如何使用NLog登录多个目标？

<?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="Off"
      internalLogFile="c:\temp\nlog-internal.log">

  <targets>
    <target name="file" xsi:type="File" fileName="c:\temp\log.txt" />
    <target name="database" xsi:type="Database" connectionString="Data Source=your_database;Initial Catalog=your_catalog;User ID=your_user;Password=your_password;"
            commandText="INSERT INTO LogTable (Timestamp, Level, Message) VALUES (@time_stamp, @level, @message);" />
  </targets>

  <rules>
    <logger name="*" minlevel="Trace" writeTo="file" />
    <logger name="*" minlevel="Error" writeTo="database" />
  </rules>
</nlog>

using NLog;

class Program
{
    private static Logger logger = LogManager.GetCurrentClassLogger();

    static void Main(string[] args)
    {
        logger.Trace("This is a trace message");
        logger.Debug("This is a debug message");
        logger.Info("This is an info message");
        logger.Warn("This is a warning message");
        logger.Error("This is an error message");
        logger.Fatal("This is a fatal message");

        // Other code...

        LogManager.Shutdown();
    }
}
