摘要：
1.为Logs创建一个新的Class类；代码如下：1publicclassApiLogs2｛3publicstaticintLog_Level｛get；set；｝4privatestaticbolinitialized=false；5私有静态创建ILoglog=日志管理器。GetLogger（“ApiLogs”）；6staticApiLogs（）7｛8if（！in
1、新建Logs的Class类；代码如下：
1 public class ApiLogs 2 { 3 public static int Log_Level { get; set; } 4 private static bool initialized = false; 5 private static readonly ILog log = LogManager.GetLogger("ApiLogs"); 6 static ApiLogs() 7 { 8 if (!initialized) 9 { 10 Initialize(); 11 initialized = true; 12 } 13 } 14 private static void Initialize() 15 { 16 17 FileInfo fi = new FileInfo(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile); 18 if (fi.Exists) 19 { 20 XmlConfigurator.ConfigureAndWatch(fi); 21 } 22 if (!LogManager.GetRepository().Configured) 23 { 24 string filePath = (Path.Combine(Path.GetDirectoryName(new Uri(Assembly.GetCallingAssembly().GetName().CodeBase).LocalPath), "Carpa.config")); 25 fi = new FileInfo(filePath); 26 if (fi.Exists) 27 { 28 XmlConfigurator.ConfigureAndWatch(fi); 29 } 30 else 31 { 32 Trace.TraceWarning("配置文件 {0} 不存在", fi.FullName); 33 } 34 } 35 } 36 37 38 /// <summary> 39 /// 调试输出 40 /// </summary> 41 /// <param name="message"></param> 42 public static void Debug(object message) 43 { 44 if (Log_Level >= 4) 45 { 46 log.Debug(message);

2、定义Log4net.config配制文件
<?xml version="1.0" encoding="gb2312" ?> <configuration> <configSections> <section name="log4net" type="System.Configuration.IgnoreSectionHandler" /> </configSections> <log4net> <appender name="DebugInfoAppender" type="log4net.Appender.RollingFileAppender"> <file type="log4net.Util.PatternString" value="dataCarpaLog_Info.txt" /> <appendToFile value="true" /> <maximumFileSize value="1024KB"/> <maxSizeRollBackups value="7"/> <CountDirection value="1"/> <RollingStyle value="Size"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%newline%date [%thread] %-5level - %message%newline" /> </layout> <filter type="log4net.Filter.LevelRangeFilter"> <levelMin value="DEBUG" /> <levelMax value="INFO" /> </filter> </appender> <appender name="WarnErrorFatalAppender" type="log4net.Appender.RollingFileAppender"> <file type="log4net.Util.PatternString" value="dataCarpaLog_Error.txt" /> <appendToFile value="true" /> <RollingStyle value="Date" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%newline%date [%thread] %-5level - %message%newline" /> </layout> <filter type="log4net.Filter.LevelRangeFilter"> <levelMin value="WARN" /> <levelMax value="FATAL" /> </filter> </appender> <appender name="DebugAppender" type="Carpa.Logging.Appender.DebugAppender"> <layout type="Carpa.Logging.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %type - %message%newline" /> </layout> </appender> <appender name="ApiInfoAppender" type="log4net.Appender.RollingFileAppender"> <file type="log4net.Util.PatternString" value="dataApiLog.txt" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/> <appendToFile value="true" /> <maximumFileSize value="5MB"/> <maxSizeRollBackups value="7"/> <CountDirection value="1"/> <RollingStyle value="Size"/> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%newline%date [%thread] %-5level - %message%newline" /> </layout> <!--<filter type="log4net.Filter.LoggerMatchFilter"> <loggerToMatch value="ApiLogs" /> </filter> <filter type="log4net.Filter.DenyAllFilter" />--> </appender> <logger name="ApiLogs"> <level value="ALL" /> <appender-ref ref="ApiInfoAppender" /> </logger> <logger name="test.Logging.Log"> <level value="INFO" /> <appender-ref ref="FileAppender" /> <appender-ref ref="DebugInfoAppender" /> <appender-ref ref="WarnErrorFatalAppender" /> </logger> </log4net> </configuration>
核心说明：通过该类logManager.GetLogger("Name")的Name参数来区分，并定义配制文件中logger中name与Getlogger的Name名称一致
