Xml Text Writer

XmlTextWriter Represents a writer that provides a fast, non-cached, forward-only way of generating streams or files containing XML data. XmlTextWriter renders XML data to a string. This string remains in the memory of the C# program. XmlTextWriter is useful for in-memory generation of XML.
