使用log4net的每条消息的新文件

Question

I'm using log4net to trace application errors and debugging information, all of that goes into one big file and is working fine.

But I'm also want to create a separate log4net appender which will be used to dump incoming messages to disk. These will be in a separate directory and I want each call to log.Info to be written to a new file, preferably with a timestamp in the filename.

That way I can easily bring up the specific message that was sent to my component at a given timestamp.

Can this be done through configuration?

Would something like this work for you?

private void LogFile(string logFileName, string message, Exception ex)
{
    log4net.ThreadContext.Properties["Version"] = "1";
    log4net.GlobalContext.Properties["LogName"] = logFileName;

    ILog logger = LogManager.GetLogger("DeIdentifyDicom");

    log4net.Config.XmlConfigurator.Configure();

    if (ex != null)
    {
        logger.Fatal(message, ex);
    }
    else
    {
        logger.Fatal(message);
    }
}

how do I define log file at run time?
