c# - 在使用ironpdf将url转换为pdf期间打开pdf而不保存它

Question

我正在使用ironpdf 将 url 转换为 pdf。转换成功，但我必须将文档保存在某个位置。是否可以只显示为内存流或字节数组？

            string authority = HttpContext.Current.Request.Url.Authority;
            string val = "http://"+authority + "/Report/PrintReport.aspx?ID=" + vciInfoReportid;
            string fileName = "url.pdf";
            string fileloc = HttpContext.Current.Server.MapPath("~/"+fileName);
            Renderer.RenderUrlAsPdf(val).SaveAs(fileloc);

Answer 1

我找到了解决方案。有一个内置方法

            //Conversion of the ASPX file into PDF

            MemoryStream rend=Renderer.RenderUrlAsPdf(val).Stream;

            HttpContext.Current.Response.AddHeader("Content-Type", "application/pdf");

            // let the browser know how to open the PDF document, attachment or inline, and the file name
            HttpContext.Current.Response.AddHeader("Content-Disposition", String.Format("{0}; filename=Print.pdf; size={1}",
              "attachment", rend.Length.ToString()));

            // write the PDF buffer to HTTP response
            HttpContext.Current.Response.BinaryWrite(rend.ToArray());

            // call End() method of HTTP response to stop ASP.NET page processing
            HttpContext.Current.Response.End();
