    <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>

с использованием

       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; }
    }
}

}

теперь я могу получить URL-адрес с помощью оператора select и правильно его отобразить, но как мне получить URL-адрес для изображения с size = "cover"

довольно новымПри всем этом пытаться учиться, как я иду один, поэтому любая помощь будет велика: D

спасибо

Answer 1

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