c# - How can I select the year in each row -

i trying list of dates of year of manufacture determining age of vehicles. column looks this:

and code looks this

 partial void reports_initializedataworkspace(list<idataservice> savechangesto) {          // year of manufacture         var yom = insurancequotations.selecteditem.myear;         var bday = convert.todatetime(yom);          datetime today = datetime.today;         int age = today.year - bday.year;         if (bday > today.addyears(-age)) age--;          age = convert.tostring(age);      } 

i can select fist date in column. how loop through dates in column?

you can loop through insurance quotes:

foreach (insuarancequote item in insurancequotes) {     var yom = item.myear;     .... } 

note: i'm making presumptions here. 1 grid of insurance quotes of type insurancequote , 2 data collection on screen called insurancequotes.
