, respectively defined as A.B.C and a.b, then we say A.B is the ancestor of A.B.C. Each logger inherits the ancestor's attributes.The log4net framework defines a ilog interface, and all logger classes must implement this interface. If you want to implement a custom logger, you must first implement this interface. You can refer to a few examples under the/extension directory.The Ilog interface is defined as follows:　　Public interface ILog { void Debug (Object message); void Info (Object message

The common problem is not very useful. The reason is that it is too complicated. However, this item appears more and more frequently, so you have to write something for later use. This article only gives a brief description of the use of log4net. All aspects related to expansion and development are ignored. To use log4net, you must be familiar with logger, appender, and layout. Logger is a logger. We use related methods to record logs. appender is used to set the storage mode and location of lo

Error: error message. It is also widely used. Fatal: The level is relatively high. Major errors. You can stop the program directly at this level. Shouldn't it be an error! Don't be so nervous, it's actually a level of problem. 　5. Log call: Write a class at Will here, and the call is so simple. The core of

Logger names can be arbitrary strings, but they should generally be based on the package name or class name of the component being logged, such as java.net or javax.swing. In addition, you can create an "anonymous" Logger whose name is not stored in the Logger namespace. you can obtain a Logger object by calling a GetLogger factory method. These methods either create a new Logger, or return an appro

Log Management-Log4net, log-log4net Introduction The log4net library is implemented by the Apache log4j framework on the Micorsoft. NET platform. It is a tool that helps programmers to output log information to various targets (such as the console, files, and databases. (Baidu encyclopedia) In actual projects, log4net is a very convenient tool for programmers to record the log information during system operation, especially for bs systems. This article briefly explains how to use it. It is the m

CS file of the application assembly.For winform applications, you can add[Assembly: log4net. config. domconfigurator ()] or[Assembly: log4net. config. xmlconfigurator ()]For webform, you can add[Assembly: log4net. config. domconfigurator (configfile = "Web. config", watch = true)] Note: If you are using a nunit test friend, us
