Answer / kirti
Both XmlReader and XmlWriter are abstract base classes, which define the functionality that all derived classes must support.
There are three concrete implementations of XmlReader:
1.XmlTextReader
2.XmlNodeReader
3.XmlValidatingReader
There are two concrete implementations of XmlWriter:
1.XmlTextWriter
2.XmlNodeWriter
XmlTextReader and XmlTextWriter support reading data to/from text-based stream, while XmlNodeReader and XmlNodeWriter are designed for working with in-memory DOM tree structure. The custom readers and writers can also be developed to extend the built-in functionality of XmlReader and XmlWriter.
