How do I calculate due date with whole months?

I'm trying to calculate the due date of an invoice, and I have a date of invoice, days to due date (100) and I need to calculate due date with whole months:

For example:
if date of invoice = 07/05/2009 and days of due date = 120, then the due date calculated = 07/09/2009 (4 months exactly -whole months-).
My code:
 
DateTime invoiceDate=System.DateTime.Now();
int numberOfDays=100;
int numberOfMonths;
int restOfNumberOfDays;
Date dueDate;
 
if(wholeMonths)
{
    numberOfMonths = numberOfDays % 30;
    dueDate = dt.AddMonths(numberOfMonths);
    restOfNumberOfDays = numberOfDays - (numberOfMonths * 30);
    dueDate = dueDate.AddDays(restOfNumberOfDays);
}
 
This code would be correct if the month had 30 days long.
