To add custom log information in Log4Net, you can achieve this by following these steps:<\/p>\n

    \n
  1. Create a custom log information class that can include fields such as timestamp, user ID, operation type, etc., which need to be recorded.<\/li>\n<\/ol>\n
    public<\/span> class<\/span> CustomLogInfo<\/span>\r\n{\r\n    public<\/span> DateTime Timestamp { get<\/span>; set<\/span>; }\r\n    public<\/span> string<\/span> UserId { get<\/span>; set<\/span>; }\r\n    public<\/span> string<\/span> Action { get<\/span>; set<\/span>; }\r\n}\r\n<\/code><\/pre>\n
      \n
    1. Define a custom layout pattern in the Log4Net configuration file to output custom log information to the log file.<\/li>\n<\/ol>\n
      <layout<\/span> type<\/span>=\"log4net.Layout.PatternLayout\"<\/span>><\/span>\r\n    <conversionPattern<\/span> value<\/span>=\"%date [%thread] %-5level %logger - %message %property{CustomInfo}%newline\"<\/span> \/><\/span>\r\n<\/layout<\/span>><\/span>\r\n<\/code><\/pre>\n
        \n
      1. Use the GlobalContext.Properties property of Log4Net in your code to store and retrieve custom log information.<\/li>\n<\/ol>\n
        GlobalContext.Properties[\"CustomInfo\"<\/span>] = customLogInfo.ToString();\r\nlog.Info(\"Log message with custom info\"<\/span>);\r\n<\/code><\/pre>\n
        By following the above steps, you can add custom log messages in Log4Net and have them output to the log file.<\/p>\n","protected":false},"excerpt":{"rendered":"
