1.实现原理:
- 微软封装好的MailMessage类:主要处理发送邮件的内容(如:收发人地址、标题、主体、图片等等)
- 微软封装好的SmtpClient类:主要处理用smtp方式发送此邮件的配置信息(如:邮件服务器、发送端口号、验证方式等等)
- SmtpClient主要进行了三层的封装:Socket --> TcpClient --> SmtpClient
2.构建帮助工具类:
using System;using System.IO;using System.Net.Mail;using System.Net.Mime;public class MyEmail{ private MailMessage mMailMessage; //主要处理发送邮件的内容(如:收发人地址、标题、主体、图片等等) private SmtpClient mSmtpClient; //主要处理用smtp方式发送此邮件的配置信息(如:邮件服务器、发送端口号、验证方式等等) private int mSenderPort; //发送邮件所用的端口号(htmp协议默认为25) private string mSenderServerHost; //发件箱的邮件服务器地址(IP形式或字符串形式均可) private string mSenderPassword; //发件箱的密码 private string mSenderUsername; //发件箱的用户名(即@符号前面的字符串,例如:hello@163.com,用户名为:hello) private bool mEnableSsl; //是否对邮件内容进行socket层加密传输 private bool mEnablePwdAuthentication; //是否对发件人邮箱进行密码验证 ////// 构造函数 /// ///发件箱的邮件服务器地址 ///收件人地址(可以是多个收件人,程序中是以“;"进行区分的) ///发件人地址 ///邮件标题 ///邮件内容(可以以html格式进行设计) ///发件箱的用户名(即@符号前面的字符串,例如:hello@163.com,用户名为:hello) ///发件人邮箱密码 ///发送邮件所用的端口号(htmp协议默认为25) ///true表示对邮件内容进行socket层加密传输,false表示不加密 ///true表示对发件人邮箱进行密码验证,false表示不对发件人邮箱进行密码验证 public MyEmail(string server, string toMail, string fromMail, string subject, string emailBody, string username, string password, string port, bool sslEnable, bool pwdCheckEnable) { try { mMailMessage = new MailMessage(); mMailMessage.To.Add(toMail); mMailMessage.From = new MailAddress(fromMail); mMailMessage.Subject = subject; mMailMessage.Body = emailBody; mMailMessage.IsBodyHtml = true; mMailMessage.BodyEncoding = System.Text.Encoding.UTF8; mMailMessage.Priority = MailPriority.Normal; this.mSenderServerHost = server; this.mSenderUsername = username; this.mSenderPassword = password; this.mSenderPort = Convert.ToInt32(port); this.mEnableSsl = sslEnable; this.mEnablePwdAuthentication = pwdCheckEnable; } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } ////// 邮件的发送 /// public void Send() { try { if (mMailMessage != null) { mSmtpClient = new SmtpClient(); //mSmtpClient.Host = "smtp." + mMailMessage.From.Host; mSmtpClient.Host = this.mSenderServerHost; mSmtpClient.Port = this.mSenderPort; mSmtpClient.UseDefaultCredentials = false; mSmtpClient.EnableSsl = this.mEnableSsl; if (this.mEnablePwdAuthentication) { System.Net.NetworkCredential nc = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); //mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); //NTLM: Secure Password Authentication in Microsoft Outlook Express mSmtpClient.Credentials = nc.GetCredential(mSmtpClient.Host, mSmtpClient.Port, "NTLM"); } else { mSmtpClient.Credentials = new System.Net.NetworkCredential(this.mSenderUsername, this.mSenderPassword); } mSmtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; mSmtpClient.Send(mMailMessage); } } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } ////// 添加附件 /// ///附件的路径集合,以分号分隔 public void AddAttachments(string attachmentsPath) { try { string[] path = attachmentsPath.Split(';'); //以什么符号分隔可以自定义 Attachment data; ContentDisposition disposition; for (int i = 0; i < path.Length; i++) { data = new Attachment(path[i], MediaTypeNames.Application.Octet); disposition = data.ContentDisposition; disposition.CreationDate = File.GetCreationTime(path[i]); disposition.ModificationDate = File.GetLastWriteTime(path[i]); disposition.ReadDate = File.GetLastAccessTime(path[i]); mMailMessage.Attachments.Add(data); } } catch (Exception ex) { Console.WriteLine(ex.ToString()); } }}
3.控制台相关代码
static void Main(string[] args){ try { //smtp.163.com //string senderServerIp = "123.125.50.133"; //smtp.gmail.com //string senderServerIp = "74.125.127.109"; //smtp.qq.com string senderServerIp = "smtp.qq.com";//qq邮箱的smtp地址 //string senderServerIp = "smtp.sina.com"; string toMailAddress = "1277529182@qq.com";//收件人的邮箱地址 string fromMailAddress = "1277529182@qq.com";//发件人的邮箱地址 string subjectInfo = "Test";//主题 string bodyInfo = "This is test email";//内容 string mailUsername = "1277529182";//邮箱的用户名 string mailPassword = "111"; //发送邮箱的密码(如果是QQ邮箱需要配置客户端密码) string mailPort = "25";//端口 //string attachPath = "E:\\123123.txt; E:\\haha.pdf";//添加的附件 MyEmail email = new MyEmail(senderServerIp, toMailAddress, fromMailAddress, subjectInfo, bodyInfo, mailUsername, mailPassword, mailPort, true, true); //email.AddAttachments(attachPath); email.Send(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); }}
4.需要身份验证的邮箱SMTP,例如QQ邮箱,则需要配置客户端密码:
开启SMTP服务最后使用生成的授权码填入到【发送邮箱的密码】
