Read a csv file and update sql db

Question

I'm a newbie to C#. I've put together the code below - see two commented lines where the for loop starts. need advise as to the correct approach. you may insert pseudo
code in appropriate places. Thanks in advance.
Below is my code:
public class MailingConfirmationService
        private SqlConnection _con = new SqlConnection(ConfigurationManager.AppSettings.Get("ConnectionString"));
        public void ProcessFilesForMailingConfirmation()
            //Process file(s)
            IResource resourceFile = ResourceFactory.GetResourceFile(ResourceList.FileLocation);
            DirectoryInfo dataFiles = new DirectoryInfo(resourceFile.GetString("filesourcelocation"));
            if (dataFiles.GetFiles().Length > 0)
                log.Info("File Processing started");
                foreach (FileInfo dataFile in dataFiles.GetFiles("*.csv"))
                    log.Info("Processing Data File: " + dataFile.Name);
                    if (dataFile != null && dataFile.Name.Contains("IN"))
                        foreach (string sLine in File.ReadLines(dataFile))                     
                                  _con.Open();
                                cmd.ExecuteNonQuery();
                                _con.Close();

Answer 1

The   foreach (string sLine in File.ReadLines(dataFile))
  should be  foreach (string sLine in File.ReadLines(dataFile.FullName))
its expecting path as param.
