用.net简单写个E-mail发送功能及扩展功能

//引下以下空間：using System.Net.Mail;//簡單實例：   //去163.com申請個帳號試試，如果有最好，呵呵//注意using 和加入Page_Load內代碼運行一下即可發送//public partial class SendEmail : System.Web.UI.Page//{    protected void Page_Load(object sender, EventArgs e)    {        //发送        string strSmtp = "stmp.163.com";        string strSendEmail = "發送者郵件地址";        string strUserName = "申請人用戶名";        string strPassWord = "申請人密碼";        string strRecieveEMail = "接收者郵件地址";        string strSubject = "主題";        string strBody = "內容";        System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();        msg.To.Add(strRecieveEMail);        附件處理        //if (txtAttachment.Text.Trim().Length > 0)        //{        //    string FileName = @txtAttachment.Text.Trim();        //    System.Net.Mail.Attachment pAttachment = new Attachment(FileName);        //    msg.Attachments.Add(pAttachment);        //}        msg.From = new MailAddress(strSendEmail) ;                msg.Subject = strSubject;//邮件标题                     msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码         msg.Body = strBody;//邮件内容         msg.BodyEncoding = System.Text.Encoding.UTF8;//邮件内容编码         msg.IsBodyHtml = false;//是否是HTML邮件         msg.Priority = MailPriority.High;//邮件优先级

        SmtpClient client = new SmtpClient();        client.Host = strSmtp;//为邮件服务器设置        System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential(strUserName, strPassWord);        client.Credentials = basicAuthenticationInfo;

        object userState = msg;        try        {            client.Send(msg);            //client.SendAsync(msg, userState);//简单一点儿可以client.Send(msg);             Response.Write("成功发送到" + strRecieveEMail + "邮箱");        }        catch (System.Net.Mail.SmtpException ex)        {            Response.Write("发送邮件出错");            throw ex;        }    }//}擴展：1.郵件群發，弄一下輸入框，以“，”格開各郵件地址，使用split函數，寫一個循環便可實現。2.郵件重發，郵件地址不變，寫一個循環，狂發，哈哈，別干惡作劇哦。

有需要此類完整代碼的，請留下E_mail。
