XmlNode.PrependChild Method

Adds the specified node to the beginning of the list of child nodes for this node.

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

abstract PrependChild : 
        newChild:XmlNode -> XmlNode  
override PrependChild : 
        newChild:XmlNode -> XmlNode

Parameters

newChild
Type: System.Xml.XmlNode

The node to add. All the contents of the node to be added are moved into the specified location.

Return Value

Type: System.Xml.XmlNode
The node added.

ExceptionCondition
InvalidOperationException

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.

ArgumentException

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.
