TimeSpan to integer

I know this has halready had a response marked as the answer, but I was thinking it might be fun to look at it from another viewpoint...


First TimeSpan is represented internally as a long (just get the TimeSpan.Ticks property, and Bob's your uncle), so it's already an integer type.

Second, you could convert it to a decimal, just for the coding exercise:

public static class ExtensionMethods
{
    //-------------------------------------------------------------
    public static decimal ToDecimal(this TimeSpan span)
    {
        decimal spanSecs = (span.Hours * 3600) + (span.Minutes * 60) + span.Seconds;
        decimal spanPart = spanSecs / 86400M;
        decimal result = span.Days + spanPart;
        return result;
    }
    //-------------------------------------------------------------
    public static TimeSpan ToTimeSpan(this decimal value)
    {
        int days = Convert.ToInt32(Math.Ceiling(value));
        value -= days;
        int time = Convert.ToInt32(value * 86400M);
        TimeSpan result = new TimeSpan(1, 0, 0, time, 0);
        return result;
    }
}

Usage would be thus:

TimeSpan span          = new TimeSpan(0,12,0,0,0);
decimal  spanAsDecimal = span.ToDecimal();
TimeSpan span2         = spanAsDecimal.ToTimeSpan();

Useful? Maybe, maybe not. Fun to code? Yep.

Caveat: This doesn't take milliseconds into account, but it would be easy to add.
