XML元素7

Question

大家一直停留在這個有一段時間了，也不太清楚從這裏到

去我一直在使用

 void movie_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e) 
    { 
     if (e.Error != null) 
      return; 
     XElement xmlMovie = XElement.Parse(e.Result); 

     listBox1.ItemsSource = from movie in xmlMovie.Descendants("movies") 
           select new MovieItem 
           { 
            FilmName = movie.Element("movie").Element("alternative_name").Value, 
            overview = movie.Element("movie").Element("overview").Value, 
            rating = movie.Element("movie").Element("rating").Value, 
            filmurl = movie.Element("movie").Element("images").Element("image").Attribute("url").Value 
           }; 


     listBox2.ItemsSource = from movie in xmlMovie.Descendants("movies") 
           // where movie.Element("movie").Element("images").Element("image").Attribute("size").Value == "cover" 
           select new MovieItem 
           { 
            rating = movie.Element("movie").Element("rating").Value 
           }; 

     var urls = xmlMovie 
      .Descendants("image") 
      .Where(x => x.Attribute("size").Value == "cover") 
      .Select(x => x.Attribute("url").Value) 
      .ToArray(); 

    } 

    public class MovieItem 
    { 
     public string FilmName { get; set; } 
     public string overview { get; set; } 
     public string Poster { get; set; } 
     public string rating { get; set; } 
     public string filmurl { get; set; } 
    } 
}

    <overview>Gotham City: dark, dangerous, 'protected' only by a mostly corrupt police department. Despite the best efforts of D.A. Harvey Dent and police commissioner Jim Gordon, the city becomes increasingly unsafe...until a Dark Knight arises. Jack Napier, one-time enforcer for Boss Grissom, horribly disfigured after a firefight in a chemical factory...who, devoid of the last vestiges of sanity, seizes control of Gotham's underworld as the psychotic, unpredictable Clown Prince of Crime...the Joker.</overview>

現在我能夠使用我的選擇語句關閉url並正確顯示它，但是如何獲得url f或與大小=圖像「覆蓋」

在這一切的努力學習，因爲我一個人去很新，所以任何幫助將是巨大的：d

感謝

var urls = xmlMovie 
    .Descendants("image") 
    .Where(x=>x.Attribute("size").Value=="cover") 
    .Select(x=>x.Attribute("url").Value) 
    .ToArray();
