调用发送邮件的方法:

 static void Main(string[] args)
        {
            //获得各种参数，不需要的用空字符串
            string path = Directory.GetCurrentDirectory();
            string file = path + @"\Excel.xlsx"; //附件1
            string file2 = path + @"\Excel2.xlsx";//附件2
            string smtpServer = "smtp.163.com";//163邮箱的smtp服务器 
            int port = 25;//端口
            string mailFrom = "******@163.com";//发件人邮箱 
            string pwd = "*********";//密码
            string mailTo = "123@163.com,456@qq.com";//收件人邮箱,多个用户用逗号隔开
            string mailCC = "";//抄送人,多个用户用逗号隔开
            string mailBcc = "";//密送
            string mailSubject = "测试邮件";//主题
            string mailContent = "HI,这是我发给你的一个测试邮件";//内容
            string ah = file+","+file2; //附件-文件路径
            if (EmailHelper.SendEmail(smtpServer, port, mailFrom, pwd, mailTo, mailCC, mailBcc, mailSubject, mailContent, ah) == true)
            {
                Console.WriteLine("发送成功!");
            }
            else
                Console.WriteLine("发送失败");
           
            Console.ReadKey();
        }

 

注意:

• 确认发件人的邮箱已开通smtp;
• 对应邮箱的smtp填写正确，例:126邮箱:smtp@126.com
• 对应的邮箱SendEmail 中是否要使用SSL加密连接
