MailKit save Attachments

Question

I'm try save attachments from message

foreach(MimeKit.MimeEntity at message.Attachments) 
{
    at.WriteTo("nameFile");
}

File saved, but when I open I get the error the file is corrupted or too large The size of this file is 88 kb, but size of the file should be equal to 55 kb.

I think that in all recorded message file.

How do I only record the attachment?

You are saving the entire MIME object (including the headers). What you need to do is save the content.

foreach (var attachment in message.Attachments) {
    using (var stream = File.Create ("fileName")) {
        if (attachment is MessagePart) {
            var part = (MessagePart) attachment;

            part.Message.WriteTo (stream);
        } else {
            var part = (MimePart) attachment;

            part.Content.DecodeTo (stream);
        }
    }
}
