Problem when saving docx to stream

[mzahumensky]

Hi,
I have Word 2010 file on HDD.

I need download file as attachment from ASPX application and I cannot save doc to the file (hosting & permissions). Stream I am sending by this code:
Response.ContentType = "application/msword"
Response.AddHeader("Content-Disposition", "attachment;filename=Licence.docx")
Response.BinaryWrite(s.GetBuffer())

After I opened it (doc.LoadFromFile(filename, FileFormat.Docx)) I can save it to disc (doc.SaveToFile (filename2, FileFormat.Docx)) and everything is ok.
When I didn't save document to disc, but to the stream (doc.SaveToStream(stream, FileFormat.Docx)), document is corrupted

Do you have some ideas what can be wrong?

Martin

Dear Martin,
Thanks for your inquiry.
Your code have some problem. You can do it like this.

Code: Select all

 using (MemoryStream stream = new MemoryStream())
            {
                doc.SaveToStream(stream, FileFormat.Docx);
                Response.Clear();
                Response.ContentType = "application/msword";
                Response.AppendHeader("Content-Disposition:", "attachment; filename=Licence.docx");
                Response.AppendHeader("Content-Length", stream.Length.ToString());
                Response.ContentType = "application/download";
                Response.BinaryWrite(stream.ToArray());
                Response.Flush();
            }

Dear Justin
Thank you very much for fast and perfect answer

My missing code is this
Response.AppendHeader("Content-Length", stream.Length.ToString());

Have a nice day!
