public class Program
{
    public static void Main()
    {
        List<int> lst = new List<int>() { 1, 2, 3, 0, 4, 5, 6, 7, 0, 8, 9, 10 };
        var list_of_lists_by_zero = lst.Aggregate(new List<List<int>>{new List<int>()},
                                   (list, value) => {
                                       list.Last().Add(value);
                                       if (value == 0) list.Add(new List<int>());
                                       return list;
                                   });
 
        foreach (List<int> subList in list_of_lists_by_zero) {
            foreach (int elements in subList) {
                Console.WriteLine(elements);
            }
            Console.WriteLine();
