前言

本文主要给大家介绍了关于.NET发送邮件的相关内容，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。

注意：需要找到“POP3/SMTP服务”并开启，然后生成授权码，生成的授权码就是下面登入的密码。

关于POP3/SMTP服务是什么，大家可以参考这篇文章进行了解：//www.gxlcms.com/softjc/42323.html

的开启方法大家可以参考这篇文章：//www.gxlcms.com/diannaojichu/520949.html

示例代码：

/// <summary>
 /// 发送邮件
 /// </summary>
 /// <param name="to">收件人（多人由;隔开）</param>
 /// <param name="title">标题</param>
 /// <param name="content">内容</param>
 /// <param name="cc">抄送</param>
 /// <returns></returns>
 public string sendEmail(string to, string title, string content, string cc = "")
 {
 try
 {
 System.Net.Mail.MailMessage myMail = new System.Net.Mail.MailMessage();
 myMail.From = new System.Net.Mail.MailAddress("xxx@qq.com","xx通知", System.Text.Encoding.UTF8); //发件人地址，发件人姓名，编码
 string[] tos = to.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
 for (int i = 0; i < tos.Length; i++)
 {
 myMail.To.Add(new System.Net.Mail.MailAddress(tos[i]));
 }
 string[] ccs = cc.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);
 for (int i = 0; i < ccs.Length; i++)
 {
 myMail.CC.Add(new System.Net.Mail.MailAddress(ccs[i]));
 }
 myMail.Subject = title;
 myMail.SubjectEncoding = Encoding.UTF8;
 myMail.Body = content;
 myMail.BodyEncoding = Encoding.UTF8;
 myMail.IsBodyHtml = true;
 System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
 smtp.Host = "smtp.qq.com"; smtp.EnableSsl = true;
 smtp.UseDefaultCredentials = false;
 smtp.Credentials = new System.Net.NetworkCredential("xxx@qq.com", "password");
 smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
 smtp.Send(myMail);
 return "";
 }
 catch (Exception ee)
 {
 return ee.ToString();
 }
 }
