Dataset.WriteXML and Thread.CurrentThread.CurrentCulture

Hi

I am trying to write data back to the client using dataset.WriteXML and I
have set the Thread.CurrentThread.CurrentCulture to "no" (norwegian) just
before writing the data using WriteXML.
But dataset.WriteXML dosent seems to be using the CurrentCulture settings
and still writes dates, numeric values using the original settings.

My Code...

'Get the standard request/response objects from the current request
context
objHTTPRequest = context.Request
objHTTPResponse = context.Response
'Set the Thread-culture
Try
If objHTTPRequest.UserLanguages.Length > 0 Then
Thread.CurrentThread.CurrentCulture =
CultureInfo.CreateSpecificCulture(objHTTPRequest.U serLanguages(0))
End If
Catch ex As Exception
'Do nothing if CreateSpecificCulture fails
End Try

'Get the dataset
BuildDataSet(dsDataSet, objSQLParameters, strSPName, strConn,
intParameterCount)

'Start writing back the response as an XML
With objHTTPResponse
.ContentType = "text/xml"
dsDataSet.WriteXml(.OutputStream)
End With

Please advice.

Thanks
