注意以下要点在使用log4net时。

  1. Make sure to reference the correct version of the log4net assembly in your project.
  2. Configure log4net: Add a configuration section for log4net in the project’s configuration file (e.g. App.config or Web.config) to set up the logger’s output method, format, etc.
  3. Initiate log4net: To initialize log4net when the application starts, you can call the log4net.Config.XmlConfigurator.Configure() method in the code.
  4. Utilize a logger: When needing to keep track of logs, log the information by obtaining an instance of the logger (usually through the LogManager.GetLogger() method).
  5. Set the logging level: Adjust the level of logging as needed, such as debugging, information, warning, error, etc. This can be done by setting the element in the node of the configuration file, or by accessing the Logger.Level property in the code.
  6. Log output method: Choose the appropriate log output method based on the requirements, such as console, file, database, etc. Configure the output method through the element in the configuration file.
  7. Log format: Customize the format of the log according to your needs by setting the element in the configuration file.
  8. Exception handling: When catching an exception, you can use log4net to record the exception information for easier troubleshooting.
  9. Performance of logging: log4net offers several configuration options for performance optimization that can be adjusted as needed to enhance the performance of logging.
  10. Usage and maintenance of logs: In the process of project development, it is important to use logs effectively, record valuable information, and regularly maintain log files by deleting outdated entries to prevent them from becoming too large and affecting system performance.

In conclusion, when using log4net, it is important to pay attention to proper configuration, correct initialization, selecting suitable logging levels and output methods, and making necessary adjustments and maintenance as needed.
