C#發送Email方法總結

 

通過.Net FrameWork 2.0下提供的“System.Net.Mail”可以輕松的實現，本文列舉了3種途徑來發送： 
1.通過Localhost； 
2.通過普通SMTP; 
3.通過SSL的SMTP;

下面一個一個來說：

1.通過LocalHost

public void SendMailLocalhost()         {             System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();             msg.To.Add("[email protected] ");             msg.To.Add("[email protected] ");             /*              * msg.To.Add("[email protected]");              * msg.To.Add("[email protected]");              * msg.To.Add("[email protected]");可以發送給多人              */             msg.CC.Add("[email protected] ");             /*              * msg.CC.Add("[email protected]");              * msg.CC.Add("[email protected]");可以抄送給多人              */                        msg.From = new MailAddress("[email protected] ", "AlphaWu ", System.Text.Encoding.UTF8);             /* 上面3個參數分別是發件人地址（可以隨便寫），發件人姓名，編碼*/             msg.Subject = "這是測試郵件 ";//郵件標題                        msg.SubjectEncoding = System.Text.Encoding.UTF8;//郵件標題編碼             msg.Body = "郵件內容 ";//郵件內容             msg.BodyEncoding = System.Text.Encoding.UTF8;//郵件內容編碼             msg.IsBodyHtml = false ;//是否是HTML郵件             msg.Priority = MailPriority.High;//郵件優先級               SmtpClient client = new SmtpClient();             client.Host = "localhost ";             object userState = msg;             try             {                                client.SendAsync(msg, userState);                 //簡單一點兒可以client.Send(msg);                 MessageBox.Show("發送成功 ");             }             catch (System.Net.Mail.SmtpException ex)             {                 MessageBox.Show(ex.Message, "發送郵件出錯 ");             }             }

2.通過普通SMTP
