1. 实现功能:

  通过程序自动发送邮件。使用QQ邮箱(个人/企业)或阿里云邮箱(企业)。

 

2. 编码过程中的尝试结果:

  2.1 测试配置:见3.1 app.config配置

  2.2 测试结果

C# 通过QQ邮箱和阿里云邮箱自动发送邮件(对System.Web.Mail与System.Net.Mail的测试)

 

  

3. 代码实现

  3.1 app.config配置

    3.1.1 QQ邮箱配置

1 <connectionStrings>     2   <add name="MailServerIP" connectionString="smtp.exmail.qq.com" /> 3     <add name="MailServerPort" connectionString="465" /> 4     <add name="fromMailAddress" connectionString="xxx@yyy.com" /> 5     <add name="toMailAddress" connectionString="xxx2@yyy.com"/> 6     <add name="mailUsername" connectionString="usernamexxx" /> 7     <add name="mailPassword" connectionString="passwordxxx" /> 8     <add name="ccMailAddress" connectionString="usercc@yyy.com" /> 9 </connectionStrings>
注:若是QQ个人邮箱,则mailPassword需配置成授权码

    3.1.2 阿里云邮箱配置

1 <connectionStrings>   2   <add name="MailServerIP" connectionString="smtp.qiye.aliyun.com" /> 3   <add name="MailServerPort" connectionString="25" /> 4   <add name="fromMailAddress" connectionString="xxx@yyy.com" /> 5   <add name="toMailAddress" connectionString="xxx1@yyy.com"/> 6   <add name="mailUsername" connectionString="usernamexxx" /> 7   <add name="mailPassword" connectionString="passwordxxx" /> 8   <add name="ccMailAddress" connectionString="usercc@yyy.com" /> 9 </connectionStrings>

 

  3.2 调用

1 public void EventOccured(string EventID) 2 { 3     string subjectInfo = "一些要发送邮件的事件发生咯"; 4     string bodyInfo = "<p style ="font-size: 10pt">Hi,all</p>"; 5     bodyInfo += "<p style ="font-size: 10pt;color:red">事件:" + EventID + "已经发生,请注意监控。</p>"; 6     bodyInfo += "<p style ="font-size: 10pt">以上内容为系统自动发送,请勿直接回复,谢谢。</p>"; 7  8     SendMailHelper.Sendmail_(subjectInfo, bodyInfo); 9 }

 1 public static void Sendmail_(string subjectInfo, string bodyInfo)  2 {  3     try  4     {  5         string senderServerIp = ConfigurationManager.ConnectionStrings["MailServerIP"].ConnectionString;  6         string toMailAddress = ConfigurationManager.ConnectionStrings["toMailAddress"].ConnectionString;  7         string fromMailAddress = ConfigurationManager.ConnectionStrings["fromMailAddress"].ConnectionString;  8         string mailUsername = ConfigurationManager.ConnectionStrings["mailUsername"].ConnectionString;  9         string mailPassword = ConfigurationManager.ConnectionStrings["mailPassword"].ConnectionString; 10         string mailPort = ConfigurationManager.ConnectionStrings["MailServerPort"].ConnectionString; 11         string cc = ConfigurationManager.ConnectionStrings["ccMailAddress"].ConnectionString; 12  13         MyEmail email = new MyEmail(senderServerIp, toMailAddress, fromMailAddress, subjectInfo, bodyInfo, mailUsername, mailPassword, mailPort, cc, true, false);  //注: aliyun需将最后参数改为:false,true 14         email.Send(); 15     } 16     catch (Exception ex) 17     { 18         Console.WriteLine(ex.ToString()); 19     } 20 }

 

  3.3 具体实现

  3.3.1 QQ邮箱:使用System.Web.Mail

 1 private System.Web.Mail.MailMessage mMessage;  2   3 public MyEmail(string server, string toMail, string fromMail, string subject, string emailBody, string username, string password, string port,string cc, bool sslEnable, bool pwdCheckEnable)  4 {  5     try  6     {  7         //for System.Web.Mail: QQ MAIL  8         mMessage = new System.Web.Mail.MailMessage();  9         mMessage.Priority = System.Web.Mail.MailPriority.Normal; 10         mMessage.From = fromMail; 11         mMessage.To = toMail; 12         mMessage.Cc = cc; 13         mMessage.Subject = subject; 14         mMessage.BodyFormat = System.Web.Mail.MailFormat.Html; 15         mMessage.BodyEncoding = Encoding.UTF8; 16         mMessage.Body = emailBody; 17         mMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //basic authentication 18         mMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", fromMail); //set your username here 19         mMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", password); //set your password here 20         mMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", port);//set port 21         mMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", sslEnable);//set is ssl 22         System.Web.Mail.SmtpMail.SmtpServer = server; 23     } 24     catch (Exception ex) 25     { 26     } 27 }

 1 public void Send()  2 {  3     try  4     {  5         //for System.Web.Mail  6         if (mMessage != null)  7         {  8             System.Web.Mail.SmtpMail.Send(mMessage);  9         } 10     } 11     catch (Exception ex) 12     { 13         Console.WriteLine(ex.ToString()); 14     } 15 }

 

  3.3.2 阿里云邮箱:使用System.Net.Mail
