Converting ADODB to SQLClient.SQLConnection

I have an old VB6 application that was converted to VB.net a couple years ago. The program is very SQL intensive (SQL Server 2005), it currently connects using ADODB.Connection and ADODB.Recordset
I would like to convert it to the new .Net connection SQLClient.SQLConnection  but I would like to avoid modifying every line of code in the application
Is there a class somewhere that I can import that would provide a interface to SQLConnection. For instance instead of declaring my record sets of ADODB.REcordset I could declare them as this class and it would be a front end to the new connection, making modifying my existing RS.MoveNext   RS_TMP.Fields("ContactName").Value etc not required,

If someone could point me in the right direction that would be great
Thanks

I dont see it as possible. This highlights the importance of separating the DAL (Data Access Layer) from everything else because then you need to make changes at fewer places.

I appreciate your comment. Unfortunately I am not the original programmer so now I am left trying to cleanup the lack of forethought.

I think you have the option now to convert the project to not only use the ADO.NET but to use the DAL. Because its not just the variable declarations that need changing, there are loads of other changes to be made as you mentioned.

I left this question open because I did not receive an answer that I thought was worth accepting.
The only answer was its not possible.

I was in fact able to make a class as takes all the same calls as the old OLEDB Record set but connects to the database as the new SQLConnection.  As for existing code all I needed to do was change the recordset declaration from the OLEDB to my new class, no other code changes required.
