这是我的XML:
<home>
<contents>
<row>
<content>
<idContent>1</idContent>
<title>title1</title>
</content>
<content>
<idContent>2</idContent>
<title>title2</title>
</content>
</row>
<row>
<content>
<idContent>3</idContent>
<title>title3</title>
</content>
<content>
<idContent>4</idContent>
<title>title4</title>
</content>
</row>
</contents>
我想将此信息存储在对象列表中
列出myList = ...
内容可以是:
int idContent;
string title;
int row_number;
每个Content对象都必须将行存储在XML中。
这样做的最佳方式是什么?

假设row_number
只是与XML中出现的顺序相关的序列,那么你可以这样做:
var doc = XDocument.Parse(xml);
var contents = doc.Descendants("row")
.Select((e, index) => new {Row = e, RowIndex = index})
.SelectMany(x => x.Row.Elements("content").Select(e => new {Content = e, x.RowIndex}))
.Select(x => new Content
{
IdContent = (int)x.Content.Element("idContent"),
Title = (string)x.Content.Element("title"),
RowNumber = x.RowIndex + 1
}).ToList();

我能想到的最好的解决方案 - 虽然它没有使用Linq到XML - 是将XML文档提供给其中一个不同的XML Schema生成器,如http://www.freeformatter.com/xsd-generator.html,并将生成的Schema管道直接输入xsd.exe (见https://msdn.microsoft.com/en-us/library/x6c1kb0s.aspx)。生成的代码可用于读取(和写入)您提供的XML文档,您当然可以将Linq应用于此集合上的对象。
但是,由于您提到了尚未出现在示例XML中的row_number字段,因此您必须将其添加到XML中,或者之后手动编辑XML Schema。

我将此方法用于类似的场景:
public static Object CreateObject(string XMLString, Object YourClassObject)
{
System.Xml.Serialization.XmlSerializer oXmlSerializer = new System.Xml.Serialization.XmlSerializer(YourClassObject.GetType());
//The StringReader will be the stream holder for the existing XML file
YourClassObject = oXmlSerializer.Deserialize(new System.IO.StringReader(XMLString));
//initially deserialized, the data is represented by an object without a defined type
return YourClassObject;
}
使用此方法,您可以从XML String创建类对象。我还没有在您的方案中对其进行测试,但您可以将其用于关注home
类的对象:
public class home
{
public List<row> contents;
}
public class row
{
public List<content> content;
}
public class content
{
public int idContent;
public string title;
}
<强> USAGE:强>
home h = new home();
h = (home)CreateObject(xml, h);
请记住,变量和类名必须与XML节点完全相同。
<强> EXTRA:强>
如果要将类对象转换为XML String,请使用以下方法:
string CreateXML(Object YourClassObject)
{
XmlDocument xmlDoc = new XmlDocument(); //Represents an XML document,
// Initializes a new instance of the XmlDocument class.
XmlSerializer xmlSerializer = new XmlSerializer(YourClassObject.GetType());
// Creates a stream whose backing store is memory.
using (MemoryStream xmlStream = new MemoryStream())
{
xmlSerializer.Serialize(xmlStream, YourClassObject);
xmlStream.Position = 0;
//Loads the XML document from the specified string.
xmlDoc.Load(xmlStream);
return xmlDoc.InnerXml;
}
}
