Serialization

[Alexander]

There was such problem,

At compilation with SP1 (dotnetfx11SP1)

On computers without him{it} ÎÅÄÅÓÅÒÉÁÌÉÚÕÀÔÓÑ some objects.

For example (System. Collections. Comparer) and together with it{him} and
all objects in which it{he} is used, for example ArrayList

Whether it is possible to bypass it somehow

I'm afraid your question isn't very clear at all.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

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.SerializationExceptio n:

Right. Effectively, you've got different versions of ArrayList. I'm not
entirely surprised serialization doesn't work in this case, to be
honest. Not sure that the error message is as useful as it could be,
but I think it's generally unlikely that serialization will work
between different versions of the framework. Then again, I'm not a
serialization expert by any stretch of the imagination.

I would think that if the serialized bits are going to be persisted to disk
it would be best (safest) policy to do your own serialization. You would
also want to be sure to store a version number in the image so that later
versions can restore successfully.
