使用 log4net 为每个线程 (Parallel.For) 提供单独的日志文件

Question

我需要为每个使用 log4net 的线程创建单独的日志文件。 我正在阅读多个邮箱，并希望在单个文件中通过电子邮件发送邮箱的信息和附件信息。

EmailMaster objEmailMaster = new EmailMaster();
List<MailboxConfiguration> lstMailBoxConfiguration = objEmailMaster.GetMailBoxInformation();

Parallel.For(0, lstMailBoxConfiguration.Count, i =>
{                       
    log.Debug("MailBox reading");    
    objEmailMaster.ReadAndDownloadEmails(lstMailBoxConfiguration[i]);                 
});

Answer 1

您可以像在这个概念验证中那样按线程使用日志字典：

var ThreadedLogs = new Dictionary<Thread, Log>();

Action<Thread, string> Log = (thread, text) =>
{
  Monitor.Enter(ThreadedLogs);
  if ( !ThreadedLogs.ContainsKey(thread) )
    ThreadedLogs.Add(thread, new Log());
  ThreadedLogs[thread].Debug(text);
  Monitor.Exit(ThreadedLogs);
};

Parallel.For(0, lstMailBoxConfiguration.Count, i =>
{
  Log(Thread.CurrentThread, "MailBox reading");
  objEmailMaster.ReadAndDownloadEmails(lstMailBoxConfiguration[i]);
});

ThreadedLogs.Clear();
