C#獲取時間戳

        /// <summary>
        /// 獲取當前時間戳

        /// <param name="flg">10位的或者13位的時間戳</param>

        private long GetTimeStamp(int flg)
        {
            long time = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000;
            switch (flg)
            {
                case 10:
                    time = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000;
                    break;
                case 13:
                    DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1, 0, 0, 0, 0));
                    time = (DateTime.Now.Ticks - startTime.Ticks) / 10000;
                    break;
            }
            return time;
        }

根據自己的情況使用；

var time1 = GetTimeStamp(10);//1570872398
var time2 = GetTimeStamp(13);//1570872398027
