.NET Core 中的 NLog 不存档日志文件

如何解决.NET Core 中的 NLog 不存档日志文件

我有 NLog，它正在登录我的日志文件，但它没有存档日志文件，我仍然在日志文件中看到昨天的日志，它们没有存档，而且我没有看到为存档创建的新文件。下面是配置代码：

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      autoReload="true" internalLogLevel="Info"
      internalLogFile="C:\temp\EMCS\ItemAPI\ItemAPI-internal-nlog.txt">

  <!-- enable asp.net core layout renderers -->
  <extensions>
    <add assembly="NLog.Web.AspNetCore"/>
  </extensions>

  <variable name="logDirectory" value="C:\temp\EMP\ITEM"/>
  <targets>
      <!-- write logs to file  -->
       <target xsi:type="File"
       name="file"
       archiveEvery="Day"
       archiveFileName = "ItemAPI-{########}.log"
       archiveNumbering = "Date"
       archiveDateFormat = "yyyyMMdd"
       maxArchiveFiles = "4"
       fileName="${logDirectory}\ItemAPI.log"
       layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${aspnet-user-identity}|${machinename}|${processname}|${message} ${exception:format=tostring}" />
    </target>
  </targets>

  <rules>
    <!--Skip non-critical Microsoft logs and so log only own logs-->
    <logger name="Microsoft.*" maxlevel="Info" final="true" />
    <logger name="*" minlevel="Trace" writeTo="file" />
  </rules>
</nlog>

我是否遗漏了文件日志配置中的任何内容？为什么我在运行解决方案时没有看到档案被创建并且我的文件日志没有得到清理。
