XDocument.Load Method (XmlReader)


Creates a new XDocument from an XmlReader.

Namespace:   System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

public static XDocument Load(
	XmlReader reader


Type: System.Xml.XmlReader

A XmlReader that contains the content for the XDocument.

Return Value

Type: System.Xml.Linq.XDocument

An XDocument that contains the contents of the specified XmlReader.

One possible use for this method is to create a copy of a DOM document in a LINQ to XML tree. To do this, you create an XmlNodeReader from a DOM document, and then use the XmlNodeReader to create an XDocument.

LINQ to XML's loading functionality is built upon XmlReader. Therefore, you might catch any exceptions that are thrown by the XmlReader.Create overload methods and the XmlReader methods that read and parse the document.

The following example creates a DOM document, creates an XmlNodeReader from the DOM document, creates an XDocument using the XmlNodeReader.

                // Create a DOM document with some content.
XmlDocument doc = new XmlDocument();
XmlElement child = doc.CreateElement("Child");
child.InnerText = "child contents";
XmlElement root = doc.CreateElement("Root");

// create a reader and move to the content
using (XmlNodeReader nodeReader = new XmlNodeReader(doc)) {
    // the reader must be in the Interactive state in order to
    // create a LINQ to XML tree from it.

    XDocument xRoot = XDocument.Load(nodeReader);

This example produces the following output:

  <Child>child contents</Child>
