How can I copy Response.Outputstream to MemoryStream? The error is:

Thank you in advance
Why not writing to your memory stream then copy it to the response output stream ?
string pdfTemplate = Server.MapPath(@"~\Pdf\132331.pdf");
Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + fileName + ".pdf");
Response.Clear();
using (var memoryStream = new MemoryStream())
{
using (PdfStamper pdfStamper = new PdfStamper(new PdfReader(pdfTemplate), memoryStream))
{
pdfStamper.FormFlattening = true;
PdfContentByte pdfPage = pdfStamper.GetOverContent(1);
AcroFields pdfFormFields = pdfStamper.AcroFields;
// pdf stuff here
}
// Memory stream is closed by PdfStamper, so we should read the inner buffer with ToArray()
byte[] buffer = memoryStream.ToArray();
Response.OutputStream.Write(buffer, 0, buffer.Length);
}
Response.Flush();
PdfStamper need to be closed before to get the content in the memory stream. Dispose implicitly call the Close method, so when you get out of the using statement of the PdfStamper, it will be closed automatically.
PdfStamper also close the memory stream when disposed, so you should read the buffer on the memory stream with ToArray.
