Response.Clear(); MemoryStream ms = new MemoryStream(pdfContent); //Pass the rendered byte array from back end. Response.ContentType = "application/pdf"; Response.AddHeader("content-disposition", "attachment;filename=Sample.pdf"); Response.Buffer = true; ms.WriteTo(Response.OutputStream); Response.End(); |

Thank you, can you tell me what is the problem with this file, I can not open it ?(attachment)
|
Here the attached document is not in proper PDF structure. It just contains the byte values. Hence it causes the document to be corrupted. |
|
//ms.Close(); By the way is closing and disposing useful here ? |
Yes, it will help to reduce the memory consumed by the application. |
Hi,
The document which you have sent is not a valid PDF document, you can check this by opening the PDF document in the Adobe Reader. We suspect that the code "result.Content.ReadAsByteArrayAsync().Result" does not returns proper PDF bytes as it contains only junk content. Could you please check the implementation of this in your code base.
