对 XElement 进行排序

我有一个 XElement，其映射如下：

<book>
    <author>sadfasdf</author>
    <title>asdfasdf</title>
    <year>1999</year>
</book>
<book>
    <author>asdfasdf</author>
    <title>asdfasdf</title>
    <year>1888</year>
</book>
<book>
    <author>asdfsdf</author>
    <title>asdfasdf</title>
    <year>1777</year>
</book>

如何按作者、书名或年份对书籍进行排序？谢谢

你想要_____吗read（查询）特定顺序的数据，还是您实际上想要对 xml 中的数据重新排序？要按特定顺序读取，只需使用 LINQOrderBy method:

    var qry = from book in el.Elements("book")
              orderby (int)book.Element("year")
              select new
              {
                  Year = (int)book.Element("year"),
                  Title = (string)book.Element("title"),
                  Author = (string)book.Element("author")
              };

（已编辑）更改 xml 比较棘手......也许是这样的：

    var qry = (from book in el.Elements("book")
               orderby (int)book.Element("year")
               select book).ToArray();

    foreach (var book in qry) book.Remove();
    foreach (var book in qry) el.Add(book);
