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(); }
