C#秒转换为时分秒（转）

C#将秒数转化为时分秒格式00:00:00
//将秒数转化为时分秒
private string sec_to_hms(long duration)
{
TimeSpan ts = new TimeSpan(0, 0, Convert.ToInt32(duration));
string str = "";
if (ts.Hours > 0)
{
str = String.Format("{0:00}", ts.Hours)+":"+ String.Format("{0:00}", ts.Minutes) + ":" + String.Format("{0:00}", ts.Seconds);
}
if (ts.Hours == 0 && ts.Minutes > 0)
{
str = "00:"+ String.Format("{0:00}", ts.Minutes)+":" + String.Format("{0:00}", ts.Seconds);
}
if (ts.Hours == 0 && ts.Minutes == 0)
{
str = "00:00:" + String.Format("{0:00}",ts.Seconds);
}
return str;
}
结果为：

00:00:10

00:01:10

03:01:10等
