DateTime st = DateTime.Now;

DateTime ed = DateTime.Now;

TimeSpan ts = ed.Subtract(st);

string output = String.Format("{0:00}:{1:00}:{2:00}", ts.TotalHours, ts.Minutes, ts.Seconds);

 

//時間與字串之間的轉換

//時間轉字串

string datestring = DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss ffff")

string datestring = DateTime.Now.ToString("s", System.Globalization.DateTimeFormatInfo.InvariantInfo)

"s" 代表Sortable格式 "yyyy/MM/ddTHH:mm:ss"



//字串轉時間

DateTime st = DateTime.Parse(datestring);
