public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();

}
void LongList_SelectionChanged(object sender, SelectionChangedEventArgs e)

{
}
}
}
void MainPage_Loaded(object sender, RoutedEventArgs e)
{

for (int i = 0; i < 10; i++)

}
IEnumerable<mydata> getContent(int k)
{

}
}
public class Group<S, T> : IEnumerable<T>
