CSV Parser, how to auto discover col names & types

I am loading CVS files for data import. The files come from various sources so the header names and location are often changing. I searched and found helpful libs like CsvHelper & FileHelpers

Question: either using FileHelper.net or CsvHelper, how do we extract both the Header names & the Column datatype? so that I can create a drop for each col, to map between .NET type <==> to a SQL type
