I want to Copy Data from Access database File to Excel worksheet. I use OLEDBConnection but I don't know how to copy all data from Access table to paste to cells A2 on excel.

My table's name is Beam Forces, It has 10 columns: Story,Beam, CaseCombo, Station, P, V2, V3, T, M2, M3.

I do not know where it is wrong. Here is my code:

private void btnInput_Click(object sender, RibbonControlEventArgs e)
       {
           OpenFileDialog MDB = new OpenFileDialog();
           string sFile;
           MDB.Filter = "Access files|*.mdb";
           MDB.AddExtension = true;
           MDB.CheckPathExists = true;
           MDB.Title = "Choose Your Input File";


           if (MDB.ShowDialog() == DialogResult.OK)
           {
               sFile = MDB.FileName;
               //MessageBox.Show(sFile);

               try
               {
                   OleDbConnection MyConnection  = new OleDbConnection();
                   OleDbCommand MyCommand = new OleDbCommand();
                   MyConnection = new  OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + sFile);
                   MyConnection.Open();
                   MessageBox.Show("Mở kết nối thành công");

                   string mySQL = "SELECT [Story],[Beam], [CaseCombo], [Station], P, V2, V3, T, M2, M3 " + "From [Beam Forces]";
                   OleDbCommand cmd = new OleDbCommand(mySQL, MyConnection);
                   MessageBox.Show(mySQL);
                   OleDbDataReader dr = cmd.ExecuteReader();
                   DataTable dtb = new DataTable();
                   WorkSheet curSheet = Globals.ThisAddIn.Application.ActiveSheet;


                   ????????????????????????

                   MyConnection.Close();
               }
               catch (Exception ex)
               {
                   MessageBox.Show("Error: "+ ex);
               }

           }
