Export Access table to Excel

this is what i have so far, whats is when i click y button , the report goes over to excel with out the data, It only has the headers thats in the report, Im not understanding why .
I dont know if its the binding source or not. but its weird.

public void Export()
{  
        LocalReport lr = new LocalReport();
            BindingSource bs = new BindingSource();
            DatatabeDataSet test = new CLUDatatabeDataSet OpDatabaseDataSet();
            bs.DataSource = test;
            bs.DataMember = "Datatable";

            
            // the ReportDataSource.Name must be the name of the class that is the DataSource
            lr.DataSources.Add(new ReportDataSource("CLU_OpDatabaseDataSet_Datatable", bs));
            // the ReportEmbeddedResource is the same as what is in the ReportViewer properties
            lr.ReportEmbeddedResource = "EventLogSam.DatatableReport.rdlc";
            string deviceInfo = "" +
                 "false" +
                 "false" +
                 "false" +
                 "";
            Warning[] warnings;
            m_streams = new List();

            try
            {
                lr.Render("Excel", deviceInfo, CreateStream, out warnings);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
                return;
            }
            foreach (Stream stream in m_streams)
                stream.Position = 0;
        }

        private Stream CreateStream(string name, string fileNameExtension,
            Encoding encoding, string mimeType, bool willSeek)
        {
            Stream stream = new FileStream(sExportPath, FileMode.Create);
            m_streams.Add(stream);
            return stream;
        }

I know that , but how do I get to that object through c# code,
