Answer 1

Use MimeBase.ContentType property:

MimeData mime = ... 
mime.ContentType = ContentType.Parse("Application/EDIFACT");

MimeBase.ContentTypeHeader.Name is used to specify "Name" on Content-Type header.

Answer 2

the result should contains something like this:
(i skipped the filename while this also results in the wrong Content-Type)

X-Original-Date: Tue, 27 Jun 2017 05:20:04 +0200
Content-Disposition: attachment;
filename="__4Y90BEQMY.edi"
Content-Type: Application/EDIFACT

---

Test with FileName results in:

Content-Type: multipart/mixed;
boundary="----=NextPart23458411.159013775632"
MIME-Version: 1.0
