Convert the date and time to make it display more friendly and convert the date and time

Sometimes we want to display the time and date in a more friendly way, such as a few seconds ago, a few minutes ago, a few hours ago ......

 

Here:
1. Check whether the format of the input date is correct.
2. Use TimeSpan to calculate the interval between date and time, and then convert it to seconds, minutes, and so on.
3. Convert the data to seconds, minutes, hours, and days.

 

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(LetTimeSay("2015-3-27"));
            Console.ReadKey();
        }
        static string LetTimeSay(string str)
        {
            DateTime t;
            if (DateTime.TryParse(str, out t))
            {
// Calculation Interval
                TimeSpan ts = DateTime.Now - t;
// Convert to minutes
                double m = ts.TotalMinutes;
                if (m < 1)
                {
                    double s = m*60;
Return (int) Math. Floor (s) + "seconds ago ";
                }
                else if (m < 60)
                {
Return (int) Math. Floor (m) + "Minutes Ago ";
                }
                else if (m < 60 * 24)
                {
                    double h = m/60;
Return (int) Math. Floor (h) + "Hours Ago ";
                }
                else
                {
                    double d = m/(60*24);
Return (int) Math. Floor (d) + "Days Ago ";
                }
            }
            else
            {
Return "the date format does not match ";
            }
        }
    }
