【轉】UNIX時間戳與.net日期類的轉換

1 將系統時間轉換成UNIX時間戳
  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將UNIX時間戳轉換成系統時間
  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);

 

 

//===================================

//DateTime轉變為UNIX時間，直接轉換，不改變時區
DateTime dtStart = new DateTime(1970, 1, 1, 0, 0, 0);
TimeSpan toNow = dt.Subtract(dtStart);
int timeStamp = (int)(toNow.Ticks/10000000);

//===================================

短短幾行代碼,卻花了我幾個小時,就因為時區的問題,@_@
