Question

1) I do a Dataset.WriteToXml(memory stream object) 2) Then i create a XMLDocument object 3) I then XMLDocument.Load (memory stream object)

I get a ‘XML Root namespace not found’ exception.

Does the Dataset XML not include the required namespace ?

Thanks.

Are you repositioning your memory stream before trying to load it into the XmlDocument?

DataSet ds = new DataSet(); using (SqlConnection connection = new SqlConnection('some connection string')) using (SqlCommand command = new SqlCommand('select * from mytable', connection)) using (SqlDataAdapter adapter = new SqlDataAdapter(command)) {     adapter.Fill(ds); }  XmlDocument xml = new XmlDocument(); using (Stream stream = new MemoryStream()) {     ds.WriteXml(stream);     // We must reposition the memory stream before loading the xml     stream.Position = 0;     xml.Load(stream); }
