如何通过asp.net内核中的Nlog将信息记录到多个单独的文件中？

<configuration>
  <configSections>
    <section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog"/>
  </configSections>
  <nlog>
    <targets>
      <!-- 定义多个目标 -->
      <target name="file1" xsi:type="File" fileName="log1.txt" layout="${longdate} ${level} ${message}" />
      <target name="file2" xsi:type="File" fileName="log2.txt" layout="${longdate} ${level} ${message}" />
    </targets>
    <rules>
      <!-- 定义规则，将日志记录到不同的目标 -->
      <logger name="*" minlevel="Info" writeTo="file1" />
      <logger name="*" minlevel="Error" writeTo="file2" />
    </rules>
  </nlog>
</configuration>

protected void Application_Start()
{
    // 初始化Nlog配置
    LogManager.LoadConfiguration();
}

private static Logger logger = LogManager.GetCurrentClassLogger();

protected void Page_Load(object sender, EventArgs e)
{
    try
    {
        // 记录Info级别的日志到file1目标
        logger.Info("This is an info message.");

        // 记录Error级别的日志到file2目标
        logger.Error("This is an error message.");
    }
    catch (Exception ex)
    {
        // 记录异常信息到file2目标
        logger.Error(ex, "An exception occurred.");
    }
}
