Adds the specified node to the beginning of the list of child nodes for this node.
Assembly: System.Xml (in System.Xml.dll)
This node is of a type that does not allow child nodes of the type of the newChild node.
The newChild is an ancestor of this node.
The newChild was created from a different document than the one that created this node.
This node is read-only.
If the newChild is already in the tree, it is removed from its original position and added to its target position. For more information about inserting nodes, see Inserting Nodes into an XML Document.
If the node being inserted was created from another document, you can use XmlDocument.ImportNode to import the node to the current document. The imported node can then be inserted into the current document.
This method is a Microsoft extension to the Document Object Model (DOM).Notes to Inheritors
When overriding PrependChild in a derived class, in order for events to be raised correctly, you must call the PrependChild method of the base class.
The following example adds a new node to the XML document.

Dim elem As XmlElement = doc.CreateElement("price") elem.InnerText = "19.95" 'Add the node to the document. root.PrependChild(elem) Console.WriteLine("Display the modified XML...") doc.Save(Console.Out) End Sub 'Main End Class 'Sample
