Sending Email by System.Net.Mail in AX

　　We could easyly to write a method to send the mail by C#, in axapta we can use the System.Net.Mail to send mail as C#.

void sendMail
(
    str _Subject,
    str _MailTo,
    str _CCTo,
    str _Body,
    str _Attachment
)
{
    System.Net.Mail.MailAddress                 mailFrom;
    System.Net.Mail.MailMessage                 mailer;
    System.Net.Mail.MailAddressCollection       mailerConn;
    System.Net.Mail.AttachmentCollection        mailerAttachment;
    System.Net.Mail.SmtpClient                  smtpClient;

    System.Exception                            ex;

    List              m_MailTo, m_CCTo, m_Attachment;
    ListEnumerator    m_LE;
    str               m_MailAddress, m_MailerAttachment;
　  InteropPermission interopPermission;
　  ;

　  interopPermission = new InteropPermission(InteropKind::ClrInterop);
　  interopPermission.assert();
    mailFrom = new System.Net.Mail.MailAddress("*********", "**********");//Sender address; display name
    mailer   = new System.Net.Mail.MailMessage();

    mailer.set_From(mailFrom);
    mailer.set_Subject(_Subject);
    mailer.set_Body(_Body);

    //Set mail to
    mailerConn = mailer.get_To();
    m_MailTo   = Global::strSplit(_MailTo, ";");
    m_LE       = m_MailTo.getEnumerator();
    while (m_LE.moveNext())
    {
        m_MailAddress = m_LE.current();
        mailerConn.Add(m_MailAddress);
    }

    //Set CC to
    mailerConn = mailer.get_CC();

        mailerAttachment.Add(new System.Net.Mail.Attachment(m_MailerAttachment));
    }

    //Set sender parameters
    mailer.set_BodyEncoding(System.Text.Encoding::get_UTF8());
    mailer.set_IsBodyHtml(true);
    mailer.set_Priority(System.Net.Mail.MailPriority::Normal);
    mailer.set_DeliveryNotificationOptions(System.Net.Mail.DeliveryNotificationOptions::OnSuccess);

    try

        smtpClient.set_DeliveryMethod(System.Net.Mail.SmtpDeliveryMethod::Network);

        //Send mail
        smtpClient.Send(mailer);
    }
    catch (Exception::CLRError)
