本文实例讲述了asp.net类序列化生成xml文件的方法。分享给大家供大家参考,具体如下:

根据设计的需求需要开发多个商品的API 原XML文件如下:

<urlset>
 <url>
  <loc>http://www.xxxxx.com/todaydetials.aspx"htmlcode">
#region 定义数据实体类xml数据结构
public class urlset
{
  public List<url> urlList
  {
   get;
   set;
  }
}
public class url
{
  public string loc
  {
   get;
   set;
  }
  public List<data> dataList
  {
   get;
   set;
  }
}
public class data
{
  public List<display> displayList
  {
   get;
   set;
  }
}
public class display
{
  public string website
  {
   get;
   set;
  }
  public string siteurl
  {
   get;
   set;
  }
  public string city
  {
   get;
   set;
  }
  public string webSitetitle
  {
   get;
   set;
  }
  public string image
  {
   get;
   set;
  }
  public string startTime
  {
   get;
   set;
  }
  public string endTime
  {
   get;
   set;
  }
  public double value
  {
   get;
   set;
  }
  public double price
  {
   get;
   set;
  }
  public double rebate
  {
   get;
   set;
  }
  public int bought
  {
   get;
   set;
  }
}
#endregion

第二步:#region 定义获取网站信息实体类

public class WebSiteInfo
{
  /// <summary>
  /// 商品标题
  /// </summary>
  public string title { get; set; }
  /// <summary>
  /// 商品发布时间
  /// </summary>
  public DateTime createtime { get; set; }
  /// <summary>
  /// 商品图片
  /// </summary>
  public string productimg { get; set; }
  /// <summary>
  /// 市场价
  /// </summary>
  public decimal market_price { get; set; }
  /// <summary>
  /// 团购价
  /// </summary>
  public decimal team_price { get; set; }
  /// <summary>
  /// 折扣价
  /// </summary>
  public decimal zhekou_price { get; set; }
  /// <summary>
  /// 城市名称 
  /// </summary>
  public string cityName { get; set; }
  /// <summary>
  /// 商品开始时间
  /// </summary>
  public DateTime begin_time { get; set; }
  /// <summary>
  /// 结束时间
  /// </summary>
  public DateTime end_time { get; set; }
  /// <summary>
  /// 商家名称
  /// </summary>
  public string merchants_id { get; set; }
  /// <summary>
  /// 本单详情
  /// </summary>
  public string description { get; set; }
  /// <summary>
  /// 最低购买人数
  /// </summary>
  public int lowBuNo { get; set; }
  /// <summary>
  /// 商家地址
  /// </summary>
  public string Address { get; set; }
  /// <summary>
  /// 商家电话
  /// </summary>
  public string Telphone { get; set; }
  /// <summary>
  /// 城市区号
  /// </summary>
  public string cCode { get; set; }
  /// <summary>
  /// 文件夹名称
  /// </summary>
  public string folderName { get; set; }
  /// <summary>
  /// 团购状态 
  /// </summary>
  public string StatusMessage { get; set; }
  /// <summary>
  /// 现在购买人数
  /// </summary>
  public int nownumber { get; set; }
  /// <summary>
  /// 商品编号
  /// </summary>
  public int productID { get; set; }
}
#endregion

第三步:获取数据库商品信息记录并添加到对象的集合中(Arraylist):

#region 获取xml实体类信息
/// <summary>
/// 获取xml实体类信息
/// </summary>
/// <returns></returns>
public static ArrayList GetWebModelInfo()
{
  ArrayList list = new ArrayList();
  string strSQL = "select a.id, a.merchantsID,a.cCode,a.prodCode,a.statue,a.now_number, a.title,a.createtime,a.productimg,a.market_price,a.team_price,a.zhekou_price,a.cityName,a.begin_time,a.end_time,a.description,a.lowBuyNo,b.Address,b.Tel from tg_product as a left join tg_merchants as b on a.merchantsID=b.merchants_id where a.ispublic=1 and statue>-1 and getdate()<dateadd(day,1,a.end_time) order by a.createtime desc";
  DataSet ds = FrameWork.Data.SqlHelper.ReturnDataSet(CommandType.Text, strSQL, null);
  if (ds.Tables[0].Rows.Count > 0)
  {
   foreach (DataRow dr in ds.Tables[0].Rows)
   {
    WebSiteInfo webModel = new WebSiteInfo();
    //城市名称
    webModel.cityName = dr["cityName"].ToString();
    //商品标题
    webModel.title = dr["title"].ToString();
    //商品创建时间
    webModel.createtime = Convert.ToDateTime(dr["createtime"].ToString());
    //商家名称
    webModel.merchants_id = dr["merchantsID"].ToString();
    //商品图片
    webModel.productimg = dr["productimg"].ToString();
    //市场价
    webModel.market_price = Convert.ToDecimal(dr["market_price"].ToString());
    //团购价
    webModel.team_price = Convert.ToDecimal(dr["team_price"].ToString());
    //折扣价
    webModel.zhekou_price = Convert.ToDecimal(dr["zhekou_price"].ToString());
    //开始时间
    webModel.begin_time = Convert.ToDateTime(dr["begin_time"].ToString());
    //结束时间
    webModel.end_time = Convert.ToDateTime(dr["end_time"].ToString());
    //商品说明
    webModel.description = dr["description"].ToString();
    //最低购买数量
    webModel.lowBuNo = Convert.ToInt32(dr["lowBuyNo"].ToString());
    //商家电话
    webModel.Telphone = dr["Tel"].ToString();
    //商家地址
    webModel.Address = dr["Address"].ToString();
    //城市编号
    webModel.cCode = dr["cCode"].ToString();
    //图片文件夹名称
    webModel.folderName = dr["prodCode"].ToString();
    //现在购买人数
    webModel.nownumber = Convert.ToInt32(dr["now_number"].ToString());
    //商品编号
    webModel.productID = Convert.ToInt32(dr["id"].ToString());
    int status = Convert.ToInt32(dr["statue"].ToString());
    switch (status)
    {
     case 0:
      webModel.StatusMessage = "结束";
      break;
     case 1:
      webModel.StatusMessage = "成功";
      break;
    }
    list.Add(webModel);
   }
  }
   return list;
}
#endregion

最后一步将数据库读取来的信息赋值到XML 数据类型中 并序列化成XML文件保存成XML格式的文件读取文件展现到界面:

#region 页面加载 根据数据库商品记录数生成xml文件信息
/// <summary>
/// 页面加载 根据数据库商品记录数生成xml文件信息
/// </summary>
List<url> urlList = null;
urlset urlsetList = new urlset();
protected void Page_Load(object sender, EventArgs e)
{
  if (!Page.IsPostBack)
  {
    ArrayList listinfo=GetWebModelInfo();
    urlList = new List<url>();
   for (int i = 0; i < listinfo.Count; i++)
   {
    WebSiteInfo webInfo = listinfo[i] as WebSiteInfo;
    List<display> displayList = new List<display>();
    display display = new display();
    display.website = "爱购114";
    display.siteurl = "http://www.xxxxx.com/";
    //城市名称
    display.city = webInfo.cityName;
    //商品标题
    display.webSitetitle = webInfo.title;
    //商品图片
    display.image = "http://211.155.235.30/tuangou/" + webInfo.folderName + "/" + webInfo.productimg;
    //商品开始时间
    display.startTime = webInfo.begin_time.ToShortDateString();
    //商品结束时间
    display.endTime = webInfo.end_time.ToShortDateString();
    //市场价
    display.value = Convert.ToDouble(webInfo.market_price);
    //团购价
    display.price = Convert.ToDouble(webInfo.team_price);
    //折扣价
    display.rebate = Convert.ToDouble(webInfo.zhekou_price);
    //现在购买的人数
    display.bought = webInfo.nownumber;
    displayList.Add(display);
    List<data> dataList = new List<data>();
    data data = new data();
    data.displayList = displayList;
    dataList.Add(data);
    url url = new url();
    url.loc = String.Format("http://www.xxxxx.com/todaydetials.aspx", webInfo.productID.ToString());
    url.dataList = dataList;
    urlList.Add(url);
    urlsetList.urlList = urlList;
   }
   try
   {
    XmlSerializerNamespaces xmlns = new XmlSerializerNamespaces();
    xmlns.Add(String.Empty, String.Empty);
    //构造字符串
    StringBuilder sb = new StringBuilder();
    //将字符串写入到stringWriter对象中
    StringWriter sw = new StringWriter(sb);
    //xml序列化对象 typeof(类名)
    XmlSerializer ser = new XmlSerializer(typeof(urlset));
    //把Stream对象和urlset一起传入,序列化出一个字符串sb
    ser.Serialize(sw, urlsetList, xmlns);
    sw.Close();
    string FILE_NAME = HttpContext.Current.Server.MapPath("API/54tuan.xml");
    FileInfo fi = new FileInfo(FILE_NAME);
    //如果文件己经存在则删除该文件 
    if (fi.Exists)
    {
     if (fi.Attributes.ToString().IndexOf("ReadOnly") >= 0) {
      fi.Attributes = FileAttributes.Normal;
     }
     File.Delete(fi.Name);
    }
    //创建文件 并写入字符串
    using (StreamWriter sWrite = File.CreateText(FILE_NAME))
    {
     sWrite.Write(sb.ToString().Replace("encoding=/"utf-16/"", "encoding=/"utf-8/"").Replace("<urlList>", "").Replace("</urlList>", "").Replace("<dataList>", "").Replace("</dataList>", "").Replace("<displayList>", "").Replace("<displayList>", "").Replace("</displayList>", ""));
     sWrite.Close();
    }
    //输出序列化后xml文件
    Response.ClearContent();
    Response.ClearHeaders();
    Response.ContentType = "application/xml";
    Response.WriteFile(HttpContext.Current.Server.MapPath("API/54tuan.xml"));
    Response.Flush();
    Response.Close();
   }
   catch (Exception ex)
   {
    Response.Write(ex.Message);
   }
   finally
   {
   }
   }
}
#endregion

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
