XElement.Save Method (TextWriter)
Serialize this element to a TextWriter.
Assemblies: System.Xml.Linq (in System.Xml.Linq.dll)
System.Xml.XDocument (in System.Xml.XDocument.dll)
The serialized XML will be indented. All insignificant white space will be removed, and additional white space will be added so that the XML will be properly indented. The behavior of this method is that white space will not be preserved.
If you want to control white space, use the overload of Save that allows you to specify SaveOptions as a parameter. For more information, see Preserving White Space while Loading or Parsing XML and Preserving White Space While Serializing.
