Serialization between different versions of the framework

[Alexander]

When i store rule on PC with .NET.SP1 i cant restore them from PC without
SP1.
An i get this Error:

System.Runtime. Serialization.S erializationExc eption:
Possible Version mismatch. Type System.Collecti ons.Comparer has 1 members,
number of members deserialized is 0.

Alexander,

This isn't necessarily related to different versions of the framework as
much as it is related to differences between the class type you are trying
to deserialize into. The metadata definition has changed, and isn't in sync
with what was found in the stream you are trying to deserialize from. Since
this is a framework type, you have little choice but to use serialized
versions of that type.

However, if it was your own type, you could implement custom
serialization, and perform a check to see what is available in the
SerializationIn fo class. If the values you need are not there, then you can
set to default values.

The serialization model in .NET 2.0 will include an OptionalField
attribute which when set on a field, will not cause an error if the
information does not exist in the serialized stream. This is to stem errors
from versioning, of course.

Hope this helps.

Yes, but error in "System.Collect ions.Comparer" wich contains in
ArrayList(Condi tions and Actions inherit it), how can i control
serialization of ArrayList?

Alexander,

That's the thing, you can not. If you need to control this, you might
have to use a different class (Comparer is an implementation of IComparer,
right? Use a different implementation that you control) altogether.
