Log4net is a framework component developed for recording system logs under. net. It is powerful and easy to use.
Usage:
1. Add a reference to log4net. dll in your project.
2. Set the configuration file app. config (you can also set a separate configuration file for log4net. Refer to carhui's log recording using log4net in. Net Program (example ))
Example:
When you repeatedly set the same appender in the root and logger fields, you will find that the same log information wi

are two solutions on the Internet: (1) create a class library to inherit from log4, load the configuration in the [Assembly] mode, and reference the class library in the web project; (2) dynamically load configurations in the Global File. I personally think that the methods provided by log4net are ready for use and there is no need to inherit them. We recommend using the (2) method.
2. Use of various appender

How do I enable log4net innteral debugging?
There are 2 different ways to enable internal debugging in log4net. These are listed below. The preferred metho
Over the past few days, I have been studying the socket program connected to. Net by Delphi, and finally made some progress.
Requirements:
The server intercepts the first four bytes and converts them to numbers. The second digit is the Business Code. It determines which business logic to call.
Using system; using system. collections. generic; using system. text; using system. io; using system. net. sockets; using system. threading; using pivasupdate; using log4net; using system. reflection; usi
Today, I made a one-day remote log configuration. Due to the lack of documents and strategies, debugging was very difficult. Most of the items searched on the Internet are only code-based and do not describe the principles at all. Finally, the configuration is successful, and now the process is organized as follows.
Summary: socket-based remote log is composed of the server and client. The server needs to start a Java class org.apache.log4j.net. socketserver, and the client uses socketappender.

Because this is a half-outsourcing project, the writing method is different from my previous habits, so I didn't see what went wrong.

When using the log component, you must also pay attention to the log level. Instead of outputting all levels of logs, there are too many log
There is a log4net User Guide in the garden, which is detailed. We recommend that you use log4net.
If you don't want to spend too much time on research, you can do it in five minutes by following the steps below:
1. Add a reference to log4net. dll
2. modify the configuration file. Take app. config as an example. The reference content is as follows:

3.CodeRead ConfigurationThis step is very simple. You can read the log4net configuration in the assemblyinfo. 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)]
