XDocument Constructor

Initializes a new instance of the XDocument class.

Namespace:  System.Xml.Linq
Assemblies:   System.Xml.XDocument (in System.Xml.XDocument.dll)
  System.Xml.Linq (in System.Xml.Linq.dll)

public XDocument()

There are not many scenarios that require you to create an XDocument. Instead, you can usually create your XML trees with an XElement root node. Unless you have a specific requirement to create a document (for example, because you have to create processing instructions and comments at the top level, or you have to support document types), it is often more convenient to use XElement as your root node.

For details about the valid content of an XDocument, see Valid Content of XElement and XDocument Objects.

The following example creates a new document, and then adds a comment and an element to it.

XDocument doc = new XDocument();
doc.Add(new XComment("This is a comment"));
doc.Add(new XElement("Root", "content"));
Console.WriteLine(doc);

This example produces the following output:

<!--This is a comment-->
<Root>content</Root>
