When the System.Xml.XmlReader object is created with the current node and its child nodes, the System.Xml.XmlReader object's System.Xml.XmlReader.ReadState property is set to System.Xml.ReadState.Initial. When the System.Xml.XmlReader object's System.Xml.XmlReader.Read method is called for the first time, the System.Xml.XmlReader is moved to the current node of the System.Xml.XPath.XPathNavigator. The new System.Xml.XmlReader object continues to read until the end of the XML tree is reached. At this point, the System.Xml.XmlReader.Read method returns false and the System.Xml.XmlReader object's System.Xml.XmlReader.ReadState property is set to System.Xml.ReadState.EndOfFile.

Namespace declarations for the in-scope namespaces of the current node are not inserted into the XML stream provided to the System.Xml.XmlReader object.

This method creates the System.Xml.XmlReader object with specific reader settings, and the module that uses this method has no control over those settings. For example, the reader returned by this method prohibits processing Data Type Definitions (DTDs). If the reader attempts to read a file that uses a DTD, it will throw an error, System.Xml.XmlException. The message for the exception will be Unexpected DTD declaration.

You can change this behavior by implementing a custom System.Xml.XmlResolver that returns an System.Xml.XmlReader with the desired System.Xml.XmlReaderSettings.
