C＃的LINQ to XML - 解析嵌套的對象列表

Question

我現在有一個是這樣的（空白和橢圓增加了可讀性）一個XML文件格式：

<root> 
    <Module>   //Start with list of Modules 
     <ModuleParams> 
     </ModuleParams> 
    </Module> 
    ... 

    <DetectLine>  //Now a list of DetectLines 
     <DetectLineParams> 
     </DetectLineParams> 

     <Channels> //List of Channels embedded in each DetectLine 
      <Channel> 
       <ChannelParams> 
       </ChannelParams> 
      </Channel> 
      ... 

     </Channels> 
    </DetectLine> 
    ... 

</root> 

類結構如下：

public class Module 
{ 
    public ModuleParams { get; set; } 
} 

public class DetectLine 
{ 
    public DetectLineParams { get; set; } 
    public List<Channel> Channels { get; set; } 
} 

public class Channel 
{ 
    public ChannelParams { get; set; } 
} 

模塊和檢測線列表很容易用Linq解析XML。但是，解析每個DetectLine的頻道列表對我來說並不那麼明顯。這甚至可以用Linq到XML來完成嗎？我寧願不必重構結構以使用XMLSerializer。

初始代碼（OpenXML的一個打開文件對話框已經簽好名。）：

List<Module> myModules; 
List<DetectLine> myDetectLines; 
XDocument config = XDocument.Load(openXML.FileName); 

myModules = 
     (from myElements in config.Descendants("Module") 
      select new Module() 
      { 
       ModuleParam1 = (string)myElements.Element("ModuleParam1"), 
       ModuleParam2 = (string)myElements.Element("ModuleParam2"), 
       ... 
      }).ToList<Module>(); 

myDetectLines = 
      (from myElements in config.Descendants("DetectLine") 
      select new DetectLine() 
      { 
       DetectLineParam1 = (string)myElements.Element("ModuleParam1"), 
       DetectLineParam2 = (string)myElements.Element("ModuleParam2"), 
       ... 

       // ?? Add Channels list here somehow... 
      }).ToList<DetectLine>(); 

Answer 1

隨着

XElement detectLine = XElement.Parse(@"<DetectLine>  
     <DetectLineParams> 
     </DetectLineParams> 

     <Channels>  
      <Channel> 
       <ChannelParams> 
       </ChannelParams> 
      </Channel> 
      ... 

     </Channels> 
    </DetectLine> 
"); 

，你可以做如

DetectLine dl1 = new DetectLine() { 
    DetectLineParams = ..., 
    Channels = (from channel in detectLine.Element("Channels").Element("Channel") 
      select new Channel() { 
       ChannelParams = new ChannelParams() { ... = channel.Element("ChannelParams").Value } 
      }).ToList(); 

我們確實需要看到更多具體的C＃類代碼來說明如何設置完整查詢。

[編輯] 以配合你現在已經發布的代碼：

myDetectLines = 
      (from myElements in config.Descendants("DetectLine") 
      select new DetectLine() 
      { 
       DetectLineParam1 = (string)myElements.Element("ModuleParam1"), 
       DetectLineParam2 = (string)myElements.Element("ModuleParam2"), 
       ... 

       Channels = (from channel in myElements.Element("Channels").Element("Channel") 
       select new Channel() { 
        ChannelParams = new ChannelParams() { ... = channel.Element("ChannelParams").Value } 
       }).ToList(); 
      }).ToList<DetectLine>();
