How to compare two DateTime to seconds?

Answer 1

var date1 = DateTime.Now; var date2 = new DateTime (1992, 6, 6);  var seconds = (date1 - date2).TotalSeconds; 

Answer 2

Do you mean comparing two DateTime values down to the second? If so, you might want something like:

private static DateTime RoundToSecond(DateTime dt) {     return new DateTime(dt.Year, dt.Month, dt.Day,                         dt.Hour, dt.Minute, dt.Second); }  ...  if (RoundToSecond(dt1) == RoundToSecond(dt2)) {     ... } 

Alternatively, to find out whether the two DateTimes are within a second of each other:

if (Math.Abs((dt1 - dt2).TotalSeconds) <= 1) 

If neither of these help, please give more detail in the question.
