很好地显示时间跨度

Question

请原谅粗略的代码,我试图以秒为单位显示视频的持续时间.我有一个下面但它没有正常工作.

我希望它能很好地显示 - 即应该显示9m:59s而不是09m:59s.

如果小时为零则不显示小时数,如果小时数为零则不显示分钟数.

public static string GetTimeSpan(int secs)
{
    TimeSpan t = TimeSpan.FromSeconds(secs);

    string answer;
    if (secs < 60)
    {
        answer = string.Format("{0:D2}s", t.Seconds);
    }
    else if (secs < 600)//tenmins
    {
        answer = string.Format("{0:m}m:{1:D2}s", t.Minutes, t.Seconds);

    }
    else if (secs < 3600)//hour
    {
        answer = string.Format("{0:mm}m:{1:D2}s", t.Minutes, t.Seconds);
    }
    else
    {
        answer = string.Format("{0:h}h:{1:D2}m:{2:D2}s",
                                    t.Hours,
                                    t.Minutes,
                                    t.Seconds);
    }

    return answer;
}

就像是:

public static string PrintTimeSpan(int secs)
{
   TimeSpan t = TimeSpan.FromSeconds(secs);
   string answer;
   if (t.TotalMinutes < 1.0)
   {
     answer = String.Format("{0}s", t.Seconds);
   }
   else if (t.TotalHours < 1.0)
   {
     answer = String.Format("{0}m:{1:D2}s", t.Minutes, t.Seconds);
   }
   else // more than 1 hour
   {
     answer = String.Format("{0}h:{1:D2}m:{2:D2}s", (int)t.TotalHours, t.Minutes, t.Seconds);
   }

   return answer;
}
