.NET 2.0否决了原来的System.Web.Mail，而启用新的命名空间System.Net.Mail。注意要实现SMTP时，别忘了using System.Net;和using System.Net.Mail;

下面看SMTP的核心代码

public bool SendEmail(string strServerAddress,string strServerPort,string strServerUID,string strServerPWD,string strSenderEmail,string strReceiverEmail,string strSubject,string strBody,string strAttachment)
        {
            try
            {
                SmtpClient smtp = new SmtpClient(strServerAddress, int.Parse(strServerPort));
                smtp.Credentials = new NetworkCredential(strServerUID, strServerPWD);
                MailMessage mail = new MailMessage(strSenderEmail, strReceiverEmail, strSubject, strBody);
                if (strAttachment != string.Empty)
                {
                    Attachment file = new Attachment(strAttachment);
                    mail.Attachments.Add(file);
                }
                smtp.Send(mail);
                return true;
            }
            catch
            {
                return false;
            }
        }
