动态往xml中添加数据

类：

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Xml;/// <summary>///Class1 的摘要说明/// </summary>public class Class1{    private XmlDocument xmlDoc;    private string author;    private string publisher;    private string date;    private string name;    private string isbn;    private string price;public Class1(){////TODO: 在此处添加构造函数逻辑//}    public Class1(string au, string pu, string date, string na, string isbn,string price)    {        this.author = au;        this.publisher = pu;        this.date = date;        this.name = na;        this.isbn = isbn;        this.price = price;    }    /// <summary>    /// 加载XML文件的方法    /// </summary>    /// <param name="xmlfile">XML文件路径</param>    private void LoadXml()    {        xmlDoc = new XmlDocument();        xmlDoc.Load(System.Web.HttpContext.Current.Server.MapPath("books.xml"));    }    public void AddNode()    {        //加载文档        LoadXml();        //选择根节点        XmlNode xmldocboot = xmlDoc.SelectSingleNode("books");        //开始添加节点及节点的属性        XmlElement ele = xmlDoc.CreateElement("book");        XmlElement ele1 = xmlDoc.CreateElement("author");        ele1.InnerText = author;        XmlElement ele2 = xmlDoc.CreateElement("publisher");        ele2.InnerText = publisher;        XmlElement ele3 = xmlDoc.CreateElement("date");        ele3.InnerText = date;        XmlElement ele4 = xmlDoc.CreateElement("name");        ele4.InnerText = name;        XmlElement ele5 = xmlDoc.CreateElement("isbn");        ele5.InnerText = isbn;        XmlElement ele6 = xmlDoc.CreateElement("price");        ele6.InnerText = price;        ele.AppendChild(ele1);        ele.AppendChild(ele2);        ele.AppendChild(ele3);        ele.AppendChild(ele4);        ele.AppendChild(ele5);        ele.AppendChild(ele6);        //将节点保存到根节点下        xmldocboot.AppendChild(ele);        //保存XML文件的修改-此处要注意        xmlDoc.Save(System.Web.HttpContext.Current.Server.MapPath("books.xml"));    }}

后台调用：

 Class1 myxml = new Class1(this .txt_author .Text ,this .txt_pub .Text ,this .txt_date .Text ,this .txt_bookname .Text ,this .txt_isbn .Text ,this .txt_price .Text );        //执行添加命令        myxml.AddNode();
