c#通过126邮箱自动发送 微信端实现QQ邮箱邮件提醒

一、首先开启126邮箱的SMTP服务，需要短信验证，设置邮箱密码等操作。详细操作：/article/17bd8e526ddb4185aa2bb852.html

二、微信端设置开启QQ邮箱提醒，具体操作：/touch/faq/150612YrMBvY150612YN3mUz.html

开启QQ邮箱提醒。

三、发送邮箱为126邮箱，接收邮箱为QQ邮箱。

public void sxSendEmail(string mailSubject, string mailContent, string tostr){ // 设置发送方的邮件信息,例如使用网易的smtpArrayList userlist = new ArrayList();StreamReader objReader = new StreamReader("userlist.txt");string sLine = "111";// ArrayList arrText = new ArrayList();while (sLine != null){sLine = objReader.ReadLine();if (sLine != null)userlist.Add(sLine);}objReader.Close();string smtpServer = userlist[0].ToString();// ""; //SMTP服务器string mailFrom = userlist[1].ToString();// "xxx@"; //登陆用户名string userPassword = userlist[2].ToString();//"xxx";//登陆密码// string recipientsDisplayName = "111111";// 邮件服务设置SmtpClient smtpClient = new SmtpClient();smtpClient.DeliveryMethod = work;//指定电子邮件发送方式smtpClient.Host = smtpServer; //指定SMTP服务器smtpClient.Credentials = new workCredential(mailFrom, userPassword);//用户名和密码// MailAddress from = new MailAddress(mailFrom, "xxx@");// 发送邮件设置 MailMessage mailMessage = new MailMessage(); // 发送人和收件人// mailMessage.From.Address = "xxx@";// mailMessage.From.DisplayName = "xxx@";mailMessage.From = new MailAddress(mailFrom, userlist[1].ToString());// for(int i=0;i<maillist.Count;i++)mailMessage.To.Add(tostr);//(maillist[i].ToString());mailMessage.Subject = mailSubject;//主题mailMessage.Body = mailContent;//内容mailMessage.BodyEncoding = Encoding.UTF8;//正文编码mailMessage.IsBodyHtml = true;//设置为HTML格式mailMessage.Priority = MailPriority.Low;//优先级try{smtpClient.Send(mailMessage); // 发送邮件sxWriteForTxt(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToLongTimeString() + tostr + mailSubject + mailContent + "发送成功");}catch (SmtpException ex){sxWriteForTxt(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToLongTimeString() + tostr + mailSubject + mailContent + ex.ToString() + "发送邮件出错");}}

四、定时检测，本次检测与上一次检测不同，则向指定QQ邮箱发送提醒邮件，从而实现微信提醒。

string resultstr = “111111111111111111111111111111111111111111111111111111111111111111111111111111111”;//默认检测的81路端口信号都为正常状态1（UP）。不正常状态为2（DOWN）

private void timer2_Tick(object sender, EventArgs e){try{string tempstr = "";string sxstr = readTxt("sxoid.txt");string sxplace=readTxt("sxplace.txt");char[] chs={','};string[] places = sxplace.Split(chs, StringSplitOptions.RemoveEmptyEntries);string[] nums = sxstr.Split(chs, StringSplitOptions.RemoveEmptyEntries);OctetString community = new OctetString("zjgdread");AgentParameters param = new AgentParameters(community);param.Version = SnmpVersion.Ver1;for (int i = 2; i < nums.Length; i++){IpAddress agent = new IpAddress(nums[0].ToString());//("10.1.92.252");// Construct target UdpTarget target = new UdpTarget((IPAddress)agent, 161, 200, 1);// Pdu class used for all requests Pdu pdu = new Pdu(PduType.Get);// pdu.VbList.Add("1.3.6.1.2.1.2.2.1.2." + nums[i].ToString()); //interface name // pdu.VbList.Add("1.3.6.1.2.1.2.2.1.5." + nums[i].ToString()); //interface speed// pdu.VbList.Add("1.3.6.1.2.1.31.1.1.1.18." + nums[i].ToString()); //ifalias//pdu.VbList.Add(nums[1].ToString() + nums[i].ToString()); //interface oper statusSnmpV1Packet result = null;try{// Make SNMP request result = (SnmpV1Packet)target.Request(pdu, param);}catch (Exception err){sxWriteForTxt(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToLongTimeString() + err.ToString());result = null;}if (result != null){// ErrorStatus other then 0 is an error returned by // the Agent - see SnmpConstants for error definitions if (result.Pdu.ErrorStatus != 0){// agent reported an error with the request WriteForTxt(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToLongTimeString() + "Error in SNMP reply");}else{// d1 = double.Parse(result.Pdu.VbList[0].Value.ToString()) / 10.0;// d2 = double.Parse(result.Pdu.VbList[1].Value.ToString()) / 10.0;//numstr = d1.ToString() + "," + d2.ToString();/* dr[1] = result.Pdu.VbList[0].Value.ToString();dr[2] = result.Pdu.VbList[1].Value.ToString();dr[3] = GetChsFromHex(result.Pdu.VbList[2].Value.ToString());dr[4] = result.Pdu.VbList[3].Value.ToString();dr[5] = DateTime.Now.ToLongTimeString();* */tempstr = tempstr + result.Pdu.VbList[0].Value.ToString();}}else{// Label28.Text = Label28.Text + string.Format("No response received from SNMP agent. \r\n");sxWriteForTxt(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToLongTimeString() + "No response received from SNMP agent. \r\n");}// dt.Rows.Add(dr);target.Dispose();}if (tempstr == resultstr){textBox5.Text = DateTime.Now.ToLongTimeString();}else{string ss = "";if (tempstr.Length == 81){int j = 0;for (int i = 0; i < places.Length; i++){j = i * 3;ss = ss + places[i] + tempstr[j].ToString() + tempstr[j+1].ToString() + tempstr[j+2].ToString();}}else{ss = "hw error";}resultstr = tempstr;for (int i = 0; i < sxmaillist.Count; i++){sxSendEmail(i.ToString() + "hw alarm", i.ToString() + ss, sxmaillist[i].ToString());System.Threading.Thread.Sleep(1000);}}//dataGridView1.DataSource = ds.Tables[0];// GridView3.DataSource = ds.Tables[0];// GridView3.DataBind();}catch (Exception err){sxWriteForTxt(DateTime.Now.ToLongDateString() + " " + DateTime.Now.ToLongTimeString() + err.ToString());//WriteForTxt( + err.ToString());}}

总结：利用C#程序设计通过SNMP协议，定时读取H3C交换机端口信息，当检测到端口出现异常时，会发送邮件在微信上提醒，从而实现网管中的消息提醒功能，在长距离链路传输中，具有一定价值。
