c# - 如何使用 LINQ to XML 将 List 序列化为 XML？

Question

我有这个通用列表

   List<zil> listKD = new List<zil>
            {
            new zil{day="Mon",c="1",S1="08:00",S2="08:40",S3="08:47"},
            new zil{day="Mon",c="2",S1="08:50",S2="09:30",S3="09:37"},
            new zil{day="Mon",c="3",S1="09:40",S2="10:20",S3="10:27"},
            new zil{day="Mon",c="4",S1="10:30",S2="11:10",S3="11:17"},
            new zil{day="Tue",c="1",S1="08:00",S2="08:40",S3="08:47"},
            new zil{day="Tue",c="2",S1="08:50",S2="09:30",S3="09:37"},
            new zil{day="Wed",c="1",S1="08:00",S2="08:40",S3="08:47"},
            new zil{day="Wed",c="2",S1="08:50",S2="09:30",S3="09:37"},
            new zil{day="Thu",c="1",S1="08:00",S2="08:40",S3="08:47"},
            new zil{day="Thu",c="2",S1="08:50",S2="09:30",S3="09:37"},
            new zil{day="Thu",c="3",S1="09:40",S2="10:20",S3="10:27"},
            new zil{day="Fri",c="1",S1="08:00",S2="08:40",S3="08:47"},
            new zil{day="Fri",c="2",S1="08:50",S2="09:30",S3="09:37"},
            new zil{day="Fri",c="3",S1="09:40",S2="10:20",S3="10:27"},
            new zil{day="Fri",c="4",S1="10:30",S2="11:10",S3="11:17"},
            };

我想保存这个列表 xml 但我不喜欢这个 xml 文件

这段代码不适合我想要的

XElement zXml = new XElement("Days",           
           from g in listKD
           select new XElement("Day",
                        new XAttribute("id", g.Day),
                        new XElement("clock",
                        new XAttribute("id", g.c),
                      new XElement("s1", g.s1),
                      new XElement("s2", g.s2),
                      new XElement("s3", g.s3)
                      )));

        ZXml.Save("abc.xml");

谢谢...

我想你还没有按天分组；也许是这样的:

var el = new XElement("Days",
    from z in listKD
    group z by z.day into tmp
    select new XElement("Day",
        new XAttribute("id", tmp.Key),
        from item in tmp
        select new XElement("clock",
            new XAttribute("id", item.c),
            new XElement("s1", item.S1),
            new XElement("s2", item.S2),
            new XElement("s3", item.S3))
            ));
string s = el.ToString(); // or save etc

更新重新评论；扭转它，像这样:

        XElement parsed = XElement.Parse(s);
        var newList = (from day in parsed.Elements("Day")
                       from clock in day.Elements("clock")
                       select new zil
                       {
                           day = (string)day.Attribute("id"),
                           c = (string)clock.Attribute("id"),
                           S1 = (string)clock.Element("S1"),
                           S2 = (string)clock.Element("S2"),
                           S3 = (string)clock.Element("S3")
                       }).ToList();

过滤到特定日期:

                       from day in parsed.Elements("Day")
                       where (string)day.Attribute("id") == "Mon"
                       from clock in day.Elements("clock")
                       ...
