ADO .NET and Excel in C#

I'm having trouble loading Excel data into my application. Can anyone tell me what's wrong with the following method?

My connectionString is:

Code:

---

private static string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;
                                          Data Source=C:\RD.xls;
                                          Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";";

---

Code:

---

        private void ReadExcelData()
        {
            using (OleDbConnection connection = new OleDbConnection(connectionString))
            {
                using (OleDbCommand command = new OleDbCommand("SELECT * FROM [Questions$]"))
                {
                    connection.Open();
                    using (OleDbDataReader reader = command.ExecuteReader())
                    {
                        while (reader.Read())
                        {
                            Console.WriteLine(reader[0].ToString());
                        }
                    }
                }
            }
        }

I've never use ado with Excel but with Access plenty of times, which I imagine is similar. Anyway, [removed], (though I am fairly new to c# ) but anyway here is a good example to look at check this out, http://blog.lab49.com/?p=196
