.Net时间戳转换
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);
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);

//查询操作
SELECT
