如何向Stimulsoft发送参数？

    public virtual ActionResult GetReportSnapshot()
    {
       var data = (ComparativeBalanceReportDS) TempData["ComparativeSession"];


        StiReport report = new StiReport();
        report.Load(Server.MapPath("~/Content/StimulReports/SampleReport.mrt"));

        report.Compile();

        report["fromDocumentNumber"] = "1";
        report["toDocumentNumber"] = "85";
        return StiMvcViewer.GetReportSnapshotResult(HttpContext, report);
   }
