Question

I may be being really stupid here, but my brain’s gone blank.

I’ve got a slider bar (which uses Int32 values) but I want to use it to select a position in a music song (mm.ss)

I also want to output the value that the slider is displaying in to a label above it, so it’s easier to see what the slider is set to.

Anyone have any suggestions?

I thought of trying to convert the int value in to a decimal then dividing by 60.

I’m doing this in C# by the way.

Answer 1

What does the int value represent? If it’s the number of seconds through the song, you should use:

TimeSpan time = TimeSpan.FromSeconds(seconds);
string text = time.ToString(@"mm\.ss");

Using a decimal would be a really bad idea – a format with a number of seconds isn’t the same as a fractional number of minutes. For example, 10.50 minutes as a fractional number of minutes is 10 minutes and 30 seconds, not 10 minutes and 50 seconds, which is what you want as far as I can tell.

TimeSpan is the natural way of representing a time duration in .NET… which is why that’s the type which supports formatting in minutes and seconds.
