Question

<?xml version="1.0" encoding="utf-8" ?>
<reportgroups>
  <Reportgroup id="1" name="reportGroup1">
    <report id="1" name="report1" isSheduled="false"></report>
    <report id="2" name="report2"  isSheduled="false"></report>
    <report id="3" name="report3"  isSheduled="false"></report>
  </Reportgroup>
  <Reportgroup id="2" name="reportGrouop2">
    <report id="4" name="report4"  isSheduled="false"></report>
  </Reportgroup>
  <Reportgroup id="3" name="reportGrouop3"></Reportgroup>
</reportgroups>

我有课程

public class Reportgroup
{
    public int id { get; set; }
    public string name  { get; set; }
}

public class Report
{
    public int id { get; set; }
    public string name { get; set; }
    public bool isSheduled { get; set; }
}

如何使用linq将此xml读取到Reportgroup对象列表中。它的语法是什么？报告组列表中的每个项目都应包含报告列表

您的Reportgroup课程似乎错过了与Report相关联的方法。无论如何，你可以这样读（对你的课程进行一些调整）：

public class ReportGroup // CamelCase!!!
{
    public int Id { get; set; }
    public string Name  { get; set; }
    public List<Report> Reports { get; set; } // need to hold the associated reports
}

public class Report
{
    public int Id { get; set; }
    public string Name { get; set; }
    public bool IsSheduled { get; set; }
}

var doc = XDocument.Load("path/to/file.xml");
var reportGroups = doc.Element("reportgroups")
    .Elements("Reportgroup")
    .Select(rg => new ReportGroup
    {
        Id = (int)rg.Attribute("id"),
        Name = (string)rg.Attribute("name"),
        Reports = rg.Elements("report")
            .Select(r => new Report
            {
                Id = (int)r.Attribute("id"),
                Name = (string)r.Attribute("name"),
                IsScheduled = (bool)r.Attribute("isScheduled"),
            }).ToList();
    }).ToList();
