时间转换的方法:
public string get_time(int duration)
{
TimeSpan ts = new TimeSpan(0, 0, Convert.ToInt32(duration));
string str = "";
if (ts.Hours > 0)
{
str = ts.Hours.ToString() + "小时 " + ts.Minutes.ToString() + "分钟 " + ts.Seconds + "秒";
}
if (ts.Hours == 0 && ts.Minutes > 0)
{
str = ts.Minutes.ToString() + "分钟 " + ts.Seconds + "秒";
}
if (ts.Hours == 0 && ts.Minutes == 0)
{
str = ts.Seconds + "秒";
}
return str;
}
