The problem with the above code is it consumes too much memory

such a way that I can get the progress of the reading?

Do it the old way, open the file, create a byte array and read a section at a time, but you'll need to do it on a thread or use Application.DoEvents for your UI to update during the process.

is there a better way of sending sql this dateTime?

GC will maintain a separate queue for items that need finalization. So you should implement the Dispose() pattern and clean all your resources. Also call GC.SuppressFinalize() from dispose which will suppress the finalization.
