✅ Array look if in right order?

I have this array:

int[] numbers = {1, 3, 4, 2, 6};

int[] numbers = {1, 3, 4, 2, 6};

After that array, I have this:

private void label2_Click(object sender, EventArgs e)
        {

            int scorestreet = 0;

            Array.Sort(numbers);

            bool isInSequence = numbers.SequenceEqual(Enumerable.Range(1, numbers.Count()));

            MessageBox.Show(isInSequence.ToString());
        }

private void label2_Click(object sender, EventArgs e)
        {

            int scorestreet = 0;

            Array.Sort(numbers);

            bool isInSequence = numbers.SequenceEqual(Enumerable.Range(1, numbers.Count()));

            MessageBox.Show(isInSequence.ToString());
        }

Currently it looks if it's in the right order '1 2 3 4 5' (It's not at the moment, so it'll return false.)

But how can I make it look if it's in the right order '1 2 3 4'? It keeps returning false because it looks at all numbers in the array, not only the first 4. I tried changing 'numbers.Count()' to 4, and I also tried 'numbers.Count() - 1' but those aren't working.
