Importing and Exporting to XML
Spread WinRT Documentation > Developer's Guide > Managing Data > Importing and Exporting to XML

You can save data and formatting to an XML file or just data. Data and formatting are imported when loading from an XML file.

You can use the OpenXmlAsnyc method to load data in code and the SaveXmlAsync method to save data.

Using Code

This example opens and saves to XML.
