Due to the official library's inadequate support for ports 465 and 587, it is recommended to use MailKit, as shown in the following example.
using System;
using MimeKit;
using MailKit.Net.Smtp;
using MailKit.Security;

// This code example uses MailKit (MIT License: https://github.com/jstedfast/MailKit)

class Program
{
    static void Main()
    {
        try
        {   
            // Sender address created in the console
            string fromEmail = "test@example.com";
            // SMTP password set in the console
            string password = "your password";
            string toEmail = "to@example.com";
            string smtpHost = "sg-smtp.qcloudmail.com";
            int smtpPort = 465; 
            var message = new MimeMessage();
            message.From.Add(new MailboxAddress("", fromEmail));
            message.To.Add(new MailboxAddress("", toEmail));
            message.Subject = "Test Email with HTML Content";
            message.Body = new TextPart("html")
            {
                Text = @"
                    <html>
                        <body>
                            <h1 style='color:blue;'>Hello!</h1>
                            <p>This is a <b>HTML test email</b> from <i>Tencent Cloud SES</i>.</p>

                    </html>"
            };

            using (var client = new SmtpClient())
            {
                client.Connect(smtpHost, smtpPort, SecureSocketOptions.SslOnConnect);
                client.Authenticate(fromEmail, password);
                client.Send(message);
                client.Disconnect(true);
            }

            Console.WriteLine("Email sent successfully.");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error: {ex.Message}");
        }
    }
}
