使用MailMessage发送邮件
SmtpClient smtp = new SmtpClient(); //实例化一个SmtpClient smtp.DeliveryMethod = SmtpDeliveryMethod.Network; //将smtp的出站方式设为 Network smtp.EnableSsl = false;//smtp服务器是否启用SSL加密 smtp.Host = "smtp.163.com"; //指定 smtp 服务器地址 smtp.Port = 25; //指定 smtp 服务器的端口,默认是25,如果采用默认端口,可省去 //如果你的SMTP服务器不需要身份认证,则使用下面的方式,不过,目前基本没有不需要认证的了 smtp.UseDefaultCredentials = true; //如果需要认证,则用下面的方式 smtp.Credentials = new NetworkCredential("a@163.com", "****"); MailMessage mm = new MailMessage(); //实例化一个邮件类 mm.Priority = MailPriority.High; //邮件的优先级,分为 Low, Normal, High,通常用 Normal即可 mm.From = new MailAddress("b@163.com", "真有意思测试", Encoding.GetEncoding(936)); //收件方看到的邮件来源; //第一个参数是发信人邮件地址 //第二参数是发信人显示的名称 //第三个参数是 第二个参数所使用的编码,如果指定不正确,则对方收到后显示乱码 //936是简体中文的codepage值 //注:上面的邮件来源,一定要和你登录邮箱的帐号一致,否则会认证失败 mm.ReplyTo = new MailAddress("b@163.com", "我的接收邮箱", Encoding.GetEncoding(936)); //ReplyTo 表示对方回复邮件时默认的接收地址,即:你用一个邮箱发信,但却用另一个来收信 //上面后两个参数的意义, 同 From 的意义 //mm.CC.Add("a@163.com,b@163.com,c@163.com"); //邮件的抄送者,支持群发,多个邮件地址之间用 半角逗号 分开 //当然也可以用全地址,如下: mm.CC.Add(new MailAddress("c@163.com", "抄送者A", Encoding.GetEncoding(936))); //mm.CC.Add(new MailAddress("b@163.com", "抄送者B", Encoding.GetEncoding(936))); //mm.CC.Add(new MailAddress("c@163.com", "抄送者C", Encoding.GetEncoding(936))); //mm.Bcc.Add("d@163.com,e@163.com"); //邮件的密送者,支持群发,多个邮件地址之间用 半角逗号 分开 //当然也可以用全地址,如下: //mm.CC.Add(new MailAddress("d@163.com", "密送者D", Encoding.GetEncoding(936))); //mm.CC.Add(new MailAddress("e@163.com", "密送者E", Encoding.GetEncoding(936))); //mm.Sender = new MailAddress("xxx@xxx.com", "邮件发送者", Encoding.GetEncoding(936)); //可以任意设置,此信息包含在邮件头中,但并不会验证有效性,也不会显示给收件人 //说实话,我不知道有啥实际作用,大家可不理会,也可不写此项 //mm.To.Add("g@163.com,h@163.com"); //邮件的接收者,支持群发,多个地址之间用 半角逗号 分开 //当然也可以用全地址添加 mm.To.Add(new MailAddress("g@163.com", "接收者g", Encoding.GetEncoding(936))); //mm.To.Add(new MailAddress("h@163.com", "接收者h", Encoding.GetEncoding(936))); mm.Subject = "这是邮件标题-测试"; //邮件标题 mm.SubjectEncoding = Encoding.GetEncoding(936); // 这里非常重要,如果你的邮件标题包含中文,这里一定要指定,否则对方收到的极有可能是乱码。 // 936是简体中文的pagecode,如果是英文标题,这句可以忽略不用 mm.IsBodyHtml = true; //邮件正文是否是HTML格式 mm.BodyEncoding = Encoding.GetEncoding(936); //邮件正文的编码, 设置不正确, 接收者会收到乱码 mm.Body = "<font color=\"red\">邮件测试,呵呵</font>"; //邮件正文 mm.Attachments.Add(new Attachment(@"c:\d\1.doc", System.Net.Mime.MediaTypeNames.Application.Rtf)); //添加附件,第二个参数,表示附件的文件类型,可以不用指定 //可以添加多个附件 //mm.Attachments.Add(new Attachment(@"d:b.doc")); smtp.Send(mm); //发送邮件,如果不返回异常, 则大功告成了。 }
