NoOfValues= 10
Start Time= 11/18/2013 4:29:50 PM End Time= 11/18/2013 4:30:00 PM

推荐答案
Dim myDate1 As DateTime = new DateTime(2013, 11, 18, 4, 29, 38);
Dim myDate2 As DateTime = new DateTime(2013, 11, 18, 4, 29, 49);
TimeSpan ts = myDate2 - myDate1;
long elapsedInMilliseconds = ts.Elapsed;
float valueInSeconds = (float)elapsedInMilliseconds / 1000f;
int value = Math.Floor(valueInSeconds);
