MailSmtp ms = new MailSmtp ("smtp.qq.com", "1215247044", "xxxx"); // optional parameter ms. setCC ("610262374@qq.com"); // CC can be multiple ms. setBC ("610262374@qq.com"); // BCC can be multiple ms. setIsHtml (true); // default value: true ms. setEncoding (System. text. encoding. UTF8); // The default format is UTF-8 ms. setIsSSL (true); // whether ssl encryption is set to false by default. // call the function bool isSuccess = ms. send ("1215247044@qq.com", "test", "610262374@qq.com", "Haha", "Haha", Server. mapPath ("~ /Test. dll "); // output Result Response. Write (ms. Result );
