You can use a disconnected ADODB.Recordset, if you wish, within 
(ASP).NET - but you haven't provided a good reason for doing so. It 
would be much easier to use ADO.NET to retrieve a DataTable.

However, if you must use ADODB, there's no reason to use late binding. 
You should create a reference to Microsoft ActiveX Data Objects 2.8 
Library. If you then use correctly typed objects, you get feedback via 
intellisense - making it much less likely to make mistakes.
