Answer 1

我认为Gmail SMTP端口应该是465，而不是587。

Answer 2

您是否尝试过评论该文章/与作者联系？

我想这里有两件事：

一个。你没有在catch块中做过任何事情。您应该考虑在catch块中跟随

catch(Exception ex){
DisplayMessage.Text = ex.Message;
DisplayMessage.Visible = true;
}

B中。检查您使用的Gmail帐户是否具有启用pop3 / imap的smtp。

试试这个

    protected void SendMail()
    {
        // any address where the email will be sending
        var toAddress = YourEmail.Text.ToString();
        //Password of your gmail address
        const string fromPassword = "Password";
        // Passing the values and make a email formate to display
        string subject = YourSubject.Text.ToString();
        string body = "From: " + YourName.Text + "\n";
        body += "Email: " + YourEmail.Text + "\n";
        body += "Subject: " + YourSubject.Text + "\n";
        body += "Question: \n" + Comments.Text + "\n";

        SmtpClient smtpClient = new SmtpClient();
        MailMessage message = new MailMessage();
        MailAddress fromAddress = new MailAddress("ml27.santos@gmail.com");
        smtpClient.Host = "smtp.gmail.com";
        smtpClient.Port = 587;
        smtpClient.UseDefaultCredentials = false;
        smtpClient.EnableSsl = true;
        smtpClient.Credentials = new System.Net.NetworkCredential("ml27.santos@gmail.com", fromPassword);
        message.From = fromAddress;
        message.To.Add(toAddress);
        message.Subject = subject;
        message.Priority = MailPriority.High;
        message.Body = body;
        message.IsBodyHtml = true;
        smtpClient.Send(message);
    }
