What's the most widely-used logging framework in C#?
提问by Nosrama
I'm looking into how to implement logging in my C# app - its a DLL class library. What logging frameworks are most widely used - what would give users of my DLL the most flexibility and configurability? Is there a C# equivalent of log4j?
我正在研究如何在我的 C# 应用程序中实现日志记录 - 它是一个 DLL 类库。哪些日志框架使用最广泛 - 什么会给我的 DLL 用户最大的灵活性和可配置性？是否有等效于 log4j 的 C#？

People have been using Enterprise Libraryextensively. But it may be true that developers are switching to other products these days.
人们一直在广泛使用企业库。但是，如今开发人员正在转向其他产品，这可能是真的。
I'd check it out and see if it has the necessary functionality you need and not too much bloat.
我会检查一下，看看它是否具有您需要的必要功能，并且没有太多膨胀。

Enterprise Library.It's robust and comes straight from Microsoft with all their best practices included. We use it in all our projects. It's very flexible and there is a UI tool that you can use in case you don't want to mess around with managing logging from the config file.
企业图书馆。它很健壮，直接来自 Microsoft，包括他们的所有最佳实践。我们在所有项目中都使用它。它非常灵活，并且有一个 UI 工具可供您使用，以防您不想从配置文件管理日志记录。

log4net is almost certainly the most common.
log4net 几乎可以肯定是最常见的。
But I use Common.Logging - http://netcommon.sourceforge.net/as it gives me flexibility
但我使用 Common.Logging - http://netcommon.sourceforge.net/因为它给了我灵活性
There are a variety of logging implementations for .NET currently in use, log4net, Enterprise Library Logging, NLog, to name the most popular. The downside of having differerent implementation is that they do not share a common interface and therefore impose a particular logging implementation on the users of your library.
Common.Logging library introduces a simple abstraction to allow you to select a specific logging implementation at runtime. Thus you can defer the decision what particular logging library to use until deployment. Adapters are used for plugging a particular logging system into Common.Logging.
当前使用的 .NET 有多种日志记录实现，log4net、企业库日志记录、NLog 等最流行。具有不同实现的缺点是它们不共享公共接口，因此对库的用户强加了特定的日志记录实现。
Common.Logging 库引入了一个简单的抽象，允许您在运行时选择特定的日志记录实现。因此，您可以推迟决定使用哪个特定的日志库，直到部署。适配器用于将特定的日志系统插入 Common.Logging。
