Question

how do I format output in seconds:milliseconds format?

TimeSpan start = TimeSpan.Parse(pair.Value[3]);
TimeSpan end = TimeSpan.Parse(pair.Value[4]);
Console.WriteLine(TimeSpan.Compare( start,end));

The code here is printing the difference in seconds. how can i fix it using string.format as i dont know the convention for milliseconds?

Answer 1

You need to look at the difference between the two timespans.

TimeSpan start = new TimeSpan(42); // 42 ticks
TimeSpan end = new TimeSpan(420000000);
TimeSpan diff = end.Subtract(start);
string ms = diff.Milliseconds.ToString();
string sec = ((int)diff.TotalSeconds).ToString();
Console.WriteLine(sec + ":" + ms);
