   writer->WriteStartElement( "p" );
   
   // Write the xml:space attribute.
   writer->WriteAttributeString( "xml", "space", nullptr, "preserve" );
   
   // Verify that xml:space is set properly.
   if ( writer->XmlSpace == XmlSpace::Preserve )
      Console::WriteLine( "xmlspace is correct!" );

   
   // Write out the HTML elements.  Insert white space
   // between 'something' and 'Big'
   writer->WriteString( "something" );
   writer->WriteWhitespace( "  " );
   writer->WriteElementString( "b", "B" );

Comentarios

Nota:

A partir de .NET Framework 2.0, se recomienda crear XmlWriter instancias mediante el XmlWriter.Create método y la XmlWriterSettings clase para aprovechar las nuevas funcionalidades.

Este método se usa para dar formato manual al documento. Utilice la Formatting propiedad para que el escritor dé formato a la salida automáticamente.
