分享在C#中时间戳是怎么转换的？

时间戳转DateTime

timestamp为10位秒级* 10000000，若为13位毫秒级*10000。

private DateTime TimestampToDateTime(long timestamp)

{

DateTime dateTimeStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970,1,1));

long lTime = timestamp * 10000000;

TimeSpan NowTimeSpan = new TimeSpan(lTime);

DateTime resultDateTime = dateTimeStart.Add(NowTimeSpan);

return resultDateTime;

}

DateTime转时间戳

秒级

private int DateTimetoTimestamp(DateTime time)
{
DateTime startDateTime = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(197, 1, 1));
return Convert.ToInt32((time - startDateTime).TotalSeconds);

}
