ADO vs ADO .NET and Data Transfer

Question

Hello, I am looking for the fastest method of data transfer using C#. I want to extract a large amount of data from a table using a make table query to create a local table on a user machine. I am currently using ADO and the "firehose cursor" (forward looking, read only). I was just wondering if there is a faster way to accomplish this. I am also doing something similar in VB6 and was wondering if I would see a noticeable perfomance boost if I upgraded the application to C#. Any thoughts would be great. Thanks
