Problem to parse mail with 2 multiparts - one inside of other

Hi guys,

i face an issue with “strange” TWO multipart EML structure (please see attachment).
Email object can’t parse it correctly -> e.g. doesn’t see any LinkedResources.

Additionally when i save Email as MHTML and try to open as AsposeWords Document:

lEml.Save(lStreamMHT);
lStreamMHT.Position = 0;

Aspose.Words.LoadOptions lLoadOptions = new Aspose.Words.LoadOptions();
lLoadOptions.LoadFormat = Aspose.Words.LoadFormat.Mhtml;

Aspose.Words.Document lDocument = new Aspose.Words.Document(lStreamMHT, lLoadOptions);

I get following exception: Unsupported target content type in a multipart/related structure: text/plain.

Any idea?

Hi Ondrej,


Thank you for writing to Aspose Support team.

You can find the information about the linked resources in the alternate view of the EML file using the following code:

Sample Code:

MailMessage eml = MailMessage.Load(“761341\two_multipart.eml”);

Console.WriteLine(eml.AlternateViews[0].LinkedResources.Count);

For your other issue, we were able to observe the problem. Our fellow team member for Aspose.Words team will soon assist you in this regard.

Hi Kashif,
please, could you shortly explain the idea of AlternateViews?
I'm not sure how do i know where "attachments / linked resources" can be found?

Thank you!
Ondrej

Hi Ondrej,


If the LinkedResources collection of MailMessage is empty, you can check for these in Alternate views of the MailMessage API.

Hi Tahir,

Any idea?

Best regards,
