如何在C＃Windows Phone中读取元素xml的属性？

Question

我开发一个应用程序，可以阅读RSS，我设置这样的

public class Item 
{ 
    [XmlElement("title")] 
    public string title { get; set; } 
    [XmlElement("description")] 
    public string description { get; set; } 
    [XmlElement("enclosure")] 
    public string enclosure { get; set; } 
    [XmlElement("pubDate")] 
    public string pubDate { get; set; } 
    [XmlElement("link")] 
    public string link { get; set; } 
} 

Howerver一类，该项目将返回

<item> 
<title> 
Colombia 2-1 Paraguay: James Rodriguez and Carlos Bacca score as Jose Pekerman's side reach Copa America quarter-finals 
</title> 
<link>

</link> 
<description> 
James Rodriguez scored a goal and set up another as Colombia became the first team to clinch a place in the Copa America quarter-finals. The Real Madrid provided the assist for Carlos Bacca's opener. 
</description> 
<enclosure url="http://i.dailymail.co.uk/i/pix/2016/06/08/05/350A4D8200000578-0-image-a-63_1465360921756.jpg" type="image/jpeg" length="84507" />

</guid> 
</item> 

因此，它是明确表示，“圈地”元素返回空字符串，所以如何通过给出像上面类的注释来读取这个“enclosure”标签的“url”属性，请帮助我！

你必须编写单独的类外壳

 public class Item 
     { 
      [XmlElement("title")] 
      public string title { get; set; } 
      [XmlElement("description")] 
      public string description { get; set; } 
      [XmlElement("enclosure")] 
      public Enclosure enclosure { get; set; } 
      [XmlElement("pubDate")] 
      public string pubDate { get; set; } 
      [XmlElement("link")] 
      public string link { get; set; } 
     } 

    public class Enclosure 
    { 
     [XmlAttribute("url")] 
     public string Url { get; set; } 
    //if enclosure has any child elements it comes under XmlElement like this 
    // [XmlElement("enclosurechildelement")] 
    // public string enclosurechildelement { get; set; } 


    }
