Mime m = new Mime();  
MimeEntity mainEntity = m.MainEntity;  
// Force to create From: header field  
mainEntity.From = new AddressList();  
mainEntity.From.Add(new MailboxAddress(txtFrom.Text, txtFrom.Text));  
 // Force to create To: header field  
 mainEntity.To = new AddressList();  
 mainEntity.To.Add(new MailboxAddress(txtTo.Text, txtTo.Text));  
mainEntity.Subject = txtSubject.Text;  
//添加正文
