计算文章发表时间段

在论坛，微博里面经常会看到贴子，微博的发布时间显示的是，几天以前，几个小时以前，几分钟以前，几秒以前等统计

下面是一个计算距离发表时刻时间段的方法

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

public  String CalculateTime_1 (DateTime date ) { TimeSpan now  =  new TimeSpan (DateTime . Now . Ticks ) ; TimeSpan cur  =  new TimeSpan (date . Ticks ) ; TimeSpan diff  = now . Subtract (cur ) ; if  (diff . TotalHours  { return  "Today" ; } else  if  (diff . TotalHours  { return  "Yesterday" ; } else  if  (diff . TotalDays  { return  String . Format ( "{0} days ago", diff . Days ) ; } else { return  String . Format ( "{0} months ago",  (diff . Days  /  30 ) ) ; } }

public  String CalculateTime_2 (DateTime date ) { TimeSpan now  =  new TimeSpan (DateTime . Now . Ticks ) ; TimeSpan cur  =  new TimeSpan (date . Ticks ) ; TimeSpan diff  = now . Subtract (cur ) ; if  (diff . TotalSeconds  ==  0 ) { return  "Just now" ; } if  (diff . Days  ==  0 ) { if  (diff . Hours  ==  0 ) { if  (diff . Minutes  ==  0 ) { return  String . Format ( "{0} second{1} ago", diff . Seconds, diff . Seconds  &gt ;  1  ?  "s"  :  String . Empty ) ; } else { return  String . Format ( "{0} minute{1} ago", diff . Minutes, diff . Minutes  &gt ;  1  ?  "s"  :  String . Empty ) ; } } else { return  String . Format ( "{0} hour{1} ago", diff . Hours, diff . Hours  &gt ;  1  ?  "s"  :  String .
