File CopyTo Problem & Multiple Outputs

ugursusta

Hello,
I want to copy my view in mvc to an output.pdf of my choosing. I could do that using the code fragment below but it both writes to output file and tries to open the view in browser.

[EnableJsReport()]
        public ActionResult Report()
        {
            string outPath = @"SomePath\Out.pdf";
            HttpContext.JsReportFeature()
                .Recipe(Recipe.ChromePdf)
                .OnAfterRender((r) =>
                {
                    using (FileStream outFile = System.IO.File.Create(outPath))
                    {
                        r.Content.CopyTo(outFile);
                    }
                });

            return View(new ReportModel());
        }

But in browser I get Failed to Load PDF Document error each and every time. So I get the out file but view gets broken.
What I really want is save a copy of report to my server and download a copy from client. And for that I used the code below(old code with download line added):

[EnableJsReport()]
        public ActionResult Report()
        {
            string outPath = @"SomePath\Out.pdf";
            HttpContext.JsReportFeature()
                .Recipe(Recipe.ChromePdf)
                .OnAfterRender((r) =>
                {
                    HttpContext.Response.Headers["Content-Disposition"] = "attachment; filename=\"myReport.pdf\"";
                    using (FileStream outFile = System.IO.File.Create(outPath))
                    {
                        r.Content.CopyTo(outFile);
                    }
                });

            return View(new ReportModel());
        }

I get the behavior I want but the problem above breaks downloaded pdf and when I open I get same Failed to Load PDF File error. How can I fix this?
Thanks in advance.

I think that when using r.Content.CopyTo you get to the end of the stream.
You need to seek back to beginning afterward if you want to read it again.
Something like

r.Content.Position = 0;

Yea guess you are right. It is working properly now. Thank you so much!
