The MemoryStream object provides a way to create a stream without having to do Io, XmlTextWriter and XmlReader provide a way to write and read XML content quickly, combining MemoryStream, XmlTextWriter can be constructed directly in memory and read with XmlReader.
To write XML using MemoryStream and XmlTextWriter, you need to be aware of two points: Xmltextwriter.flush operation and resetting memorystream.position = 0.
