For more information about the valid content that can be passed to this constructor, see Valid Content of XElement and XDocument Objects in the .NET Framework documentation.

There is an implicit conversion from string to XName. Typical use of this constructor is to specify a string as the parameter instead of creating a new XName.

When creating an element in a namespace, typical use is to use the addition operator overload with an XNamespace and a string to create an XName. For more information, see Working With Namespaces in the .NET Framework documentation.

The following example creates an XML tree. The content of the new element comes from a LINQ query.


StringBuilder output = new StringBuilder();
XElement xmlTree1 = new XElement("Root",
    new XElement("Child", 1),
    new XElement("Child", 2),
    new XElement("Child", 3),
    new XElement("Child", 4),
    new XElement("Child", 5),
    new XElement("Child", 6)
);

XElement xmlTree2 = new XElement("Root",
    from el in xmlTree1.Elements()
    where ((int)el >= 3 && (int)el <= 5)
    select el
);
output.Append(xmlTree2);

OutputTextBlock.Text = output.ToString();
