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

bool success;
success = mime.UnlockComponent("Anything for 30-day trial.");
if (success == false) {
    textBox1.Text += mime.LastErrorText + "\r\n";
    return;
}

//  Set the MIME body:
mime.SetBody("This is a test");

//  The complete size (in bytes) of the contents is computed,
//  even if the MIME is multipart, and the Content-Length header
//  is added.
mime.AddContentLength();

//  Display the MIME:
textBox1.Text += mime.GetMime() + "\r\n";
