XDocument doc = new XDocument(
new XDeclaration("1.0", "utf-8", "yes"),
new XComment("This is a comment"),
new XElement("Root", "content")
);
doc.Save("Root.xml");
Console.WriteLine(File.ReadAllText("Root.xml"));
Dim doc As XDocument = _
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<!--This is a comment-->
<Root>content</Root>
doc.Save("Root.xml")
Console.WriteLine(File.ReadAllText("Root.xml"))
