public static string GetTimeStamp()

  TimeSpan ts = DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0);

} 

// 时间戳转为C#格式时间
private DateTime StampToDateTime(string timeStamp)

}
// DateTime时间格式转换为Unix时间戳格式
private int DateTimeToStamp(System.DateTime time)
{
  System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1));
  return (int)(time - startTime).TotalSeconds;
