class Program
{
static void Main()
{
var styleInstruction = new XProcessingInstruction("xml-stylesheet", "href='styles.css' type='text/css'");
var docType = new XDocumentType("html", "-//W3C//DTD XHTML 1.0 Strict//EN", "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd", null);
XNamespace ns = "http://www.w3.org/1999/xhtml";
var root = new XElement(ns + "html", new XElement(ns + "head",
new XElement(ns + "title", "An XHTML page")), new XElement(ns + "body",
new XElement(ns + "p", "This is the content"))
);
var doc = new XDocument(
new XDeclaration("1.0", "utf-8", "no"), new XComment("Reference a stylesheet"), styleInstruction,
docType, root);
doc.Save("test.html");
Console.WriteLine(doc.Root.Name.LocalName); // html
XElement bodyNode = doc.Root.Element(ns + "body");
Console.WriteLine(bodyNode.Document == doc); // True
}
}
The output:
html
True
XDeclaration's constructor accepts three arguments, which correspond to the attributes version, encoding, and standalone.
In the following example, test.xml is encoded in UTF-16:

using System.Xml.Linq;
class Program
{
static void Main()
{
var doc = new XDocument(
new XDeclaration("1.0", "utf-16", "yes"),
new XElement("test", "data")
);
doc.Save("test.xml");
Console.WriteLine(doc);
}
}
The output:
