const int SECOND = 1;const int MINUTE = 60 * SECOND;const int HOUR = 60 * MINUTE;const int DAY = 24 * HOUR;const int MONTH = 30 * DAY; var ts = new TimeSpan(DateTime.UtcNow.Ticks - yourDate.Ticks);double delta = Math.Abs(ts.TotalSeconds);if (delta < 1 * MINUTE) return ts.Seconds == 1 ? "one second ago" : ts.Seconds + " seconds ago";if (delta < 2 * MINUTE) return "a minute ago";if (delta < 45 * MINUTE) return ts.Minutes + " minutes ago";if (delta < 90 * MINUTE) return "an hour ago";if (delta < 24 * HOUR) return ts.Hours + " hours ago";if (delta < 48 * HOUR) return "yesterday";if (delta < 30 * DAY) return ts.Days + " days ago";if (delta < 12 * MONTH){ int months = Convert.ToInt32(Math.Floor((double)ts.Days / 30)); return months <= 1 ? "one month ago" : months + " months ago";}else{ int years = Convert.ToInt32(Math.Floor((double)ts.Days / 365)); return years <= 1 ? "one year ago" : years + " years ago";}

我就是这样做的
var ts = new TimeSpan(DateTime.UtcNow.Ticks - dt.Ticks);double delta = Math.Abs(ts.TotalSeconds);if (delta < 60){ return ts.Seconds == 1 ? "one second ago" : ts.Seconds + " seconds ago";}if (delta < 120){ return "a minute ago";}if (delta < 2700) // 45 * 60{ return ts.Minutes + " minutes ago";}if (delta < 5400) // 90 * 60{ return "an hour ago";}if (delta < 86400) // 24 * 60 * 60{ return ts.Hours + " hours ago";}if (delta < 172800) // 48 * 60 * 60{ return "yesterday";}if (delta < 2592000) // 30 * 24 * 60 * 60{ return ts.Days + " days ago";}if (delta < 31104000) // 12 * 30 * 24 * 60 * 60{ int months = Convert.ToInt32(Math.Floor((double)ts.Days / 30)); return months <= 1 ? "one month ago" : months + " months ago";}int years = Convert.ToInt32(Math.Floor((double)ts.Days / 365)); return years <= 1 ? "one year ago" : years + " years ago";
