如何根據元素或屬性創建對象

Question

需要幫助解析以下XML。我是Linq to XML的新手。 我想分析在一個單一的對象數組中的所有圖像數據，我似乎沒有找到一種方法，

這裏是一個示例XML，

<Object type="System.Windows.Forms.Form, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="Form1" children="Controls"> 
    <Object type="System.Windows.Forms.PictureBox, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="PictureBox1" children="Controls"> 
     <Property name="TabIndex">0</Property> 
     <Property name="Size">206, 152</Property> 
     <Property name="ImageLocation">C:\Documents and Settings\Administrator\Desktop\logo2w.png</Property> 
     <Property name="Location">41, 68</Property> 
     <Property name="TabStop">False</Property> 
     <Property name="Name">PictureBox1</Property> 
     <Property name="DataBindings"> 
      <Property name="DefaultDataSourceUpdateMode">OnValidation</Property> 
     </Property> 
    </Object> 
    <Object type="System.Windows.Forms.PictureBox, System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" name="PictureBox2" children="Controls"> 
     <Property name="TabIndex">0</Property> 
     <Property name="Size">206, 152</Property> 
     <Property name="ImageLocation">C:\Documents and Settings\Administrator\Desktop\logo2w.png</Property> 
     <Property name="Location">42, 68</Property> 
     <Property name="TabStop">False</Property> 
     <Property name="Name">PictureBox2</Property> 
     <Property name="DataBindings"> 
      <Property name="DefaultDataSourceUpdateMode">OnValidation</Property> 
     </Property> 
    </Object>  
</Object> 

我要訪問的價值PictureObjects[0].Location = 41, 68，PictureObjects[1].Location = 42, 68我可以做嗎？

我看到了幾個樣本，我可以根據節點名稱創建這樣的對象，而不是基於節點屬性值？ C# LINQ with XML, cannot extract multiple fields with same name into object

有人可以指導或讓我知道它是否可行？

你可以用這個啓動，下面的代碼只需選擇的TabIndex和Size屬性，顯然增加其他不會是一個棘手：

XDocument xdoc = XDocument.Load(@"path to a file or use text reader"); 
var tree = xdoc.Descendants("Object").Skip(1).Select(d => 
      new 
      { 
       Type = d.Attribute("type").Value, 
       Properties = d.Descendants("Property") 
      }).ToList(); 

var props = tree.Select(e => 
    new 
    { 
     Type = e.Type, 
     TabIndex = e.Properties 
        .FirstOrDefault(p => p.Attribute("name").Value == "TabIndex") 
        .Value, 
     Size = e.Properties 
       .FirstOrDefault(p => p.Attribute("name").Value == "Size") 
       .Value 
    });
