Streaming In Memory Word Document using OpenXML SDK w/ASP.NET results in “corrupt” document

Question

I am unable to stream a word document that I create on the fly down to the browser. I am constantly getting a message from Microsoft Word that the document is corrupt.

Answer 1

I believe your ContentType value is incorrect; that is for Word 97 - 2003 format. Change it to:

application/vnd.openxmlformats-officedocument.wordprocessingml.document

and see if that fixes the problem.
