{
    time = time.AddSeconds(1);
    return $"{time.Year}{time.Month:00}{time.Day}{time.Hour}{time.Minute}{time.Second:00}".Substring(2); 
}

DateTime seed = DateTime.ParseExact($"{20}170902145914","YYYYmmddHHmmss",CultureInfo.CurrentCulture);

how can I do this?

Answer 1

Case matters, lower case for year, upper case M is month, lower case m is minute. upper case H is 24hour hour format.

DateTime seed = DateTime.ParseExact($"20170902145914", "yyyyMMddHHmmss", System.Globalization.CultureInfo.CurrentCulture);
