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）

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

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

22         mMailMessage.Priority = MailPriority.Normal;
23         if (!string.IsNullOrEmpty(cc))
24             mMailMessage.CC.Add(cc);
25         this.mSenderServerHost = server;
26         this.mSenderUsername = fromMail;
27         this.mSenderPassword = password;
28         this.mSenderPort = Convert.ToInt32(port);
29         this.mEnableSsl = sslEnable;
30         this.mEnablePwdAuthentication = pwdCheckEnable;
31     }
32     catch (Exception ex)
33     {
34         Console.WriteLine(ex.ToString());
35     }

20             }
21             else
