Remarks

Note

In the .NET Framework 2.0, the recommended practice is to create XmlReader instances using the XmlReaderSettings class and the Create method. This allows you to take full advantage of all the new features introduced in the .NET Framework. For more information, see the Remarks section in the XmlReader reference page.

If the current node is not an attribute node, this method is equivalent to MoveToFirstAttribute. If MoveToNextAttribute returns true, the reader moves to the next attribute; otherwise, the position of the reader does not change.
