補充 :
如果想要自訂參數 ex.${event-context:item=Name}
程式中記得自訂log level 與參數即可
private static void WriteLog(string msg) { LogEventInfo ei = new LogEventInfo(NLog.LogLevel.Trace, "", ""); ei.Properties["Name"] = Guid.NewGuid(); ei.Properties["msg"] = msg; logger.Log(ei); }
config 加入 event-context 參數即可
<target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}/${event-context:item=appName}.log" layout="${longdate} |${uppercase:${level}}| ${event-context:item=msg}" /> </targets>
