I've switched your for loop with a do...while loop and set the stopping condition on the list count being smaller then 6. This might not be the best solution but it's the closest to your original code.

        int numbers = rand.Next(1,49);
        if(!listNumbers.Contains(number)) {
            listNumbers.Add(numbers);
        }
    } while (listNumbers.Count < 6)
