The XML data in a dataset can be accessed by calling the available XML methods on the dataset. To save the data in XML format, you can call either the GetXml method or the WriteXml method of a DataSet.
Calling the GetXml method returns a string that contains the data from all data tables in the dataset that's formatted as XML.
Calling the WriteXml method sends the XML-formatted data to a file that you specify.
