How to send email messages with attachments

Sending E-mail messages from Microsoft Dynamics AX could be a bit tricky.
The most recommended way to do so is by using the standard mail mechanism built in the system.The Email sending status form (based on tableSysOutgoingEmailTable) and the E-mail distributor batch job.
But if you want to send email with attachments and more advance options, you should do so with .NET Framework, and the System.Net.Mail object.
First of all, make sure you have a correctly configured SMTP server.
Go to Administration -> Setup -> E-mail parameters and fill the required settings:
(Form: SysEmailParameters)
Then, use this code sample:
void SendMail()

    System.Net.Mail.MailMessage             mailMessage;
    System.Net.Mail.Attachment              attachment;
    System.Net.Mail.AttachmentCollection    attachementCollection;
    System.Net.Mail.SmtpClient              smtpClient;
    System.Net.Mail.MailAddress             mailAddressFrom;
    System.Net.Mail.MailAddress             mailAddressTo;
    str                                     Body;
    str                                     Subject;
    str                                     SMTPServer;
    str                                     FileName;
    FileIOPermission                        perm;

    mailAddressFrom = new System.Net.Mail.MailAddress("","");
    mailAddressTo = new System.Net.Mail.MailAddress("","");
    Body = "<B>Body of the email</B>";
    Subject = "Subject line for the email";
    SMTPServer = SysEmailParameters::find(false).SMTPRelayServerName;

    mailMessage = new System.Net.Mail.MailMessage(mailAddressFrom, mailAddressTo);
    attachementCollection = mailMessage.get_Attachments();

// Add attachemnts! use double slashes ("\") in the filename path.
    FileName = "C:\\test.bmp";
    perm = new FileIOPermission(FileName,'w');

    attachment = new System.Net.Mail.Attachment(FileName);
    smtpClient = new System.Net.Mail.SmtpClient(SMTPServer);
