配置log4net以写入不同的日志文件，没有配置文件

我想做这个：

配置Log4net以写入多个文件

但我想使用代码配置。 我该怎么做呢？

这是我尝试过的：

// Configure log A Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository(); PatternLayout patternLayout = new PatternLayout(); patternLayout.ConversionPattern = "%date %level %logger: %message%newline"; patternLayout.ActivateOptions(); RollingFileAppender appender = new RollingFileAppender(); appender.Name = @"MyLogA"; appender.File = @"C:\Temp\MyLogs\A.log"; appender.AppendToFile = true; appender.MaxSizeRollBackups = 2; appender.RollingStyle = RollingFileAppender.RollingMode.Size; appender.MaximumFileSize = "10MB"; appender.Layout = patternLayout; appender.LockingModel = new FileAppender.MinimalLock(); appender.StaticLogFileName = true; appender.ActivateOptions(); hierarchy.Root.AddAppender(appender); hierarchy.Configured = true; // Configure log B Hierarchy hierarchyB = (Hierarchy)LogManager.GetRepository(); PatternLayout patternLayoutB = new PatternLayout(); patternLayoutB.ConversionPattern = "%date %level %logger: %message%newline"; patternLayoutB.ActivateOptions(); RollingFileAppender appenderB = new RollingFileAppender(); appenderB.Name = @"MyLogB"; appenderB.File = @"C:\Temp\MyLogs\B.log"; appenderB.AppendToFile = true; appenderB.MaxSizeRollBackups = 2; appenderB.RollingStyle = RollingFileAppender.RollingMode.Size; appenderB.MaximumFileSize = "10MB"; appenderB.Layout = patternLayout; appenderB.LockingModel = new FileAppender.MinimalLock(); appenderB.StaticLogFileName = true; appenderB.ActivateOptions(); hierarchyB.Root.AddAppender(appenderB); hierarchyB.Configured = true; // Test Log A var loggerA = log4net.LogManager.GetLogger("MyLogA"); loggerA.Info("TestA"); loggerA.Info("TestA"); loggerA.Info("TestA"); loggerA.Info("TestA"); loggerA.Info("TestA"); // Test Log B var loggerB = log4net.LogManager.GetLogger("MyLogB"); loggerB.Info("TestB"); loggerB.Info("TestB"); loggerB.Info("TestB"); loggerB.Info("TestB"); loggerB.Info("TestB"); 

但是当我这样做时，所有十条日志消息都被转储到LogA和LogB中，它们不会转到各自的日志文件。

我怎样才能让它发挥作用？

我不完全理解为什么，但以下修复了这个问题：

 var hierarchy = (Hierarchy)LogManager.GetRepository(); hierarchy.Threshold = Level.Debug; // Configure LoggerA string logNameA = @"A"; string fileNameA = @"C:\Temp\MyLogs\A.log"; var loggerA = hierarchy.LoggerFactory.CreateLogger("LoggerA"); loggerA.Hierarchy = hierarchy; loggerA.AddAppender(CreateFileAppender(logNameA,fileNameA)); loggerA.Repository.Configured = true; loggerA.Level = Level.Debug; ILog logA = new LogImpl(loggerA); // Configure LoggerB string logNameB = @"B"; string fileNameB = @"C:\Temp\MyLogs\B.log"; var loggerB = hierarchy.LoggerFactory.CreateLogger("LoggerB"); loggerB.Hierarchy = hierarchy; loggerB.AddAppender(CreateFileAppender(logNameB, fileNameB)); loggerB.Repository.Configured = true; loggerB.Level = Level.Debug; ILog logB = new LogImpl(loggerB); // Test logA.Error("logA"); logA.Error("logA"); logA.Error("logA"); logA.Error("logA"); logA.Error("logA"); logB.Error("logB"); logB.Error("logB"); logB.Error("logB"); logB.Error("logB"); logB.Error("logB"); logB.Error("logB"); 

CreateFileAppender()是：

 private static IAppender CreateFileAppender(string name, string fileName) { PatternLayout patternLayout = new PatternLayout(); patternLayout.ConversionPattern = "%date %level %logger: %message%newline"; patternLayout.ActivateOptions(); RollingFileAppender appender = new RollingFileAppender(); appender.Name = name; appender.File = fileName; appender.AppendToFile = true; appender.MaxSizeRollBackups = 2; appender.RollingStyle = RollingFileAppender.RollingMode.Size; appender.MaximumFileSize = "10MB"; appender.Layout = patternLayout; appender.LockingModel = new FileAppender.MinimalLock(); appender.StaticLogFileName = true; appender.ActivateOptions(); return appender; }
