WPF Application using Access Database

Hi, I'm trying to get some data from an Access database to populate a chart.

I have the data but I'm not sure how to loop through it.

these two values are underlined and it says - The name 'data' does not exist in the current conext

data.ProductName;

data.UnitPrice;

        private void creatChart()
        {
            Chart chart = new Chart();
            chart.Width = 400;
            chart.Height = 300;

            string myConnStr = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\\WPFtoSQL\\App_Data\\Northwind.mdb; User Id=admin; Password=";

            OleDbConnection myConn= new OleDbConnection (myConnStr);

            myConn.Open();
            
            string myQuery = " SELECT * From Products";

            OleDbCommand cmd = new OleDbCommand(myQuery, myConn);

            OleDbDataAdapter da = new OleDbDataAdapter(cmd);

            DataTable dt = new DataTable();
            da.Fill(dt);

            DataSet dataset = new DataSet();

            da.SelectCommand = cmd;
            
            DataSeries ds = new DataSeries();

            foreach (DataRow dataRow in dt.Rows) 
            {
                DataPoint dp = new DataPoint();
                dp.AxisXLabel = data.ProductName;
                dp.YValue = Convert.ToDouble(data.UnitPrice);
                ds.DataPoints.Add(dp);
            }

            chart.Series.Add(ds);

            LayoutRoot.Children.Add(chart);
        }

Thanks v much
