在贴代码之前,首先需要给QQ邮箱开服务IMAP/SMTP服务,详细开通方法见 "开通方法"(可能需要发送收费短信,所以只要开通这一个服务就好了)。
这边主要就是为了一个服务的授权码,如下图:
服务开好之后,直接上代码了(一个邮件帮助类):
using System; using System.Collections.Generic; using System.Linq; using System.Net.Mail; using System.Net.Mime; using System.Text; namespace Mail { public class SendMail { private MailMessage mailMessage; private SmtpClient smtpClient; private string password;//发件人密码 /// <summary> /// 设置MailMessage的实例 /// </summary> /// <param name="To">收件人地址</param> /// <param name="From">发件人地址</param> /// <param name="Body">邮件正文</param> /// <param name="Title">邮件的主题</param> /// <param name="Password">发件人密码</param> public SendMail(string[] To, string From, string Body, string Title, string Password) { mailMessage = new MailMessage(); foreach (var item in To) { mailMessage.To.Add(item); } mailMessage.From = new System.Net.Mail.MailAddress(From); mailMessage.Subject = Title; mailMessage.Body = Body; mailMessage.IsBodyHtml = true; mailMessage.BodyEncoding = System.Text.Encoding.UTF8; mailMessage.Priority = System.Net.Mail.MailPriority.Normal; this.password = Password; } /// <summary> /// 添加附件 /// </summary> public void Attachments(string Path) { string[] path = Path.Split(','); Attachment data; ContentDisposition disposition; for (int i = 0; i < path.Length; i++) { data = new Attachment(path[i], MediaTypeNames.Application.Octet);//实例化附件 disposition = data.ContentDisposition; disposition.CreationDate = System.IO.File.GetCreationTime(path[i]);//获取附件的创建日期 disposition.ModificationDate = System.IO.File.GetLastWriteTime(path[i]);//获取附件的修改日期 disposition.ReadDate = System.IO.File.GetLastAccessTime(path[i]);//获取附件的读取日期 mailMessage.Attachments.Add(data);//添加到附件中 } } /// <summary> /// 异步发送邮件 /// </summary> /// <param name="CompletedMethod"></param> public void SendAsync(SendCompletedEventHandler CompletedMethod) { if (mailMessage != null) { smtpClient = new SmtpClient(); smtpClient.EnableSsl = true;// 指定 System.Net.Mail.SmtpClient 是否使用安全套接字层 (SSL) 加密连接,必须在实例身份前面设置 smtpClient.UseDefaultCredentials = false; smtpClient.Credentials = new System.Net.NetworkCredential(mailMessage.From.Address, password);//设置发件人身份的票据 smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; smtpClient.Host = "smtp." + mailMessage.From.Host; smtpClient.SendCompleted += new SendCompletedEventHandler(CompletedMethod);//注册异步发送邮件完成时的事件 smtpClient.SendAsync(mailMessage, mailMessage.Body); } } /// <summary> /// 发送邮件 /// </summary> public void Send() { if (mailMessage != null) { using (smtpClient = new SmtpClient()) { smtpClient.EnableSsl = true;// 指定 System.Net.Mail.SmtpClient 是否使用安全套接字层 (SSL) 加密连接,必须在实例身份前面设置 smtpClient.UseDefaultCredentials = false; smtpClient.Credentials = new System.Net.NetworkCredential(mailMessage.From.Address, password);//设置发件人身份的票据 smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; smtpClient.Host = "smtp." + mailMessage.From.Host; smtpClient.Send(mailMessage); mailMessage.Attachments.Dispose(); } } } } }
调用方法如下:
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Mail { class Program { static void Main(string[] args) { string[] toArr = { "1234567890@qq.com" }; var sbSql=new System.Text.StringBuilder(); sbSql.Append("邮件内容"); SendMail sendmail = new SendMail(toArr, "0123456789@qq.com", sbSql.ToString(), "测试", "QQ邮箱服务授权码"); sendmail.Send(); } } }
这边的QQ邮箱服务授权码,就是上面开通的IMAP/SMTP服务的16位授权码。
