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?

cmd.CommandType = CommandType.StroredProcedure<br />
cmd.CommandText = "sp_someStoredprocedure";<br />
cmd.Parameters.Add(new SqlParameter("@myDate",SqlDbType.Date));<br />
cmd.Parameters["@myDate"].Value = myDateInstance;
