给定特定DateTime值,如何显示相对时间,例如:
DateTime
杰夫,您的代码不错,但可以使用常量使其更清晰(如代码完成中所建议)。
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"; }
