如何通过从NLog邮件目标发送电子邮件附加文件或文件？

<target name="mail" xsi:type="Mail"
        smtpServer="smtp.example.com"
        smtpPort="587"
        smtpAuthentication="Basic"
        smtpUsername="your-email@example.com"
        smtpPassword="your-password"
        from="your-email@example.com"
        to="recipient@example.com"
        subject="NLog Log Files"
        body="Attached log files are included."
        html="true"
        addAttachment="true"
        encoding="UTF-8"
        enableSsl="true"
        layout="${message}" />

<rules>
  <logger name="*" minlevel="Error" writeTo="mail" />
</rules>

var logger = LogManager.GetCurrentClassLogger();
var logEvent = new LogEventInfo(LogLevel.Info, logger.Name, "Log message with attachment");
logEvent.Attachments.Add(new Attachment("path/to/file.txt"));
logger.Log(logEvent);
