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

You should not use stream.GetBuffer() because it returns the buffer array which might contain unused bytes. Use stream.ToArray() instead. Also, have you tried calling stream.Seek(0, SeekOrigin.Begin) before writing anything?
