Gets or sets the XML declaration for this document.
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
Sometimes you have to create an XML declaration for a document. If you want to indicate that a document is standalone, you must use this property. If you want to encode your document with an encoding other than utf-8, you can specify an encoding through the XDeclaration. Another approach for encoding a document is to specify the encoding on an XmlWriter that you pass to LINQ to XML for writing.
The following example uses this property to retrieve the XML declaration of a document.
XDocument doc = new XDocument( new XDeclaration("1.0", "utf-8", "yes"), new XComment("This is a comment"), new XElement("Root", "content") ); Console.WriteLine(doc.Declaration);
This example produces the following output:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
