How to convert pdf Byte[] Array to downloadable file using iTextSharp

Question

Hei guys I have this byte array i want to convert to pdf and make it available for download. Anybody has any idea how this is done?

here is my Action Controller

Answer 1

I am using similar code with a few differences:

Response.Clear();
MemoryStream ms = new MemoryStream(pdfByte);
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=labtest.pdf");
Response.Buffer = true;
ms.WriteTo(Response.OutputStream);
Response.End();

1. Call Reponse.Clear() earlier.
2. Use MemoryStream.WriteTo to write to Response.OutputStream.

Edit: sorry, I didn't see that you are using ASP.NET MVC, the above code is in a WebForms aspx page.

For ASP.NET MVC, couldn't you just do

return new FileStreamResult(ms, "application/pdf");

?
