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";}

我就是這樣做的
var?ts?=?new?TimeSpan(DateTime.UtcNow.Ticks?-?dt.Ticks);double?delta?=?Math.Abs(ts.TotalSeconds);if?(delta?<?60){
