我有像这样的xml结构。任何人都可以帮助使用简单的linq函数来读取此xml结构.itendEntry节点根据数据重复。我尝试使用下面的方法读取xml,但我在列表中没有记录。这种方法在这里是正确的方式来获取细节...
List<CX_ITEMLIST> sList =
(from e in XDocument.Load(param.FileName).Root.Elements("itemEntry")
select new CX_ITEMLIST
{
TITLE = (string)e.Element("title"),
YEAR = (string)e.Element("year"),
ITEMNAME = (string)e.Element("itemname"),
CATRYLIST =
(
from p in e.Elements("categorylist").Elements("categories")
select new CATLIST
{
IDTYPE = (string)p.Element("categoryid"),
IDNUMBER = (string)p.Element("categoryName")
}).ToList()
}).ToList();
<itemslist>
<itemInformation>
<itemdate>01/23/2014</itemdate>
<itemcount>57</itemcount>
</itemInformation>
<itemEntry>
<title>Title1</title>
<year>2013</title>
<itemname>testname</itemname>
<categorylist>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
</categorylist>
</itemEntry>
<itemEntry>
<title>Title1</title>
<year>2013</title>
<itemname>testname</itemname>
<categorylist>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
<categories>
<categoryid>Category1</categoryid>
<categoryName>Category2</categoryName>
</categories>
</categorylist>
</itemEntry>
</itemslist>

您应该尝试使用XDocument。
XDocument xdoc = XDocument.Load("file.xml");

System.Xml.XLinq命名空间包含一些很棒的对象,可以轻松实现。
var xDoc = XDocument.Parse(xml); // load your xml string, or use XDocument.Load() to load an xml file
var itemEntries = xDoc
.Root // refers to itemEntries node
.Descendants("itemEntry"); // gets all itemEntry nodes in an IEnumerable object
这会让你获得所有itemEntry节点的IEnumerable<XNode>
。
从那里你可以做你需要的,将值保存到业务对象等等。

上面的方法工作正常,我发现问题,我的xml标签有namespace属性。我试图获取命名空间并在阅读
时将其附加到ElementsXNamespace ns = xDocument.Root.Attribute("xmlns").Value;
List<CX_ITEMLIST> sList =
(from e in XDocument.Load(param.FileName).Root.Elements(ns + "itemEntry")
select new CX_ITEMLIST
{
TITLE = (string)e.Element(ns + "title"),
YEAR = (string)e.Element(ns + "year"),
ITEMNAME = (string)e.Element(ns + "itemname"),
CATRYLIST =
(
from p in e.Elements(ns + "categorylist").Elements(ns + "categories")
select new CATLIST
{
IDTYPE = (string)p.Element(ns + "categoryid"),
IDNUMBER = (string)p.Element(ns + "categoryName")
}).ToList()
}).ToList();
