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);
}
以上就是分享在c#中时间戳是怎么转换的？的详细内容。
