In the .NET Framework 2.0 release, the recommended practice is to create XmlReader instances using the XmlReader.Create method. This allows you to take full advantage of the new features introduced in this release. For more information, see Creating XML Readers.
Because XmlTextReader uses the System.Text.Encoding class, XmlTextReader also supports all encodings supported by that class. The exception to this is any encoding, such as UTF-7 or EBCDIC, that maps the <?xml sequence to different byte values than UTF-8.
