如何从多个后代获取XElements值请参阅我的XML文档：

<?xml version="1.0" encoding="UTF-8"?>
<root>

<WithoutGroup>
   <StudentId>21</StudentId>
   <StudentName>Photo</StudentName>
   <Image>dshdsdhshdsghs</Image>

我想＆＃34;学生姓名＆＃34;和＆＃34;学生ID＆＃34;，我该如何处理条件？任何帮助将不胜感激!!

这是代码：

 XDocument doc = XDocument.Parse(e.Result);

            List<STUDENT> list = new List<STUDENT>();

            list = (from query in doc.Descendants("WithoutGroup")
                       select new STUDENT
                       {
                           stdId = Convert.ToInt64(query.Element("StudentId").Value),
                           stdName = query.Element("StudentName").Value,
                           Icon = getImage(query.Element("Image").Value),

                       }).ToList();

如果您确定<StudentID>始终跟随<StudentName>，则可以选择所有<StudentID>个后代，并使用XElement.NextNode获取相应的<StudnetName>：< / p>

list = (from id in doc.Descendants("StudentId")
        select new STUDENT
                    {
                        stdId = (Int64)id,
                        stdName = (string)(XElement)id.NextNode
                    }).ToList();
