Your code would not even compile, so how can you say it is slow:

C#
List<Number> numbers = new List<Number>() { 2, 3, 4, 5, 6, ... , 2000000 };

for (int i = 0; i < numbers.Count - 1; i++)
   if (numbers[i].IsPrime)
      for (int j = i + 1; j < numbers.Count - 1; j++)
              if (numbers[j].Value % numbers[i].Value == 0)
                     numbers[j].IsPrime = false;
