Hi
you can have sql statement to retrieve member name and age
Select Name, DATEDIFF(MM,dob, GETDATE()) From Member
or
If you wanted to perform through programming
read MemberName and DOB to DataTable and
DataTable tab = new DataTable();
var stateList = from row in tab1.AsEnumerable().AsQueryable()
select new { Name = row["Name"], Age = DateTime.Now.Subtract(DateTime.Parse(row["DOB"].ToString())).TotalDays / 30 };
