UNIX时间戳与.net日期类的转换

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);

短短几行代码,却花了我几个小时,就因为时区的问题,@_@
