Why are .docx files being corrupted when downloading from an ASP.NET page?

Question

I have this following code for bringing page attachments to the user:

private void GetFile(string package, string filename)
{
    var stream = new MemoryStre         


        

Answer 1

I also ran into this problem and actually found the answer here: http://www.aspmessageboard.com/showthread.php?t=230778

It turns out that the docx format needs to have Response.End() right after the Response.BinaryWrite.
