Generate a "change every hour" user name

In an ASP. NET project, want to leave a Super admin account.

If the user name of this super Administrator is fixed (for example, administrator), it is unsafe, so you want to generate a long string user name in this way, and change it once per hour.

year +superadmin + Total days + hour à MD5 encryption. Therefore, the user name changes every hour.

Using system;using system.text;using system.security.cryptography;namespace cki. jsonserver.models{    public class superadministratorhelper     {        public static string getname ()          {             int year = DateTime.Now.Year;             int month = DateTime.Now.Month;             int day = DateTime.Now.Day;             int hour = DateTime.Now.Hour;             int sumdays = getdayofyear (month)  + day;             if  (month > 2)              {                 if  (year % 4 == 0)  &&  (year % 100 !=  0)  | |  year % 400 == 0)                  {                      SumDays++;                  }             }             string  sa = year +  "Superadmin"  + sumdays.tostring ("#000")  + hour.
