Public Property Declaration As XDeclaration

Property Value

Type: System.Xml.Linq.XDeclaration

An XDeclaration that contains the XML declaration for this document.

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.


                Dim doc As XDocument = _
    <?xml version="1.0" encoding="utf-8" standalone="yes"?>
        <!--This is a comment-->
        <Root>content</Root>

Console.WriteLine(doc.Declaration)

This example produces the following output:


<?xml version="1.0" encoding="utf-8" standalone="yes"?>
