XmlNode.AppendChild(XmlNode) XmlNode.AppendChild(XmlNode) XmlNode.AppendChild(XmlNode) XmlNode.AppendChild(XmlNode) Method


將指定的節點加入這個節點之子節點清單的結尾。Adds the specified node to the end of the list of child nodes, of this node.

 virtual System::Xml::XmlNode ^ AppendChild(System::Xml::XmlNode ^ newChild);
public virtual System.Xml.XmlNode AppendChild (System.Xml.XmlNode newChild);
abstract member AppendChild : System.Xml.XmlNode -> System.Xml.XmlNode
override this.AppendChild : System.Xml.XmlNode -> System.Xml.XmlNode
Public Overridable Function AppendChild (newChild As XmlNode) As XmlNode


XmlNode XmlNode XmlNode XmlNode

要加入的節點。The node to add. 要加入之節點的所有內容會移入指定的位置。All the contents of the node to be added are moved into the specified location.


已加入的節點。The node added.


這個節點的型別不允許 newChild 節點型別的子節點。This node is of a type that does not allow child nodes of the type of the newChild node.

newChild 是這個節點的上階。The newChild is an ancestor of this node.

newChild 由不同於建立這個節點的另一份文件所建立。The newChild was created from a different document than the one that created this node.

這個節點是唯讀的。This node is read-only.


下列範例會將新的節點加入至 XML 檔。The following example adds a new node to the XML document.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' ISBN='1-861001-57-5'>"
   "<title>Pride And Prejudice</title>"
   "</book>" );
   XmlNode^ root = doc->DocumentElement;
   //Create a new node.
   XmlElement^ elem = doc->CreateElement( "price" );
   elem->InnerText = "19.95";
   //Add the node to the document.
   root->AppendChild( elem );
   Console::WriteLine( "Display the modified XML..." );
   doc->Save( Console::Out );

using System;
using System.IO;
using System.Xml;

public class Sample {

  public static void Main() {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +

    XmlNode root = doc.DocumentElement;

    //Create a new node.
    XmlElement elem = doc.CreateElement("price");

    //Add the node to the document.

    Console.WriteLine("Display the modified XML...");

Public Class Sample
    Public Shared Sub Main()
        Dim doc As New XmlDocument()
        doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" & _
                    "<title>Pride And Prejudice</title>" & _
        Dim root As XmlNode = doc.DocumentElement
        'Create a new node.
        Dim elem As XmlElement = doc.CreateElement("price")
        elem.InnerText = "19.95"
        'Add the node to the document.
        Console.WriteLine("Display the modified XML...")
    End Sub
End Class


Display the modified XML...  
<?xml version="1.0" encoding="IBM437"?>  
<book genre="novel" ISBN="1-861001-57-5">  
  <title>Pride And Prejudice</title>  


如果 newChild 已經在樹狀結構中,就會從其原始位置中移除,並將其新增至目標位置。If the newChild is already in the tree, it is removed from its original position and added to its target position. 如需插入節點的詳細資訊,請參閱將節點插入 XML 檔For more information about inserting nodes, see Inserting Nodes into an XML Document.

如果要插入的節點是從另一個檔建立的,您可以使用 XmlDocument.ImportNode,將節點匯入到目前的檔。If the node being inserted was created from another document, you can use XmlDocument.ImportNode to import the node to the current document. 然後,匯入的節點可以插入目前檔中。The imported node can then be inserted into the current document.


在衍生類別中覆寫 AppendChild 時,為了讓事件正確引發,您必須呼叫基類的 AppendChild 方法。When overriding AppendChild in a derived class, in order for events to be raised correctly, you must call the AppendChild method of the base class.
