Get attachments in an array of bytes using MimeKit in C#

How can I get the attachment content when using MimeKit? This is what I have:

var mimeMessage = MimeMessage.Load(@"test.eml");
var attachments = mimeMessage.Attachments.ToList();

foreach (var attachment in attachments)
{
    // how do I get the content here (array of bytes or stream)
}
