XML 有点长！

我现在的结果如下图：


但是我还希望 把 没有 timeSlip 那个节点 TimeSheet 取出来！相当于　表的左连接！

XElement myDoc = XElement.Load("C:\\query_timesheet_result.xml");

        var xml =
             from ele in myDoc.Elements("result").Elements("collection").Elements("timeSheet")
             from ele2 in ele.Elements("timeslip")
             select new
             {
                 timeSheetCode = ele.Element("code").Value,
                 timeSheettotalHours = ele.Element("totalHours").Value,
                 timeslipCode = ele2.Element("code").Value,

             };



        foreach (var item in xml)
        {
            Response.Write(item + "<br/>");
        }

学习中···

不错不错
