Newbie - delete item from collection

I have defined a and populated a generic list with 3rd party software.
After it is created, I need to remove all items with an errorcode
value > 90.

Is this supposed to work?

         for (int idx = 0; idx < _someList.Count; idx++)
         {
            if (_someList[idx].ErrorCode > 90)
               _someList.RemoveAt(idx);
         }

After I "removed" items with ErrorCode> 90, the list still contained some items with ErrorCodes over 90.

Or should I create a new list and add items to it from the old list with ErrorCodes <=90?

Thanks, Lars
