Attachment.FileName returnes diffferent than what I see in mail client

Question

I have a mail with 3 attachments with same name - let's say image.jpg. But FileName and DisplayName for those attachments return image.jpg, image(1).jpg, image(2).jpg.
I also have other e-mail with winmail.dat attached where there are two files with same name inside - [Untitled].pdf and for both of those FileName returns [Untitled].pdf.

I don't know what is the convention and how should I get attachment's name.

Answer 1

DisplayName property is supposed to reflect the original file name value (as present in the email data), while FileName should be "safe" version of it (meaning it's a valid file name and not a duplicate).

So based on your description, it looks like the first mail really did contain image.jpg, image(1).jpg and image(2).jpg files, while the other mail might not be processed by Rebex Mail properly.

We'll look into this. An issue like this could easily got overlooked because TNEF/winmail.dat mail messages have been quite rare for years. If you could share a sample of these emails, it would be helpful. Thanks for letting us know about this!

Comments

I have sent an example e-mail for case where (1), (2) is returned for FileName and DisplayName.

Thanks, we have now succeeded in reproducing thtis. The DisplayName property is not behaving as intended - it should contain the original file name (same in those three cases). We'll fix this as well. Thanks for letting us know!

Update: This has been fixed in 2019 R3.2 release: https://www.rebex.net/total-pack/history.aspx#2019R3.2
