miguel,I dont think we need hashtables here.
codemonkeys,I dont know how you work with your SP but its better to know
DataRow object has a property called ItemArray,it hold all the fields in your
row as an
object array...
its easier to work with this,then you can join this array to your arraylist object like below...
Code:
yourArrayList.AddRange(currentDataRow.ItemArray);
now every item in your arraylist has own
type i.e,
varchar(sql)<------>string(.NET)
HtH.
