时分秒

public string FormatTime(int totalSeconds)
        {
            int hours = totalSeconds / 3600;
            string hh = hours < 10 ? "0" + hours : hours.ToString();
            int minutes = (totalSeconds - hours * 3600) / 60;
            string mm = minutes < 10f ? "0" + minutes : minutes.ToString();
            int seconds = totalSeconds - hours * 3600 - minutes * 60;
            string ss = seconds < 10 ? "0" + seconds : seconds.ToString();
            return string.Format("{0}:{1}:{2}", hh, mm, ss);
        }

分秒显示

 public string FormatTwoTime(int totalSeconds)
    {
        int minutes = totalSeconds / 60;
        string mm = minutes < 10f ? "0" + minutes : minutes.ToString();
        int seconds = (totalSeconds - (minutes * 60));
        string ss = seconds < 10 ? "0" + seconds : seconds.ToString();
        return string.Format("{0}:{1}", mm, ss);
    }

天显示

public string FormatDayTime(int totalSeconds)
{
    int days = (totalSeconds / 3600) / 24;
    string dd = days < 10 ? "0" + days : days.ToString();
    int hours = (totalSeconds / 3600) - (days * 24);
    string hh = hours < 10 ? "0" + hours : hours.ToString();
    int minutes = (totalSeconds - (hours * 3600) - (days * 86400)) / 60;
    string mm = minutes < 10f ? "0" + minutes : minutes.ToString();
    int seconds = totalSeconds - (hours * 3600) - (minutes * 60) - (days * 86400);
    string ss = seconds < 10 ? "0" + seconds : seconds.ToString();
    return string.Format("{0}:{1}:{2}:{3}", dd, hh, mm, ss);
