I'm trying to make a dynamic array in C# but I get an annoying error message. Here's my code:

    private void Form1_Load(object sender, EventArgs e)
    {
        int[] dataArray;
        Random random = new Random();
        for (int i = 0; i < random.Next(1, 10); i++)
        {
            dataArray[i] = random.Next(1, 1000);
        }
    }

And the error:

Use of unassigned local variable 'dataArray'

This is just baffling my mind. I came from VB, so please me gentle, lol.

Cheers.
