How to generate a random 10 digit number in C#?

Question

I\'m using C# and I need to generate a random 10 digit number. So far, I\'ve only had luck finding examples indicating min maximum value. How would i go about generating a r

Answer 1

To get the any digit number without any loop, use Random.Next with the appropriate limits [100...00, 9999...99].

private static readonly Random _rdm = new Random();
private string PinGenerator(int digits)
{
   if (digits <= 1) return "";

   var _min = (int)Math.Pow(10, digits - 1);
   var _max = (int)Math.Pow(10, digits) - 1;
   return _rdm.Next(_min, _max).ToString();
}

This function calculated the lower and the upper bounds of the nth digits number.

To generate the 10 digit number use it like this:

PinGenerator(10)
