C#中，DateTime與TimeStamp互轉

直接看CODE~

DateTime 轉 TimeStamp:

public static double DateTimeConvertToTimeStamp(DateTime Date)
{
    return (Date.ToUniversalTime() - new DateTime(1970, 1, 1, 0, 0, 0) ).TotalSeconds;
}

TimeStamp 轉 DateTime:

public static DateTime TimeStampConvertToDateTime(long TimeStamp)
{
    return (new DateTime(1970, 1, 1, 0, 0, 0)).AddSeconds(TimeStamp);
}
