這篇文章主要介紹了asp.net類序列化生成xml文件的方法,結(jié)合實(shí)例形式較為詳細(xì)的分析了asp.net序列化生成xml文件的具體步驟與相關(guān)實(shí)現(xiàn)技巧,需要的朋友可以參考下

本文實(shí)例講述了asp.net類序列化生成xml文件的方法。分享給大家供大家參考，具體如下：

根據(jù)設(shè)計(jì)的需求需要開發(fā)多個商品的API 原XML文件如下：

<urlset>
 <url>
  <loc>http://www.xxxxx.com/todaydetials.aspx?id=143</loc>
  <data>
   <display>
    <website>愛購114</website>
    <siteurl>http://www.xxxxx.com/</siteurl>
    <city>杭州</city>
    <webSitetitle></webSitetitle>
    <image></image>
    <startTime>2011-2-9</startTime>
    <endTime>2011-2-15</endTime>
    <value>3880</value>
    <price>2088</price>
    <rebate>0.53</rebate>
    <bought>0</bought>
   </display> 
  </data>
 </url>
</urlset>

現(xiàn)在需求是要根據(jù)數(shù)據(jù)庫有幾條商品信息相應(yīng)的API XML文件出現(xiàn)幾個URL節(jié)點(diǎn)！采用類序列化成XML文件然后讀取相應(yīng)生成的XML文件就可以展示多個商品XML的信息實(shí)現(xiàn)代碼如下：

首先定義好XML 各個節(jié)點(diǎn)的數(shù)據(jù)及父子節(jié)點(diǎn)的關(guān)系類：

#region 定義數(shù)據(jù)實(shí)體類xml數(shù)據(jù)結(jié)構(gòu)
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 定義獲取網(wǎng)站信息實(shí)體類

public class WebSiteInfo
{
  /// <summary>
  /// 商品標(biāo)題
  /// </summary>
  public string title { get; set; }
  /// <summary>
  /// 商品發(fā)布時(shí)間
  /// </summary>
  public DateTime createtime { get; set; }
  /// <summary>
  /// 商品圖片
  /// </summary>
  public string productimg { get; set; }
  /// <summary>
  /// 市場價(jià)
  /// </summary>
  public decimal market_price { get; set; }
  /// <summary>
  /// 團(tuán)購價(jià)

  public decimal team_price { get; set; }
  /// <summary>
  /// 折扣價(jià)
  /// </summary>
  public decimal zhekou_price { get; set; }
  /// <summary>
  /// 城市名稱 
  /// </summary>
  public string cityName { get; set; }
  /// <summary>
  /// 商品開始時(shí)間
  /// </summary>
  public DateTime begin_time { get; set; }
  /// <summary>
  /// 結(jié)束時(shí)間
  /// </summary>
  public DateTime end_time { get; set; }
  /// <summary>
  /// 商家名稱
  /// </summary>
  public string merchants_id { get; set; }
  /// <summary>
  /// 本單詳情
  /// </summary>
  public string description { get; set; }
  /// <summary>
  /// 最低購買人數(shù)
  /// </summary>
  public int lowBuNo { get; set; }
  /// <summary>
  /// 商家地址
  /// </summary>
  public string Address { get; set; }
  /// <summary>
  /// 商家電話
  /// </summary>
  public string Telphone { get; set; }
  /// <summary>
  /// 城市區(qū)號
  /// </summary>
  public string cCode { get; set; }
  /// <summary>
  /// 文件夾名稱
  /// </summary>
  public string folderName { get; set; }
  /// <summary>
  /// 團(tuán)購狀態(tài) 
  /// </summary>
  public string StatusMessage { get; set; }
  /// <summary>
  /// 現(xiàn)在購買人數(shù)
  /// </summary>
  public int nownumber { get; set; }
  /// <summary>
  /// 商品編號
  /// </summary>
  public int productID { get; set; }
}
#endregion

第三步：獲取數(shù)據(jù)庫商品信息記錄并添加到對象的集合中（Arraylist）：

#region 獲取xml實(shí)體類信息
/// <summary>
/// 獲取xml實(shí)體類信息
/// </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();
    //城市名稱
    webModel.cityName = dr["cityName"].ToString();
    //商品標(biāo)題
    webModel.title = dr["title"].ToString();
    //商品創(chuàng)建時(shí)間
    webModel.createtime = Convert.ToDateTime(dr["createtime"].ToString());
    //商家名稱
    webModel.merchants_id = dr["merchantsID"].ToString();
    //商品圖片
    webModel.productimg = dr["productimg"].ToString();
    //市場價(jià)
    webModel.market_price = Convert.ToDecimal(dr["market_price"].ToString());
    //團(tuán)購價(jià)
    webModel.team_price = Convert.ToDecimal(dr["team_price"].ToString());
    //折扣價(jià)
    webModel.zhekou_price = Convert.ToDecimal(dr["zhekou_price"].ToString());
    //開始時(shí)間
    webModel.begin_time = Convert.ToDateTime(dr["begin_time"].ToString());
    //結(jié)束時(shí)間
    webModel.end_time = Convert.ToDateTime(dr["end_time"].ToString());
    //商品說明
    webModel.description = dr["description"].ToString();
    //最低購買數(shù)量
    webModel.lowBuNo = Convert.ToInt32(dr["lowBuyNo"].ToString());
    //商家電話
    webModel.Telphone = dr["Tel"].ToString();
    //商家地址
    webModel.Address = dr["Address"].ToString();
    //城市編號
    webModel.cCode = dr["cCode"].ToString();
    //圖片文件夾名稱
    webModel.folderName = dr["prodCode"].ToString();
    //現(xiàn)在購買人數(shù)
    webModel.nownumber = Convert.ToInt32(dr["now_number"].ToString());
    //商品編號
    webModel.productID = Convert.ToInt32(dr["id"].ToString());
    int status = Convert.ToInt32(dr["statue"].ToString());
    switch (status)
    {
     case 0:
      webModel.StatusMessage = "結(jié)束";
      break;
     case 1:
      webModel.StatusMessage = "成功";
      break;
    }
    list.Add(webModel);
   }
  }
   return list;
}
#endregion

最后一步將數(shù)據(jù)庫讀取來的信息賦值到XML 數(shù)據(jù)類型中并序列化成XML文件保存成XML格式的文件讀取文件展現(xiàn)到界面：

#region 頁面加載 根據(jù)數(shù)據(jù)庫商品記錄數(shù)生成xml文件信息

    ser.Serialize(sw, urlsetList, xmlns);
    sw.Close();
    string FILE_NAME = HttpContext.Current.Server.MapPath("API/54tuan.xml");
