log4net-仅针对一个记录器获取附加程序 [英] log4net - getting appenders specific to only one logger

问题描述

我正在寻找一种将所有附加程序附加到一个记录器实例的方法.

I'm looking for a way to get all appenders attached to one logger instance.

我尝试过:

Hierarchy hierarchy = LogManager.GetRepository() as Hierarchy;
hierarchy.GetAppenders()

根据文档，这将返回当前配置的所有记录器的所有附加器.

as per documentation this returns all appenders for all loggers currently configured.

当我尝试此操作时:

LogManager.GetLogger("MyLoggerName").Logger.Repository.GetAppenders();

我得到相同的结果.

我只想检索附加到一个记录器的附加器(在这种情况下为"MyLoggerName")

I would like to retrieve only appenders attached to one logger ("MyLoggerName" in this case)

我在哪里错了?

推荐答案

调用以下代码时

LogManager.GetLogger("MyLoggerName").Logger.Repository.GetAppenders();

实际上，您要查询与hierarchy.GetAppenders()完全相同的数据，因为Hierarchy继承了实现了ILoggerRepository(由Logger.Repository返回的类型)的LoggerRepositorySkeleton.

you are in fact asking the exact same data as hierarchy.GetAppenders() because Hierarchy inherits LoggerRepositorySkeleton, which implements ILoggerRepository, the type returned by Logger.Repository.

但是，您可以使用Hierarchy命名空间中的Logger类来获取第一级"附加程序的列表:

You can however get the list of "first level" appenders by using the Logger class that lives in the Hierarchy namespace:

var h = LogManager.GetRepository() as Hierarchy;
var l = h.GetLogger("MyLoggerName", h.LoggerFactory);
// do something with the l.Appenders property

您将不得不处理诸如bufefring或从那里过滤追加程序之类的特殊情况

You will have to handle special cases like bufefring or filtering appenders from there
