Recognize file MIME type

Question

Could I determine the mime type of files using your Mail.dll? However these files aren't email attachments.

Answer 1

When the file is added to an email as a attachment (using MailBuilder class), ContentType is set according to the file's extension:

 MailBuilder builder = new MailBuilder();
 MimeData attachment = builder.AddAttachment("c:\\report.xml");

 Assert.AreEqual(ContentType.TextXml, attachment.ContentType);
