XmlDocument::Save Method (TextWriter)
Saves the XML document to the specified TextWriter.
Assembly: System.Xml (in System.Xml.dll)
The operation would not result in a well formed XML document (for example, no document element or duplicate XML declarations).
The encoding on the TextWriter determines the encoding that is written out (The encoding of the XmlDeclaration node is replaced by the encoding of the TextWriter). If there was no encoding specified on the TextWriter, the XmlDocument is saved without an encoding attribute.
This method is a Microsoft extension to the Document Object Model (DOM).
Note that only the Save method enforces a well-formed XML document. All other Save overloads only guarantee a well-formed fragment.
