opening a word file in browser using C#

Question

I am trying to open/download a word file on a browser using C#. The process is working for PDF files, but not for .doc files. It donwloads as a "application/octet-stream (100 kB)"

My code is:

        FileStream fs = new FileStream(Server.MapPath(@"~\Content\documetfile.doc"), FileMode.OpenOrCreate, FileAccess.ReadWrite);
        return File(fs, "documentfile.doc");

What do i need to do to make it download as a word file ?

Answer 1

You need to specify correct content type: "application/vnd.ms-word":

  return File(fs, "application/vnd.ms-word", "documentfile.doc");
