报表传参数问题

Question

 this.reportViewer1.LocalReport.ReportEmbeddedResource = "Report1.rdlc";
            ReportParameter rp = new ReportParameter("name", "tt");
          //  this.reportViewer1.LocalReport.SetParameters(rp);
            this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { rp });
            this.reportViewer1.RefreshReport();
为什么说name缺少参数值啊，name是报表中的一个参数名，
您如果曾经做过报表，能不能发给我一个关于传参数的实例啊

Answer 1

 this.Cursor = Cursors.WaitCursor;
                            CsReport.CS02690CLS report = new LMS.CsReport.CS02690CLS();
                            report.Viewer = true;
                            report.ZoomLevel = 100;
                            report.FormWindowState = FormWindowState.Maximized;
                            report.SetDataSource(ds.Tables[0]);
                            report.Publish();
