How do i add multiple attachments to my email webservice so that users can consume to send multiple attachments using C#

Im using the System.Net.mail namespace and am creating a webservice to send emails.

i would like to add a webmethod where a collection of attachments could be added to the email. There are many examples with single attachement.

Please suggest with code. Below is my class for sending the email which i call in the webservice.

MailAddress from = new MailAddress(From);
            MailAddress to = new MailAddress(To);
            MailMessage mail = new MailMessage(from , to);
            if (Cc.Length > 0)
            {
                MailAddress copy = new MailAddress(Cc);
                mail.CC.Add(copy);
            }
            if (Bcc.Length > 0)
            {
                MailAddress bcopy = new MailAddress(Bcc);
 
                mail.Bcc.Add(bcopy);
            }
            if (Subject.Length > 0)
            {
                mail.Subject = Subject;
            }
            if (Body.Length > 0)
            {
                mail.Body = Body;
            }
            mail.IsBodyHtml = true;
            
 
                
                //Send the message.
                SmtpClient client = new SmtpClient(GetSmtpServer());
                client.Send(mail);
}
