Generating a 4–8 digit random number

Question

Random random = new Random();
int password = random.Next(10000);

This generates 2-digit and 3-digit numbers also. How do I generate a 4–8 digit random number in C#?

Answer 1

To cover all your bases (numbers under 1000 such as 0002)

Random RandomPIN = new Random();
var RandomPINResult = RandomPIN.Next(0, 9999).ToString();
RandomPINResult = RandomPINResult.PadLeft(4, '0');

Answer 2

new Random(Guid.NewGuid().GetHashCode()).Next(0, 9999).ToString("D4")
