Dataset serialization

[Guest]

wonder if anyone can help me here,
i've a framework 1.1 dataset which i serialize in framework 1.1 and
deserialize in framework 2.0.

This is fine, problem is that i want to modify some of the records in
framework 2.0 and serialize the data so framework 1.1 can deserialize it and
do what it required.

Is this possible?

I know for DateTime that I can work around serialization problems with the
SpecifyKind command, is there anything I can do?

thanks for any help

Hi,

AFAIK you can do it, have you tried it?

Dataset serialize in a XML file, so I bet it will be interpreted correctly
in 1.1

cheers,

Hi Ignacio,

Yes I've tried it with a very simple dataset, one table with one column, i
create one recored.

2.0 can interperate the 1.1 xml serialized file, not the other way around.
And this is with xml, binary gets even worse (or better depending on view
point)
2.0 binary serialization has been greatly improved in that it's no longer
binary serialized xml.


Basically i was wondering was there an property something like
SerializeAsFramework_1.1 which there isn't.

as a comparison consider Winword, you can save you office 2003 winword
document as a word97 file, it's this type of stuff i required.

Anyways not to worry, i'll just have to create my own data object and use
this for serialization until bother ends of my solution are framework 2.0.


Thanks for you help all the same.

Regards
Brian

Hi,

What is the differences you see in both xml files ?

I haven't read nothing like that, but it worries me now as I'm planning to
have a similar escenario sometimes soon.

Hi again,

There are quite a few changes, by looking at the xml generated from a simple
one column one record table serialized to a file. see end of post.
Datasets have version breaking changes namely (DataSet.GetObjectData,
DataTable.GetObjectData), the serialization is just different so there ain't
no way around it that i can think of, unless you create ur own serialization
but this is even more hassle.

I've just created a Datastructure with the information i need and put a
"TODO: Remove all this nonsence when server moves to famework 2.x") in my
code.

Bit of a pity really but sure i've only a few month to wait for 2.0.

here are the two files if you're interested.
