bool success = false;

Chilkat.Email email = new Chilkat.Email();

//  First populate a simple email.
email.Subject = "This is the subject.";
email.Body = "This is a simple email body.";
email.From = "Chilkat Software <support@chilkatsoft.com>";
email.AddTo("Some Recipient","someRecipient@somewhere.com");

//  Load a JPG file.
//  The actual source of your attachment data can come from anywhere.
//  The point here is that we're first getting the bytes in memory, and THEN adding
//  the bytes as an attachment.
Chilkat.FileAccess fac = new Chilkat.FileAccess();
byte[] jpgBytes = null;
jpgBytes = fac.ReadEntireFile("qa_data/jpg/starfish20.jpg");

//  Add the JPG bytes via AddDataAttachment.
email.AddDataAttachment("tinyStarfish.jpg",jpgBytes);

//  We could also add the JPG and explicitly set the content-type w/ AddDataAttachment2
email.AddDataAttachment2("teenyStarfish.jpg",jpgBytes,"image/jpg");

//  Examine the MIME:
Debug.WriteLine(email.GetMime());

//  This is the MIME of the email:
