xml to linq C#实例 类和xml文件互转换
xml文件
<?xml version="1.0" encoding="utf-8" ?>
<User>
<UserID>34e4257b-b364-4ddc-979d-bcfbb5288f5a</UserID>
<Films>
<Film>
<Title>蜘蛛侠</Title>
<ID>30</ID>
</Film>
<Film>
<Title>天生一对</Title>
<ID>65</ID>
</Film>
<Film>
<Title>山楂树之恋</Title>
<ID>130</ID>
</Film>

类1
public class FavoritesInfo
{
public string UserID { get; set; }
private List<FilmInfo> _ListFilm = new List<FilmInfo>();
public List<FilmInfo> ListFilm
{
get { return _ListFilm; }
set { _ListFilm=value;}
}
}
类2
public class FilmInfo
{
public string ID { get; set; }
public string Title { get; set; }
public string Img { get; set; }
public string Tags { get; set; }
//public string FlashLink { get; set; }
public List<FlashLinkInfo> ListFlash { get; set; }

public string Intro { get; set; }

}
读xml文件 转成类
public List<FavoritesInfo> GetFavorites()
{
List<FavoritesInfo> listFavorites = new List<FavoritesInfo>();
// 读xml文件
// string xmlFile = Server.MapPath("DvdList.xml"); //获取XML文件的路径
// XDocument doc = XDocument.Load(xmlFile);
string strXml = ReadXmlData();
if (!string.IsNullOrEmpty(strXml))
{
byte[] bs = Encoding.UTF8.GetBytes(strXml);
MemoryStream ms = new MemoryStream(bs);
XDocument xdoc = XDocument.Load(ms);
listFavorites = (
from favoriteinfo in xdoc.Descendants("User")
select new FavoritesInfo
{
UserID = favoriteinfo.Element("UserID").Value.Trim(),
ListFilm = (
from filminfo in favoriteinfo.Descendants("Film") // xdoc.Descendants("rows")
select new FilmInfo
{
ID = filminfo.Element("ID").Value,
Title = filminfo.Element("Title").Value,
}
).ToList(),
}
).ToList();
}
return listFavorites;
}
C#类转成xml文件
public void SaveFavorites(FavoritesInfo favoriteInfo)
{
if (favoriteInfo == null) return;
XElement xml = new XElement("User", new XElement("UserID", favoriteInfo.UserID),
new XElement("Films",
from p in favoriteInfo.ListFilm
select new XElement("Film",
new XElement("Title", p.Title),
new XElement("ID", p.ID)
)
)
);
// 保存xml文件 到磁盘上
//CreatXmlData(xml.ToString());
XDocument doc = new XDocument(new XDeclaration("1.0", "utf-8", ""));
doc.Add(xml);
doc.Save(fileName);
}
如果xml文件类似如下
<?xml version="1.0" encoding="utf-8" ?>
<Armys>
<Army>
<ArmyID>12</ArmyID>
<ArmyName>集团军A</ArmyName>
<ArmyNameEn></ArmyNameEn>
<BtnBG></BtnBG>
<ElectronicExe></ElectronicExe>
<ListMemorabilia>
<PDFFile>
<PDFID>fc855a91-55c6-40e9-a527-d64f106559e9</PDFID>
<PDFFileName>《iPhone开发基础教程》.pdf</PDFFileName>
<PDFFilePath>F:\ DownLoad\《iPhone开发基础教程》.pdf</PDFFilePath>
</PDFFile>
<PDFFile>
<PDFID>c21c96bf-ae91-4aa7-8697-d8685a6a4bc6</PDFID>
<PDFFileName>lustre2010_controlsurface_user_guide.pdf</PDFFileName>
<PDFFilePath>F:\DownLoad\lustre2010_controlsurface_user_guide.pdf</PDFFilePath>
</PDFFile>
</ListMemorabilia>
<ListMemoriesHistorical >
<PDFFile>
<PDFID>fc855a91-55c6-40e9-a527-d64f106559e9</PDFID>
<PDFFileName>《iPhone开发基础教程》.pdf</PDFFileName>
<PDFFilePath>F:\DownLoad\《iPhone开发基础教程》.pdf</PDFFilePath>
</PDFFile>
</ListMemoriesHistorical>
<ListPicture />
<ListStatisticalForms />
</Army>
</Armys>
则 获取数据写法
string XMLFilePath = "c:\Data\ArmyData.xml";
public List<ArmyInfo> LoadData()
{
List<ArmyInfo> list = new List<ArmyInfo>();
var cities = from c in XElement.Load(XMLFilePath).Elements("Army") select c;
foreach (var item in cities)
{
ArmyInfo cityInfo = new ArmyInfo

ArmyNameEn = item.Element("ArmyNameEn") == null ? string.Empty : item.Element("ArmyNameEn").Value,
BtnBG = item.Element("BtnBG") == null ? string.Empty : item.Element("BtnBG").Value,
ElectronicExe = item.Element("ElectronicExe") == null ? string.Empty : item.Element("ElectronicExe").Value,
ListMemorabilia = (

select new PDFFileInfo {

}).ToList(),
ListMemoriesHistorical = (

select new PDFFileInfo
{
PDFFileName = pdfInfo.Element("PDFFileName") == null ? string.Empty : pdfInfo.Element("PDFFileName").Value,
PDFFilePath = pdfInfo.Element("PDFFilePath") == null ? string.Empty : pdfInfo.Element("PDFFilePath").Value,

}).ToList(),
ListPlay = (

select new PlayInfo

}
).ToList(),
// SectionNamePinYin = item.Element("SectionNamePinYin").Value
};
list.Add(cityInfo);
}
return list;
}
