Name
XmlDataDocument
Synopsis
The XmlDataDocument
is a marriage of XML and RDBMS
technology; it is an XmlDocument
-inheriting class that particularly
understands ADO.NET DataSet objects. This offers a variety of opportunities
to the C# programmer—for example, a DataSet
can be
loaded into the XmlDataDocument
, and then navigated
using traditional DOM-style navigation using the XmlNode
API. In fact, because XmlDataDocument
also inherits the System.Xml.XPath.IXPathNavigable
interface, XPath
queries can be issued against the DataSet
data, as well.
In order to build this relationship, construct the XmlDataDocument
with the DataSet
holding the data as its constructor parameter. Alternatively, use the Load()
method to read in the data via an XmlReader
. The resulting XML can also then be written
out to another medium with the WriteTo()
method.
