              </Shelter>
            ---

</Shelters>

我尝试使用后代，我得到了空值。寻找带有XElement的Linq来处理它。请帮助。

Answer 1

我相信这会给你想要的结果。这是来自此处修改为您的问题LINQ to read XML

的其他帖子的示例

XDocument xdoc = XDocument.Load("Data.xml");
var lv1s = from lv1 in xdoc.Descendants("Shelter")
           select new
           {
                ShelterType = lv1.Element("ShelterType").Value
           };
foreach (var lv in lv1s)
{
    Console.WriteLine(lv.ShelterType);
}

试试这个

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);

            List<XElement> sheltertype = doc.Descendants("Shelter")
                .Where(x => (x.Element("ShelterType").Value == "Loft") || (x.Element("ShelterType").Value == "Condos")).ToList();
        }
    }
}
