C#邮件发送代码

<textarea cols="89" rows="20" name="code" class="c-sharp">过.Net FrameWork 2.0下提供的&ldquo;System.Net.Mail&rdquo;可以轻松的实现,本文列举了3种途径来发送: 1.通过Localhost; 2.通过普通SMTP; 3.通过SSL的SMTP; 下面一个一个来说: 1.通过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]");可以发送给多人 */ msg.CC.Add("[email protected]"); /**//* * msg.CC.Add("[email protected]"); * msg.CC.Add("[email protected]");可以抄送给多人 */ msg.From = new MailAddress("[email protected]", "AlphaWu", System.Text.Encoding.UTF8); /**//* 上面3个参数分别是发件人地址(可以随便写),发件人姓名,编码*/ msg.Subject = "这是测试邮件";//邮件标题 msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码 msg.Body = "邮件内容";//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 = "localhost"; object userState = msg; try ...{ client.SendAsync(msg, userState); //简单一点儿可以client.Send(msg); MessageBox.Show("发送成功"); } catch (System.Net.Mail.SmtpException ex) ...{ MessageBox.Show(ex.Message, "发送邮件出错"); } } 2.通过普通SMTP public void SendMailUseZj() ...{ 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]");可以发送给多人 */ msg.CC.Add("[email protected]"); /**//* * msg.CC.Add("[email protected]"); * msg.CC.Add("[email protected]");可以抄送给多人 */ msg.From = new MailAddress("[email protected]", "AlphaWu", System.Text.Encoding.UTF8); /**//* 上面3个参数分别是发件人地址(可以随便写),发件人姓名,编码*/ msg.Subject = "这是测试邮件";//邮件标题 msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码 msg.Body = "邮件内容";//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.Credentials = new System.Net.NetworkCredential("[email protected]", "userpass"); //在zj.com注册的邮箱和密码 client.Host = "smtp.zj.com"; object userState = msg; try ...{ client.SendAsync(msg, userState); //简单一点儿可以client.Send(msg); MessageBox.Show("发送成功"); } catch (System.Net.Mail.SmtpException ex) ...{ MessageBox.Show(ex.Message, "发送邮件出错"); } } 上述方法不适用于所有SMTP,经测试zj.com可以,而smtp.163.com不行 3.通过SSL的SMTP public void SendMailUseGmail() ...{ 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]");可以发送给多人 */ msg.CC.Add("[email protected]"); /**//* * msg.CC.Add("[email protected]"); * msg.CC.Add("[email protected]");可以抄送给多人 */ msg.From = new MailAddress("[email protected]", "AlphaWu", System.Text.Encoding.UTF8); /**//* 上面3个参数分别是发件人地址(可以随便写),发件人姓名,编码*/ msg.Subject = "这是测试邮件";//邮件标题 msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码 msg.Body = "邮件内容";//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.Credentials = new System.Net.NetworkCredential("[email protected]", "password"); //上述写你的GMail邮箱和密码 client.Port = 587;//Gmail使用的端口 client.Host = "smtp.gmail.com"; client.EnableSsl = true;//经过ssl加密 object userState = msg; try ...{ client.SendAsync(msg, userState); //简单一点儿可以client.Send(msg); MessageBox.Show("发送成功"); } catch (System.Net.Mail.SmtpException ex) ...{ MessageBox.Show(ex.Message, "发送邮件出错"); } } </textarea>
