ASP.NET MVC - 如何处理发送电子邮件？

using MailKit.Net.Smtp;
using MimeKit;

public class EmailSender
{
    public static void SendEmail(string to, string subject, string body)
    {
        var message = new MimeMessage();
        message.From.Add(new MailboxAddress("发件人名称", "发件人邮箱地址"));
        message.To.Add(new MailboxAddress("收件人名称", to));
        message.Subject = subject;
        message.Body = new TextPart("plain")
        {
            Text = body
        };

        using (var client = new SmtpClient())
        {
            client.Connect("smtp.example.com", 587, false);
            client.Authenticate("用户名", "密码");
            client.Send(message);
            client.Disconnect(true);
        }
    }
}

public ActionResult SendEmail()
{
    EmailSender.SendEmail("收件人邮箱地址", "邮件主题", "邮件正文");
    return View();
}
