Question

I have a case where I have to generate transaction number based on specific pattern
The pattern is following:

MA 0000000/dd/mm/YYYY/00000

where first zeros are random numbers then current date and last zeros should be incremental

(00001… 00010… 00100… 00578)

Could you please provide correct way to implement this case.

Answer 1

public static class Generator
{
    static int current = 0;
    static Random rand = new Random();

    public static string NextId()
    {
        return string.Format("MA {0:0000000}/{1}/{2:00000}", 
          rand.Next() % 100000,
          DateTime.Now.ToString("dd/MM/yyyy"),
          current++ );
    }
}
