163和腾讯企业邮箱 发邮件，多个附件
1、腾讯企业邮箱发送 报错：mail from address must be same as authorization user
用账号密码登录，不要用微信扫。进入后：点 设置——邮箱绑定——生成新密码。用新密码代替原登录密码。因为这里显示“关闭安全登录”，说明已经开启了安全登录。
2、465 端口发送邮件
/// <summary> /// 465 端口发送邮件 带附件 /// </summary> /// <param name="mailHost">邮件服务器</param> /// <param name="mailPort">端口</param> /// <param name="strSendMail">发送邮件的用户名</param> /// <param name="mailPassword">发送邮件的密码</param> /// <param name="strToList">收件人邮箱地址</param> /// <param name="file">附件地址</param> /// <param name="subject">邮件主题</param> /// <param name="body">内容</param> public static void Sendmail(string mailHost, string strSendMail, string mailPassword, string strToList, string subject = "", string body = "", List<string> file = null) { try { System.Web.Mail.MailMessage mmsg = new System.Web.Mail.MailMessage(); //验证 mmsg.Subject = subject;// "zhuti1";//邮件主题 mmsg.BodyFormat = System.Web.Mail.MailFormat.Html; mmsg.Body = body;// "wqerwerwerwer";//邮件正文 mmsg.BodyEncoding = Encoding.UTF8;//正文编码 mmsg.Priority = System.Web.Mail.MailPriority.High;//优先级 //添加邮件附件，可发送多个文件 if (file != null && file.Count() > 0) { foreach (var filename in file) { System.Web.Mail.MailAttachment mailAttach_1 = new System.Web.Mail.MailAttachment(filename); mmsg.Attachments.Add(mailAttach_1); } } //发件者邮箱地址 mmsg.From = strSendMail; mmsg.To = strToList;//收件人收箱地址 mmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");//身份验证 //登陆名 邮箱登录账号，这里跟前面的发送账号一样就行 mmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", mmsg.From); //登陆密码 这个密码要注意：如果是一般账号，要用授权码；企业账号用登录密码 mmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", mailPassword); mmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", 465);//端口 //SSL加密 mmsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true"); ////企业账号用smtp.exmail.qq.com System.Web.Mail.SmtpMail.SmtpServer = mailHost; System.Web.Mail.SmtpMail.Send(mmsg); } catch (Exception ex) { throw new Exception("邮箱异常！" + ex.Message); } }
3、多附件发送
/// <summary> /// 发送邮件，提供调用 /// </summary> /// <param name="strSendToList">收件人,多个收件人用做好事隔开</param> /// <param name="strSubject">主题</param> /// <param name="strBody">内容</param> /// <param name="strAttachmentsPath">附件路径</param> /// <param name="strOutErr">错误信息</param> /// <returns></returns> public bool SendMail(string strSendToList, string strSubject, string strBody, string[] arrAttachmentsPath, out string strOutErr) { //发送邮件服务器 string strHost = System.Configuration.ConfigurationManager.AppSettings["MailHost"].ToString(); //发件人地址 string strUserMail = System.Configuration.ConfigurationManager.AppSettings["MailSender"].ToString(); //发件人密码 string strUserPwd = System.Configuration.ConfigurationManager.AppSettings["MailSenderPwd"].ToString(); string ss = string.Empty; return SendMail(strHost, strUserMail, strUserPwd, strSendToList, strSubject, strBody, arrAttachmentsPath,out strOutErr); } /// <summary> /// 发邮件 /// </summary> /// <param name="strMailService">邮箱服务器</param> /// <param name="strSendMail">发件人邮箱</param> /// <param name="strSendMailPwd">发件人密码</param> /// <param name="strToList">收件人,多个收件人用做好事隔开</param> /// <param name="strSubject">主题</param> /// <param name="strMessage">邮件内容</param> /// <param name="AttachFile">附件路径</param> public bool SendMail(string strMailService, string strSendMail, string strSendMailPwd, string strToList, string strSubject, string strMessage, string[] AttachFile, out string strOutErr) { System.Net.Mail.SmtpClient client = new SmtpClient(strMailService); client.UseDefaultCredentials = false; client.Credentials = new System.Net.NetworkCredential(strSendMail, strSendMailPwd); client.DeliveryMethod = SmtpDeliveryMethod.Network; System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(strSendMail, strToList); message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = strSubject; message.Body = strMessage; message.IsBodyHtml = true; //在有附件的情况下添加附件 if (AttachFile != null && AttachFile.Length > 0) { foreach (string path in AttachFile) { var attachFile = new Attachment(path); message.Attachments.Add(attachFile); } } try { client.Send(message); strOutErr = string.Empty; } catch (Exception err) { strOutErr = err.Message; return false; } return true; }

调用：
StringBuilder sb= new StringBuilder(); sb.Append($@"{userInfo[0].UserTrueName} 你好！" + "\r\n\r\n"); sb.Append($@"车牌：{updateEntity.CarrierNo} 待审批，请尽快处理。" + "\r\n"); sb.Append($@"系统邮件，请勿回复！" + "\r\n\r\n"); Send("车辆备案审批", sb.ToString(), userInfo[0].Email);
