Hope this helps.

I'm already using a surrogate. I did find a way within the SetObjectData to
fix my problem.

Thanks,
