Question

I\'m using the following query to get the next month.

int theMonth = ((System.DateTime)periodStartDate).Month+1;

But if the periodstartDate

Answer 1

The expression ((System.DateTime)periodStartDate).Month+1 doesn't throw an error if the month is December - it just returns 13. I suspect you're doing this:

var nextMonth = new DateTime(periodStartDate.Year, periodStartDate.Month + 1, 1);

That would throw an error.

Try this instead:

var nextMonth = new DateTime(periodStartDate.Year, periodStartDate.Month, 1)
    .AddMonths(1);
