FLASH+XML图片动态轮换效果

今天把首页那个动态图片轮换效果换成XML读取了，不从数据库中读取了，这样可以节约点SQL的资源。XML格式如下

<?xml version="1.0" encoding="utf-8"?>
<flash>
  <item0 item_url="http://www.cdccis.com/images/1182948631878_75_100.jpg" link="http://www.cdccis.com/news/2007-9-6/200796115219.htm" itemtitle="11">

读取,写入XML关键代码如下：

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Xml;

namespace Bll.Swort
{
    /// <summary>
    /// 完成FLASH中图片以及链接和标题的设置
    /// </summary>
   public class PicFlash
    {
       /// <summary>
       ///
       /// </summary>
       /// <param name="address">绝对地址</param>
        public PicFlash(string address)
        {
            xmladdress = address;
        }
        public PicFlash()
        {

        }
        private string xmladdress;
        /// <summary>
        /// 进行某一个图片的设置
        /// </summary>
        /// <param name="i">要设置的第几幅图片</param>
        /// <param name="img">图片地址</param>
        /// <param name="url">链接地址</param>
        /// <param name="title">图片标题</param>
        public void SingeSet(int picNumber, string img, string url, string title)
        {
            if (File.Exists(xmladdress))
            {
                XmlDocument xmlReader = new XmlDocument();
                xmlReader.Load(xmladdress);
                string itemNode = "item" + (picNumber-1).ToString();
                XmlNode node = xmlReader.SelectSingleNode("flash");
                for (int i = 0; i < node.ChildNodes.Count; i++)
                {

                    if (node.ChildNodes[i].Name == itemNode)
                    {
                        XmlElement element = (XmlElement)node.ChildNodes[i];
                        element.Attributes[0].Value = img;
                        element.Attributes[1].Value = url;
                        element.Attributes[2].Value = title;
                        xmlReader.Save(xmladdress);
                    }

                }

}
}

        /// <summary>
        /// 进行全部图片的设置
        /// </summary>
        public void AllSet(string[] img,string[] url,string[] title)
        {
            for (int i = 0; i < 6; i++)
            {
                SingeSet((i + 1), img[i], url[i], title[i]);

            }

        }
        /// <summary>
        /// 读取XML文档中FLASH的设置
        /// </summary>

        public void ReadPic(ref string[] img, ref string[] url, ref string[] title)
        {

           if (File.Exists(xmladdress))
           {
               XmlDocument xmlReader = new XmlDocument();
               xmlReader.Load(xmladdress);

               XmlNode node = xmlReader.SelectSingleNode("flash");
               for (int i = 0; i < node.ChildNodes.Count; i++)
               {

                       XmlElement element = (XmlElement)node.ChildNodes[i];
                     img[i]= element.Attributes[0].Value ;
                    url[i] = element.Attributes[1].Value;
                     title[i]= element.Attributes[2].Value;


               }
           }

}

前台只要把FLASH的几幅图片设置成从XML读取中的数据就可以了。
