Examples

The following example uses this property to get the root element of a document.

Dim output As New StringBuilder
Dim doc As XDocument = _
    <?xml version="1.0" encoding="utf-8" standalone="yes"?>
    <!--This is a comment.-->
    <Pubs>
        <Book>
            <Title>Artifacts of Roman Civilization</Title>
            <Author>Moreno, Jordao</Author>
        </Book>
        <Book>
            <Title>Midieval Tools and Implements</Title>
            <Author>Gazit, Inbar</Author>
        </Book>
        <!--This is another comment.-->
    </Pubs>

output.Append(doc.Root.Name.ToString())
output.Append(Environment.NewLine)


OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
XDocument doc = new XDocument(
    new XComment("This is a comment."),
    new XElement("Pubs",
        new XElement("Book",
            new XElement("Title", "Artifacts of Roman Civilization"),
            new XElement("Author", "Moreno, Jordao")
        ),
        new XElement("Book",
            new XElement("Title", "Midieval Tools and Implements"),
            new XElement("Author", "Gazit, Inbar")
        )
    ),
    new XComment("This is another comment.")
);
output.Append(doc.Root.Name.ToString() + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
