What is the best practise for passing objects from and to webservices?

[Ilyas]

Hi all

What are the best practises for passing custom objects to and from
from services? In particular:

1)Should datasets be passed, or custom objects be passed?
2)When it comes to passing collections of objects what options are
there? Should datasets be used here or should a generic list
collection be used instead?

Many thanks

Re: What is the best practise for passing objects from and to web services?

The answer to both really depends on a lot of things. I would say though
that from my observation, the consensus is to shun using datasets in web
services. One of the main reasons is interoperabilit y - you'll either have
to modify the xml in the dataset so that it's easily consumed or live with
the fact that non-dotnet clients are going to have some problems.

Here are a few thoughts you'll find useful

The answer to the second one is very similar to the first one - at least the
implication are the same.
