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

As variant for .NET Framework 3.5 and lower. This version of framework haven't method CopyTo in class Stream. Therefore, method WriteTo is replaced by next code:

byte[] arr = documentStream.ToArray();
fileStream.Write(arr, 0, arr.Length);
