In the .NET Framework version 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 does a buffered Read, it must be able to return the remainder of the unused buffer so that no data is lost. This allows protocols (such as multi-part MIME) to package XML in the same stream as other things.
After calling this method, EOF is set to true.
The following example reads the first part of an XML document and then uses GetRemainder to complete reading the document using a second reader.
