Имеется файл 1.gpx. Пишу следующий код:

internal class Program
{
private static void Main(string[] args)
{
XElement root = XElement.Load("C:/1.gpx");
IEnumerable<TrackInfo> tracks = from e in root.Elements("trk")
select new TrackInfo
{
Name = (string)e.Element("name"),
};
foreach (TrackInfo trackInfo in tracks)
{
Console.WriteLine(trackInfo.Name);
Console.WriteLine();
}
Console.ReadLine();
}
}
Код должен вывести два имени, но ничего не выводит. В чем дело? Пример простейший, полностью повторяет один из примеров MSDN.
