Use the WriteXmlSchema method to write the schema for a DataTable to an XML document. The schema includes table, relation, and constraint definitions.
The XML schema is written using the XSD standard.
To write the data to an XML document, use the WriteXml method.
Normally the WriteXml method writes the data only for the current table. To write the data for the current table and all of its descendant, related tables, call the method with the writeHierarchy parameter set to true.
