使用Linq將xml解析爲CLR類型

Question

我有以下xml結構，我想將此xml轉換爲CLR對象，但我被卡住了。

<?xml version="1.0" encoding="utf-8"?>

我寫下面的代碼實現相同，但我無法查詢方法部分。 例如，我想加載documentID和SourceID相同的所有方法。

public class ClassDetails 
    { 
     public string Id { get; set; } 
     public string Name { get; set; } 
    } 
    public class AssemblyDetails 
    { 
     public string DllName { get; set; } 
     public List<ClassDetails> Classes { get; set; } 
     public List<string> Methods { get; set; } 
    } 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      var document = XDocument.Load("test11.xml"); 
      var query = from descendantNode in document.Descendants("sourceFiles") 
         select new AssemblyDetails() 
         { 
          DllName = document.Root.Attribute("assembly").Value, 
          Classes = (from x in document.Descendants("document") 
             select new ClassDetails 
             { 
              Id=x.Attribute("id").Value, 
              Name=x.Attribute("url").Value 
             }).ToList(), 
          Methods = (from y in document.Descendants("method").Elements("seqPoint") 
            where y.Attribute("sourceId").Value=="documentID" 
            select y.Document.Root.Attribute("name").Value).ToList() 
         }; 

      int i=10; 
     } 

Answer 1

XDocument xdoc = XDocument.Load(path_to_xml); 
var documentIds = xdoc.Descendants("document") 
         .Select(d => (int)d.Attribute("id")); 
         .ToList(); 

var methodNames = xdoc 
    .Descendants("method") 
    .Where(m => m.Descendants("seqPoint") 
       .Any(sp => documentIds.Contains((int)sp.Attribute("sourceId")))) 
    .Select(m => (string)m.Attribute("name")); 

首先查詢獲取所有文檔ID。

第二查詢獲取的方法，它具有特定的文件sourceId至少一個seqPoint方法名。
