CommonName,FormalName,TelephoneCode,CountryCode
Argentina,Argentine Republic,54,ARG
Armenia,Republic of Armenia,374,ARM
Australia,Commonwealth of Australia,61,AUS
Austria,Republic of Austria,43,AUT
“Bahamas, The”,Commonwealth of The Bahamas,-241,BHS
Bangladesh,People’s Republic of Bangladesh,880,BGD

The next step is to create a class which has properties with the same name of the column headings found in the csv file.  Below you will find an example of a class which does this:

Finally create an instance of CSVReader and invoke the GetRecords method using the DataRecord class.  Below you will find an example of this:

An completed example can be found below:
