时间戳 系统时间 互转

1 将系统时间转换成UNIX时间戳



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

DateTime dtNow = DateTime.Parse(DateTime.Now.ToString());

TimeSpan toNow = dtNow.Subtract(dtStart);

string timeStamp = toNow.Ticks.ToString();

timeStamp = timeStamp.Substring(0,timeStamp.Length - 7);



2将UNIX时间戳转换成系统时间



string timeStamp = "1144821796";

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

long lTime = long.Parse(timeStamp + "0000000");

TimeSpan toNow = new TimeSpan(lTime);

DateTime dtResult = dtStart.Add(toNow);
