如何通过Response.BinaryWrite（）留下空白页？

Question

我正在使用.NET Reponse.BinaryWrite（）方法在代码中获取Byte []值并将其生成为pdf文件。我需要在某个页面上留一个空页面。是否可以这样做？

 protected override void Render(HtmlTextWriter writer)
    {
        base.Render(writer);
        string mimeType;
        string encoding;
        string fileNameExtension;
        string[] streams;
        Microsoft.Reporting.WebForms.Warning[] warnings;

        Byte[] reportDoc;
        Response.Clear();
        switch (Request.QueryString["report"].ToString().ToLower())
        {
            case "rpt_penetrantlog":
            case "rpt_proccdbyregion":
            case "rpt_ordersbycustomeranddate":
            case "rpt_hold":
                reportDoc = rptviewOzark.LocalReport.Render("Excel", null, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
                Response.ContentType = mimeType;
                Response.AddHeader("content-disposition", "attachment; filename=Report.xls");
                break;
            default:
                reportDoc = rptviewOzark.LocalReport.Render("PDF", null, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
                Response.ContentType = "application/pdf";
                break;
        }

        Response.BinaryWrite(reportDoc);
        Response.Flush();
        Response.End();
    }
