passing a dataset through a webservice

Hi,
I'm a really a newby in .NET webservices technologies. I've just started in.

I want to pass a typed dataset from my client app to the webserver application.
To start, I created a webmethod and passed a dataset parameter to it. For instance:

<WebMethod>
Public Function PassDataSet(ByVal orderDataSet As OrderDataSet) As Integer
_orderDataSet = orderDataSet
Return 0
End Function

_orderDataSet is an attribute of the webservice class. The problem I have is that my _orderDataSet is not stored as persistent, so It becomes empty when I try to call it from an other method.

I don't have any idea about how to perform that. I heard about XML serialization, but I don't know how to apply it in this simple practical case.

Excuse my language style. English is not my mother tongue.

Thanks

    Hi,
    Web Service application, as any other web application is stateless by default.
    In order to achieve stateful logic you will have to store _orderDataSet in Session or as a static attibute of the Global.asax class (in case static is ok for you)

    Hope it helps,
