How to generate 4 digit numbers randomly?

Question

I am using this piece of code:

byte[] intBytes = new byte[4];

rnd.GetBytes(intBytes);

return Math.Abs(BitConverter.ToInt32(intBytes, 0)) % maxValue + 1;

The above code only generates 3 digits. I would like for it to generate 4 digits?

I have changed the byte[4] to byte[5] but still only generates 3 digits?

What about?

Random random = new Random();
int randomNumber = random.Next(1000, 10000);
