.NET Date Compare: Count the amount of working days since a date?

Question

What\'s the easiest way to compute the amount of working days since a date? VB.NET preferred, but C# is okay.

And by \"working days\", I mean all days excluding Satu

Answer 1

The easiest way is probably something like

DateTime start = new DateTime(2008, 10, 3);
DateTime end = new DateTime(2008, 12, 31);
int workingDays = 0;
while( start < end ) {
  if( start.DayOfWeek != DayOfWeek.Saturday
   && start.DayOfWeek != DayOfWeek.Sunday ) {
      workingDays++;
  }
  start = start.AddDays(1);
}

It may not be the most efficient but it does allow for the easy checking of a list of holidays.
