我赞同上面的方法，并且更喜欢nLog。Entlib不必要地膨胀。

有一件事总是让我与Log4net忘记添加以下到全局。Asax初始化组件:

log4net.Config.XmlConfigurator.Configure();

我认为一般的共识是nlog更容易配置和使用。不过，两者都很有能力。

根据我的经验，SmartInspect优于NLog和log4net。

它非常容易使用，文档很棒，您可以使用交互式日志查看器查看和过滤以前记录的消息，这是一个巨大的现实优势。

我喜欢的一件事是数据的标签视图，就像Chrome中的浏览器标签。每个选项卡都可以提供不同的日志过滤视图。

正如我注意到的那样，log4net在应用程序运行的整个过程中都会锁定它们的输出文件，因此不能删除它们。除此之外，它们是相似的。

所以我更喜欢NLog。

您也可以考虑Microsoft企业库日志记录块。它有很好的设计师。

我最近被要求为一个即将到来的项目“创建一些登录的原型”。我没有任何日志框架的经验。我花了几天时间在Log4Net、NLog和Enterprise Library上研究、浏览教程、制作玩具应用程序等。3-4周后再回来，将它们整合成一个完整的演示版本。希望这些对你们有用。

我对我们项目的建议是:

使用日志facade(例如Common。日志，SimpleLoggingFacade)以避免直接依赖。 如果我们最终要将企业库用于其他功能，那么也要将其用于日志记录。 如果我们最终要使用依赖于Log4Net的东西，那么就使用Log4Net。 如果以上都不是，请使用NLog。我更喜欢这样。

这是基于以下发现(意见!):

All 3 frameworks are capable and can do some sophisticated things. We want a quality solution, but frankly don't need ultra high performance or 60 types of event sinks. All 3 have very similar basic concepts. Each has its own cool tricks, like really advanced routing, or dynamic log filenames, file truncating, etc. All 3 are pretty well documented in their own way. For a complete newb like me, they were all a little awkward initially. No drastic differences here for the basics. I got over it. When revisiting things a few weeks later, NLog was clearly the easiest to resume. I needed very little brush up on it. With Log4Net, I had to revisit a few online examples to get going. With EntLib, I gave up and did the tutorials all over again from scratch - I was totally lost. I couldn't figure out how to get EntLib to do some things like log to the database. It might be easy, but it was beyond my time limit. Log4Net and NLog have a small in-code footprint. EntLib is spammy, but I'd use a facade over it anyway. I accidentally mis-configured EntLib and it told me at run time. Log4Net didn't. I didn't have an accidental mis-config with NLog. EntLib comes with a nice looking app.config editor, which you 100% need. NLog has a config file schema so you get "intellisense". Log4Net comes with nada.

显然到目前为止我喜欢NLog。尽管有其他可用的解决方案，但还不足以使用它。
