leer base de datos de Visual FoxPro (dbf).

Utilzando el OleDbProvider apropiado, yo leo DBFs con el siguiente proveedor,
te pongo un ejemplo, que lee el archivo FMOV en el directorio \GFAC\DATOS00:

namespace DBFs
{

using System;
using System.Data;
using System.Data.OleDb;

public class OleDbReader
{
public static void Main()
{
OleDbReader miReader = new OleDbReader();
miReader.Run();
}

public void Run()
{
OleDbDataReader miDataReader = null;


OleDbConnection mySqlConnection = new
OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=c:\\gFac\\Datos00;Extended Properties=dBASE IV;User
ID=Admin;Password=");
OleDbCommand mySqlCommand = new OleDbCommand("SELECT factura, fecha " +
"FROM fmov WHERE tipo = '4'
ORDER BY fecha", mySqlConnection);
try
{
mySqlConnection.Open();
myDataReader = mySqlCommand.ExecuteReader();

while (myDataReader.Read())
{
Console.Write(myDataReader[0].ToString() + "-");
Console.WriteLine(myDataReader[1].ToString());
}
}
catch(Exception e)
{
Console.WriteLine(e.ToString());
}
finally
{
if (myDataReader != null)
myDataReader.Close();

if (mySqlConnection.State == ConnectionState.Open)
mySqlConnection.Close();
}
}
}

}
