Question

What is the best way to convert seconds into  Hour Minutes Seconds Milliseconds  time   Let s say I have 80 seconds  are there any specialized classes techniques in  NET that would allow me to convert those 80 seconds into  00h 00m 00s 00ms  format like to DateTime or something

If you know you have a number of seconds  you can create a TimeSpan value by calling TimeSpan FromSeconds     TimeSpan ts   TimeSpan FromSeconds 80     You can then obtain the number of days  hours  minutes  or seconds   Or use one of the ToString overloads to output it in whatever manner you like

The TimeSpan constructor allows you to pass in seconds  Simply declare a variable of type TimeSpan amount of seconds  Ex   TimeSpan span   new TimeSpan 0  0  500   span ToString

Why do people need TimeSpan AND DateTime if we have DateTime AddSeconds     var dt   new DateTime 2015  1  1  AddSeconds totalSeconds     The date is arbitrary  totalSeconds can be greater than 59 and it is a double  Then you can format your time as you want using DateTime ToString     dt ToString  H mm ss      This does not work if totalSeconds  lt  0 or   59   new DateTime 2015  1  1  0  0  totalSeconds
