我在水晶报表中的代码

    private void crystalReportViewer1_Load(object sender, EventArgs e)
    {
        this.crystalReportViewer1.RefreshReport();
        rd = new ReportDocument();
        String reportpath = Application.StartupPath;
        reportpath = reportpath.Substring(0, reportpath.LastIndexOf("bin"));
        rd.Load(reportpath + "PatientReportNonReactive.rpt");
        DataSet ds = prc.nonReactiveReportNew(cond);
        rd.SetDataSource(ds.Tables[0]);
        crystalReportViewer1.ReportSource = rd;
        crystalReportViewer1.RefreshReport();
    }
