Web Service: DataSet or Stream.Best Practice.

[IM]

Hi,

I need to transfer a DataSet object from WebClient to WebService. Is there a
difference between transmitting a DataSet object and a Stream object? Also,
what is the best practice in this case?
Dim Ds1 As System.Data.DataSet
Dim oStream As System.IO.Stream

WebService1.MethodName(Ds1)

Or

Ds1.WriteXml(oStream)
WebService1.MethodName(oStream)

Thanks,

IM
