rdlc报告中提供的链接中的Querystring问题

Question

我有一个在asp.net Web应用程序中使用RDLC创建的报告。当我单击报告中的链接时，该链接的查询字符串附加了两次

如下所示，由于未显示哪个文件。

../ OpenPdfFileSupplier.aspx？FileName = filename.pdf＆FileName = filename.pdf

在我的开发机器上没有找到导致此问题的根本原因。 请协助解决此问题。

 urlUAT = "http://" + HttpContext.Current.Request.Url.Authority  + HttpContext.Current.Request.ApplicationPath 
                    + "/OpenPdfFileSupplier.aspx?FileName=";
                ReportParameter[] rptParam;
                rptParam = new ReportParameter[5];
                rptParam[0] = new ReportParameter("FromDate", Request.QueryString["d1"]);
                rptParam[1] = new ReportParameter("ToDate", Request.QueryString["d2"]);
                rptParam[2] = new ReportParameter("Url", urlUAT);
                string url1 = "http://" + HttpContext.Current.Request.Url.Authority + prtValue + 
                    HttpContext.Current.Request.ApplicationPath + "/VendorPaymentReceipt.aspx?sid=#id&pid=#pid&filename=#filename";
                string url2 = "http://" + HttpContext.Current.Request.Url.Authority + prtValue + 
                    HttpContext.Current.Request.ApplicationPath + "/SupplierPaymentDocuments.aspx?sid=#id";


                rptParam[3] = new ReportParameter("url1", url1);
                rptParam[4] = new ReportParameter("url2", url2);

              //  rptViewer1.Width = 1000;
                rptViewer1.ProcessingMode = ProcessingMode.Local;
                rptViewer1.LocalReport.ReportPath = strReportPath;

                rptViewer1.LocalReport.EnableHyperlinks = true;

                rptViewer1.LocalReport.DataSources.Clear();
                ReportDataSource rdf = new ReportDataSource(strDatasource, dt);
                this.rptViewer1.LocalReport.DataSources.Clear();
                rptViewer1.LocalReport.DataSources.Add(rdf);
                rptViewer1.LocalReport.SetParameters(rptParam);
                rptViewer1.LocalReport.Refresh();
