     string sql = "SELECT * FROM Worker "; 
     SqlConnection connection = new SqlConnection(connectonString); 
     SqlDataAdapter da = new SqlDataAdapter(sql, connection); 
     DataTable dt = new DataTable(); 

     da.Fill(dt); 
     CrystalReport1 cr = new CrystalReport1();

你需要做這樣的事情：

  Invoice invoice = new Invoice(); // instance of my rpt file 
      var ds = new DsBilling(); // DsBilling is mine XSD 
      var table2 = ds.Vendor; 
      var adapter2 = new VendorTableAdapter(); 
      adapter2.Fill(table2); 


      var table = ds.Bill; 
      var adapter = new BillTableAdapter(); 
      string name = cboCustReport.Text; 
      int month = int.Parse(cboRptFromMonth.SelectedItem.ToString()); 
      int year = int.Parse(cboReportFromYear.SelectedItem.ToString()); 
      adapter.Fill(table, name,month,year); 

      ds.AcceptChanges(); 

      invoice.SetDataSource(ds); 
      crystalReportViewer1.ReportSource = invoice; 
      crystalReportViewer1.RefreshReport();
