如何使用Log4Net(以编程方式,没有xml config)配置多个记录器?我需要它们写入不同的文件。
log4net仪表板上的该线程详细介绍了一种方法。
总结一下,希望不要剥离太多代码:
using log4net; using log4net.Appender; using log4net.Layout; using log4net.Repository.Hierarchy; // Set the level for a named logger public static void SetLevel(string loggerName, string levelName) { ILog log = LogManager.GetLogger(loggerName); Logger l = (Logger)log.Logger; l.Level = l.Hierarchy.LevelMap[levelName]; } // Add an appender to a logger public static void AddAppender(string loggerName, IAppender appender) { ILog log = LogManager.GetLogger(loggerName); Logger l = (Logger)log.Logger; l.AddAppender(appender); } // Create a new file appender public static IAppender CreateFileAppender(string name, string fileName) { FileAppender appender = new FileAppender(); appender.Name = name; appender.File = fileName; appender.AppendToFile = true; PatternLayout layout = new PatternLayout(); layout.ConversionPattern = "%d [%t] %-5p %c [%x] - %m%n"; layout.ActivateOptions(); appender.Layout = layout; appender.ActivateOptions(); return appender; } // In order to set the level for a logger and add an appender reference you // can then use the following calls: SetLevel("Log4net.MainForm", "ALL"); AddAppender("Log4net.MainForm", CreateFileAppender("appenderName", "fileName.log")); // repeat as desired
