我想以此作为历史对象来创建和反对.
public class History
{
public string Name { get; set; }
public string Number { get; set; }
public List<Item> Items { get; set; }
}
var xElement = XDocument.Parse(xmlString);
XElement body = (XElement)xElement.Root.LastNode;
XElement historyElement = (XElement)body.LastNode;
var history = new History
{
Name = (string)historyElement.Element("Name"),
Number = (string)historyElement.Element("Number"),
Items = (
from e in historyElement.Elements("Item")
select new Item
{
CraeteDate = DateTime.Parse(e.Element("CreateDate").Value),
Type = (string)e.Element("Type").Value,
Description = string.Join(",",
from p in e.Elements("Description") select (string)p.Element("Description"))
}).ToList()
};
为什么这不起作用？
该值始终为空.
似乎“ historyElement.Element(“ Name”)“始终为空,即使有一个元素和该元素的值.
知道我想念什么吗？
谢谢
解决方法:
这是由于名称空间所致,请尝试执行以下操作：
XNamespace ns = "http://schemas.microsoft.com/search/local/ws/rest/v1";// the namespace you have in the history element
var xElement = XDocument.Parse(xmlString);
var history= xElement.Descendants(ns+"History")
.Select(historyElement=>new History{ Name = (string)historyElement.Element(ns+"Name"),
Number = (string)historyElement.Element(ns+"Number"),
Items = (from e in historyElement.Elements(ns+"Item")
select new Item
{
CraeteDate= DateTime.Parse(e.Element(ns+"CreateDate").Value),
Type = (string) e.Element(ns+"Type").Value,
Description= string.Join(",",
from p in e.Elements(ns+"Description") select (string)p)
}).ToList()
}).FirstOrDefault();
