XDocument::Save Method (TextWriter, SaveOptions)
Assemblies: System.Xml.XDocument (in System.Xml.XDocument.dll)
System.Xml.Linq (in System.Xml.Linq.dll)
If you want to save unindented XML, specify the DisableFormatting flag for options. This will cause the writer to write all white space exactly as represented in the XML tree.
If you want to save indented XML, do not specify the DisableFormatting flag for options. This will remove all extraneous insignificant white space, and add appropriate insignificant white space so that the XML is properly indented. This is the default behavior, and the behavior of the overloads of the Save methods that do not take options as a parameter.
For more information, see Preserving White Space while Loading or Parsing XML and Preserving White Space While Serializing.
The following example shows two uses of this method. The first use serializes the XDocument with formatting. The second preserves white space. Because the document has no white space in it as constructed, preserving white space outputs the XML without any indenting.
This example produces the following output:
<?xml version="1.0" encoding="utf-16"?> <Root> <Child>content</Child> </Root> <?xml version="1.0" encoding="utf-16"?><Root><Child>content</Child></Root>
