你需要做这样的事情：

            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();
