// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Mime mime = new Chilkat.Mime();

bool success = mime.SetBodyFromFile("VoiceMessage.wav");
if (success == false) {
    Debug.WriteLine(mime.LastErrorText);
    return;
}

// The MIME has this header:
// Content-Disposition: attachment;
// 	 filename="VoiceMessage.wav"
// Content-Transfer-Encoding: base64
// Content-Type: audio/x-wav;
// 	name="VoiceMessage.wav"

// We don't want the content-disposition to be an
// attachment -- otherwise the email object will self-correct
// and put it in a multipart/mixed format...
mime.Disposition = "";
mime.Filename = "";

string strMime;
strMime = mime.GetMime();
Debug.WriteLine(strMime);

// Now load it into an email object:
Chilkat.Email email = new Chilkat.Email();
success = email.SetFromMimeText(strMime);
if (success == false) {
    Debug.WriteLine(email.LastErrorText);
    return;
}

// Add subject, TO, FROM, etc.
email.Subject = "This is a test";
email.From = "support@chilkatsoft.com";
success = email.AddTo("Matt","matt@chilkatsoft.com");

// Your email is ready to send.
// (but for this example, we'll simply save it to a file...)
success = email.SaveEml("email.eml");
if (success == false) {
    Debug.WriteLine(email.LastErrorText);
    return;
}

Debug.WriteLine("OK!");
