XDocument加载到ToList

我在XDocument的帮助下加载.xml文件。我成功地读了.xml文件。

C#代码:

XDocument doci = XDocument.Load(path);
var mijav = from r in doci.Descendants("Configuration").Descendants("DayRoutine").Descendants("DayRoutine").Where(r => (int)r.Attribute("ID") == 4)
            select new
            {
                Button = r.Element("Button").Value,
                DataPoints = r.Elements("DayRoutinePoints").Select(c => (string)c.Value).ToList(),
            };

我遇到的问题是DataPoint变量。我在“one”数组中只获得一个值,并且所有点都在此数组中写入。如何为每条引线划分这些数据?

现在

DataPoint变量:

"00:00:00, 44004:45:00, 48013:35:00, 60015:00:00, 41519:55:00, 600"

以XML格式记录数据以及我希望如何:

"00:00:00, 440
 04:45:00, 480
 13:35:00, 600
 15:00:00, 415
 19:55:00, 600"

我的XML文件:

<blabla>
   <Infos>
      <ConfigurationName>XXConfigurationName</ConfigurationName>
     <DateSaved>14.10.2015 13:14:01</DateSaved>
   </Infos>
 <Configuration>
    <DayRoutine>
       <DayRoutine ID="4">
          <Button>1</Button>
          <SetupOption>StaticBasic_DoffEoff</SetupOption>
          <DayRoutinePoints>
             <Point0>00:00:00, 440</Point0>
             <Point1>04:45:00, 480</Point1>
             <Point2>13:35:00, 600</Point2>
             <Point3>15:00:00, 415</Point3>
             <Point4>19:55:00, 600</Point4>
          </DayRoutinePoints>
       </DayRoutine>
   </DayRoutine>
  </Configuration>
</blabla>

使用此:

DataPoints = String.Join(" ", r.Elements("DayRoutinePoints")
.Elements()
.Select(x=>x.Value.ToString()+Environment.NewLine))

试试这个:

XDocument doci = XDocument.Load(path);
        var mijav =
            doci.Descendants("Configuration")
                .Descendants("DayRoutine")
                .Descendants("DayRoutine")
                .Where(r => (int) r.Attribute("ID") == 4)
                .Select(r => new
                {
                    Button = r.Element("Button").Value,
                    DataPoints =
                        r.Elements("DayRoutinePoints").Elements()
                            .Select(c => (string) c.Value)
                            .ToList(),
                });

答案 2 :(得分:1)

目前,您正在选择DayRoutinePoints的所有DayRoutine元素,并为您提供单个元素。然后,您正在读取其值,即所有嵌套点元素的值。这就是为什么你有单值的数组。

您需要做的一切 - 选择单个DayRoutinePoints元素并获取它的子元素:

DataPoints = r.Element("DayRoutinePoints").Elements().Select(c => (string)c).ToList(),

注意:使用XPath,您的解析看起来更简单(我省略了将点转换为列表)

from r in doci.XPathSelectElements("//Configuration/DayRoutine/DayRoutine[@ID=4]")    
select new
{
    Button = (string)r.Element("Button"),
    DataPoints = from p in r.Element("DayRoutinePoints").Elements()
                 select (string)p
};

要解决选择问题,您需要选择节点<DayRoutinePoints>的所有后代并获取它们的值。

DataPoints = r.Descendants("DayRoutinePoints")
              .Descendants().Select(c => (string)c.Value).ToList(),

原始代码基本上采用了DayRoutinePoints节点的内部文本,最终成为节点的内容,并删除了所有XML。
