Using OLE to connect to a text file

This code demonstrates how to use the OLE database driver in order to connect to a text file.

using System;
using System.Data;
using System.Data.OleDb;
using System.IO;
using System.Text;

namespace OLEDBCSVDataSource
{
  class CSVDataExample
  {
    private const string OLE_CONN_STRING = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};" + 
            "Extended Properties='text;HDR=Yes;FMT=Delimited'";

    [STAThread]
    static void Main( string[] args )
    {

      string sFileName   = "CSVData.txt";
      string sExecPath   = Path.GetDirectoryName( System.Reflection.Assembly.GetExecutingAssembly().Location );
      string sDataSource = Path.Combine( sExecPath, sFileName );
      string sConn       = String.Format( OLE_CONN_STRING, sExecPath );

      using ( OleDbConnection conn = new OleDbConnection( sConn ) )
      {
        OleDbCommand cmdSelect = new OleDbCommand( "SELECT * FROM " + sFileName, conn );
        conn.Open();
        OleDbDataReader reader = cmdSelect.ExecuteReader();
         while( reader.Read() )
         {
          int iFieldCount = reader.FieldCount;
          StringBuilder sb = new StringBuilder();
          for( int i = 0; i < iFieldCount; i++ )
          {
            sb.Append( reader.GetValue( i ).ToString() );
             sb.Append( "\t" );
          }
          Console.WriteLine( sb.ToString() );
        }
        reader.Close();
      }
      Console.ReadLine();
    }
  }
