本篇內(nèi)容介紹了“如何實(shí)現(xiàn)asp.net類序列化生成xml文件”的有關(guān)知識(shí)，在實(shí)際案例的操作過(guò)程中，不少人都會(huì)遇到這樣的困境，接下來(lái)就讓小編帶領(lǐng)大家學(xué)習(xí)一下如何處理這些情況吧！希望大家仔細(xì)閱讀，能夠?qū)W有所成！
在望都等地區(qū)，都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局，加強(qiáng)發(fā)展的系統(tǒng)性、市場(chǎng)前瞻性、產(chǎn)品創(chuàng)新能力，以專注、極致的服務(wù)理念，為客戶提供
成都網(wǎng)站制作、網(wǎng)站建設(shè) 網(wǎng)站設(shè)計(jì)制作定制開(kāi)發(fā),公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),
成都品牌網(wǎng)站建設(shè),
網(wǎng)絡(luò)營(yíng)銷推廣,成都外貿(mào)網(wǎng)站制作,望都網(wǎng)站建設(shè)費(fèi)用合理。
根據(jù)設(shè)計(jì)的需求需要開(kāi)發(fā)多個(gè)商品的API 原XML文件如下：
http://www.xxxxx.com/todaydetials.aspx?id=143
愛(ài)購(gòu)114
http://www.xxxxx.com/

現(xiàn)在需求是要根據(jù)數(shù)據(jù)庫(kù)有幾條商品信息 相應(yīng)的API XML文件出現(xiàn)幾個(gè)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(gè)商品XML的信息 實(shí)現(xiàn)代碼如下：
首先定義好XML 各個(gè)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 urlList
{

}
}
public class url
{
public string loc
{

}
public List dataList
{

}
}
public class data
{
public List displayList
{
get;

}
}
public class display
{
public string website

}
public string siteurl
{

}
public string city

public string webSitetitle

public string image

public string startTime

public string endTime

public double value

}
public double price
{
get;

public double rebate
{
get;

}
public int bought
{
get;
set;
}
}
#endregion第二步：#region 定義獲取網(wǎng)站信息實(shí)體類

#endregion第三步：獲取數(shù)據(jù)庫(kù)商品信息記錄并添加到對(duì)象的集合中（Arraylist）：
#region 獲取xml實(shí)體類信息

{
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

最后一步將數(shù)據(jù)庫(kù)讀取來(lái)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：
