Asking

Is Serializer a good way to write data to XML ?

Data from a dataset? There's a WriteToXML() method or something similar.

Serializer's are good and fast way of writing Xml.
It definitely has a performance advantage to it's side.

i used WriteToXML() to convert a dataset to xml and it was FAST.

Depends on your needs. If format isnt all that important, Serializing is perfect. If you want control over the format of the xml, then the XML classes are the way to go.

Actually I want to use Serializer but I am now currently working under Compact Framework so I do not know which one to use right now...

Any ideas
