c#代码发送邮件(包括个人邮箱和企业邮箱)

个人邮箱如下：

		SmtpClient client = new SmtpClient("smtp.163.com");
        client.UseDefaultCredentials = false;
        client.EnableSsl = true;
        ///个人邮箱填写的是用户名和授权码，其中授权码，需要自己登录邮箱进行设置，成功设置后，会弹出授权码
        
        client.Credentials = new NetworkCredential("username", "authcode");//163邮箱
        MailAddress from = new MailAddress("[email protected]");
        MailAddress to = new MailAddress("[email protected]");
        MailMessage myMail = new MailMessage(from, to);


        myMail.Subject = "这是x发来163的邮件";

        myMail.Body = "试试功能";

        client.Send(myMail);

企业邮箱跟个人邮箱不一样，企业邮箱没有设置授权码的地方，企业邮箱是通过用户名和密码进行发送的，不过在发送前，需要添加一段话，如下：
ServicePointManager.ServerCertificateValidationCallback =
delegate (Object obj, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) { return true; };

完整的代码如下

		SmtpClient client = new SmtpClient();
        client.UseDefaultCredentials = false;
        client.EnableSsl = true;
        client.Host = "hikml5.hikvision.com.cn";
        client.Credentials = new NetworkCredential("username", "password");
        client.DeliveryMethod = SmtpDeliveryMethod.Network;


        MailAddress from = new MailAddress("[email protected]");
        MailAddress to = new MailAddress("[email protected]");
        MailMessage myMail = new MailMessage(from, to);


        myMail.Subject = "这是x发来hikvision的邮件";

        myMail.Body = "试试功能";

        ServicePointManager.ServerCertificateValidationCallback =
delegate (Object obj, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) { return true; };

        client.Send(myMail);
