PDF file error Cannot access a closed Stream

Question

I would like to generate a PDF file for my reporting module. Here is my code in the controller in generating the PDF file.

public ActionResult Reports_CARF(int carf_id= 0) 
{
    var data = db.Dept_Approval_Data_vw.Where(x => x.carf_id == carf_id && x.request_category == "PETC Local Applications" && x.verified_by != null).ToList();

    return new PdfActionResult(data);
}

I have include this following in my controller:

using MvcRazorToPdf;
using iTextSharp.text;
using iTextSharp.text.pdf;

Now, when I try to run this code, I got this error displayed in the browser.

Please advice. Thanks in advance.

Answer 1

Based on personal experience, this is likely to be badly formed XHTML coming from your view causing an unhandled exception in MvcRazorToPdf.

Try rendering the view, e.g. return View() instead of return new PdfActionResult(data), and running the output through an XHTML validator.
