Create a year dropdownlist that with dynamically created year values

Using vb.net/asp.net 2005
I have a Year dropdownlist that I want to have the listItems created dynamically with these conditions:
1.  the oldest year selection will be "2009"
2.  all years including "2009" and the current year will be included in the listitems.
It's obvious now (at this date) that 2009 and 2010 will be the 2 current listitems, however I want this dropdownlist to automatically add all subsequent years in coming years so that there will not be the need to add a new year listitem each year.
thanks
MC
