Using the save method to a XmlWriter http://msdn.microsoft.com/en-us/library/bb336977.aspx, and creating this XmlWiter with XmlWriterSettings http://msdn.microsoft.com/en-us/library/system.xml.xmlwriter.settings.aspx

XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;


XmlWriter writer = XmlWriter.Create(yourstream, settings);

yourXDocument.Save(writer);
