datetime weekdays

[Brad Quinn]

I tried posting this on Friday, but I guess the servers were down.

public static DateTime AddWeekdays( DateTime start, int days )
{
if ( start.DayOfWeek == DayOfWeek.Saturday || start.DayOfWeek ==
DayOfWeek.Sunday ) {
throw new ArgumentException( "start must be a weekday" );
}
int remainder = days % 5;
int weekendDays = ( days / 5 ) * 2;

DateTime end = start.AddDays( remainder );

if ( end.DayOfWeek == DayOfWeek.Saturday ) {
// add two days for landing on saturday
end = end.AddDays( 2 );
}
else if ( end.DayOfWeek < start.DayOfWeek ) {
// add two days for rounding the weekend
end = end.AddDays( 2 );
}
// add the remaining days
return end.AddDays( days + weekendDays - remainder );
}
