如何将datetime转换为facebook格式？

Question

我想知道是否有一个将时间从那种格式{3/16/2014 7:07:25 AM}转换为facebook格式，就像一小时前一样等我正在使用windows phone 8应用程序

除了搜索库之外，自己编写其中一个函数并不是很难。这是我过去使用过的东西：

public static string ConvertToFacebookLikeTime(DateTime value)
        {
            const int SECOND = 1;
            const int MINUTE = 60 * SECOND;
            const int HOUR = 60 * MINUTE;
            const int DAY = 24 * HOUR;
            const int MONTH = 30 * DAY;

            TimeSpan ts = DateTime.Now - value;
            double delta = ts.TotalSeconds;

            if (delta < 0)
            {
                return "Right Now";
            }
            if (delta < 1 * MINUTE)
            {
                //return ts.Seconds == 1 ? "one second ago" : ts.Seconds + " seconds ago";
                return "A Few 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 ? "A Month Ago" : months + "Months Ago";
            }
            else
            {
                int years = Convert.ToInt32(Math.Floor((double)ts.Days / 365));
                return years <= 1 ? "A Year Ago" : years + " Years Ago";
            }
        }
