　　代碼如下  using System;
using SystemCollectionsGeneric;
using SystemComponentModel;
using SystemData;
using SystemDrawing;
using SystemText;
using SystemWindowsForms;
using SystemXml;
namespace XMLDOMDemo

　　public partial class Form : Form

public Form()
{
InitializeComponent();
}
private void btnLoad_Click(object sender EventArgs e)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDocLoad(Booksxml);
MessageBoxShow(xmlDocInnerXml);
}
//創建文檔
private void btnCreate_Click(object sender EventArgs e)
{
XmlDocument xmlDoc = new XmlDocument();
//建立Xml的定義聲明
XmlDeclaration dec = xmlDocCreateXmlDeclaration( GB null);
xmlDocAppendChild(dec);
//創建根節點
XmlElement root = xmlDocCreateElement(Books);
xmlDocAppendChild(root);
XmlNode book = xmlDocCreateElement(Book);
XmlElement title = xmlDocCreateElement(Title);
titleInnerText = SQL Server;
bookAppendChild(title);
XmlElement isbn = xmlDocCreateElement(ISBN);
isbnInnerText = ;
bookAppendChild(isbn);
XmlElement author = xmlDocCreateElement(Author);
authorInnerText = jia;
bookAppendChild(author);
XmlElement price = xmlDocCreateElement(Price);
priceInnerText = ;
priceSetAttribute(Unit ___FCKpd___quot;);
bookAppendChild(price);
rootAppendChild(book);
xmlDocSave(Booksxml);
}

　　private void btnInsert_Click(object sender EventArgs e)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDocLoad(Booksxml);
XmlNode root = xmlDocSelectSingleNode(Books);
XmlElement book = xmlDocCreateElement(Book);

MessageBoxShow(數據已寫入！);
}

　　private void btnUpdate_Click(object sender EventArgs e)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDocLoad(Booksxml);
////Book[@Unit=\$\]
//獲取Books節點的所有子節點
XmlNodeList nodeList = xmlDocSelectSingleNode(Books//Book)ChildNodes;
