C#中发送邮件代码 |
本文标签:C#,发送邮件 始找的代码只能发送无SMTP验证的邮件,但现在很多EMAIL发送时都需要验证,后来查找了下MSDN的帮助,找到了发送验证的代码,贴出来希望对大家有所帮助! 复制代码 代码如下: public static int sendmail(string to, string body,string subject) { try { int nContain = 0; ///添加发件人地址 string from = "你的发送EMAIL"; MailMessage mailMsg = new MailMessage(); mailMsg.From = new MailAddress(from); nContain += mailMsg.From.Address.Length; ///添加收件人地址 mailMsg.To.Add(to); nContain += mailMsg.To.ToString().Length; ///添加邮件主题 mailMsg.Subject = subject; mailMsg.SubjectEncoding = Encoding.UTF8; nContain += mailMsg.Subject.Length; ///添加邮件内容 mailMsg.Body = body; mailMsg.BodyEncoding = Encoding.UTF8; mailMsg.IsBodyHtml = true; nContain += mailMsg.Body.Length; if (mailMsg.IsBodyHtml == true) { nContain += 100; } ///发送邮件 try { //定义发送邮件的Client SmtpClient client = new SmtpClient(); //表示以当前登录用户的默认凭据进行身份验证 client.UseDefaultCredentials = true; //包含用户名和密码 client.Credentials = new System.Net.NetworkCredential(application.GetapplicationSendmail(), application.GetapplicationSendpass()); ///设置邮件服务器主机的IP地址 client.Host = "SMTP服务器IP" ///设置邮件服务器的端口 client.Port = 25; ///配置发送邮件的属性 client.DeliveryMethod = SmtpDeliveryMethod.Network; //System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(strFrom, strto, strSubject, strBody); mailMsg.Priority = System.Net.Mail.MailPriority.Normal; //client.UseDefaultCredentials = false; ///发送邮件 client.Send(mailMsg); return 1; } catch (Exception ex) { return 0; } } catch (Exception ex) { return 0; } } |
