Serialization of Object Graph (Inheriting ArrayList)

Hi to All, I am new to this newsgroup, so please bare with me.
Here is the deal:
        I have the following Object Graph:
    Icell (Interface)
    Iline (Interface)
    Itable (Interface)

    Classes:         Cell: implements Icell
            Line: inherits Arraylist
                Implements Iline
            Table: inherits Arraylist
                Implements Itable
And I want to serialize Class Table to a file. Cell will contain Object
types (Date, String, Decimal). Line will just implement the property
Item to find a given Cell in the ArrayList. And Table will enable the
methods Add, Remove, RemoveAt, Clear, TrimToSize & the property Count.

My question is: Should I do the following to serialize
<Serializable()> Class Cell ....
<Serializable()> Class Line ....
Class Table Implements Iserializable, IdeserializationCallback ....

OR

<Serializable()> Class Cell ....
Class Line Implements Iserializable, IdeserializationCallback ....
Class Table Implements Iserializable, IdeserializationCallback ....

OR something else ?

Please Help!!

Thank you.

Lucile.

hmm. I don't know about 2005, but in 2003, I gave up and made my own
serialization mechanism by defining an interface having

Save
Load
Version

methods

Each class serialized/deserialized in these methods and used the stored
version to limit new features on loading so that it could still load
previously saved things with older versions.

The built in stuff just seemed too much of a head ache. There is plenty to
read about with it. Jeffery Richter wrote three good papers on it. I just
came away with the impression that it was great to serialize over the
network and for things you will immediately deserialize, but very hokey
otherwise.

Good luck,

Shane
