[HttpPost]
public IHttpActionResult SendEmail(string to, string subject, string body)
{
    // 在这里编写发送电子邮件的代码
    return Ok();
}

[HttpPost]
public IHttpActionResult SendEmail(string to, string subject, string body)
{
    using (var client = new SmtpClient())
    {
        var message = new MailMessage();
        message.To.Add(new MailAddress(to));
        message.Subject = subject;
        message.Body = body;

        client.Send(message);
    }

    return Ok();
}
