C#通过log4net进行异常记录详解编程语言

C#通过log4net进行异常记录

C#中异常的记录也有一个模板，就是log4net。多的就不说了直接看怎么用的吧。 1、引用log4net.dll。

2、实现log4net的方法。

public class LogImplement 

 private ILog logger; 

 public LogImplement(ILog log) 

 this.logger = log; 

 public void Debug(object message) 

 this.logger.Debug(message); 

 public void Debug(object message, Exception e) 

 this.logger.Debug(message, e); 

 public void Warming(object message) 

 this.logger.Warn(message); 

 public void Warming(object message,Exception e) 

 this.logger.Warn(message, e); 

 public void Error(object message) 

 this.logger.Error(message); 

 public void Error(object message, Exception e) 

 this.logger.Error(message, e); 

 public void Info(object message) 

 this.logger.Info(message); 

 public void Info(object message, Exception e) 

 this.logger.Info(message, e); 

 public class LogFactory 

 static LogFactory() 

 FileInfo configFile = new FileInfo(AppDomain.CurrentDomain.BaseDirectory + @"Log.config"); 

 log4net.Config.XmlConfigurator.Configure(configFile); 

 public static LogImplement GetLogger(Type type) 

 return new LogImplement(LogManager.GetLogger(type)); 

 public static LogImplement GetLogger(string str) 

 return new LogImplement(LogManager.GetLogger(str)); 

3、配置文件

 configuration 

 configSections 

 section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net-net-2.0"/ 

 /configSections 

 log4net 

 root 

 appender-ref ref="ErrorLogFileAppender"/ 

 appender-ref ref="WarningFileAppender"/ 

 appender-ref ref="DebugLogFileAppender"/ 

 /root 

 !--记录warning-- 

 appender name="WarningFileAppender" type="log4net.Appender.RollingFileAppender" 

 file value="log/Warn.log"/ 

 appendToFile value="true"/ 

 maxSizeRollBackups value="10"/ 

 maximumFileSize value="1MB"/ 

 rollingStyle value="Size"/ 

 staticLogFileName value="true"/ 

 layout type="log4net.Layout.PatternLayout" 

 conversionPattern value="[%date] [%-5level] [%logger] - %message%newline"/ 

 /layout 

 filter type="log4net.Filter.LevelRangeFilter" 

 param name="LevelMin" value="WARN"/ 

 param name="LevelMax" value="WARN"/ 

 /filter 

 /appender 

 !--记录错误-- 

 appender name="ErrorLogFileAppender" type="log4net.Appender.RollingFileAppender" 

 file value="log/Error.log"/ 

 appendToFile value="true"/ 

 maxSizeRollBackups value="10"/ 

 maximumFileSize value="1MB"/ 

 rollingStyle value="Size"/ 

 staticLogFileName value="true"/ 

 layout type="log4net.Layout.PatternLayout" 

 conversionPattern value="[%date] [%-5level] [%logger] - %message%newline"/ 

 /layout 

 filter type="log4net.Filter.LevelRangeFilter" 

 param name="LevelMin" value="ERROR"/ 

 param name="LevelMax" value="ERROR"/ 

 /filter 

 /appender 

 !--记录调试日志-- 

 appender name="DebugLogFileAppender" type="log4net.Appender.RollingFileAppender" 

 file value="log/debug.log"/ 

 param name="AppendToFile" value="true"/ 

 param name="MaxSizeRollBackups" value="10"/ 

 param name="MaximumFileSize" value="1MB"/ 

 param name="StaticLogFileName" value="true"/ 

 param name="RollingStyle" value="Size"/ 

 layout type="log4net.Layout.PatternLayout" 

 param name="ConversionPattern" value="[%p] [%d{MM/dd/yyyy HH:mm:ss,fff}] [%t] [%c]- %m%n"/ 

 /layout 

 filter type="log4net.Filter.LevelRangeFilter" 

 param name="LevelMin" value="DEBUG"/ 

 param name="LevelMax" value="DEBUG"/ 

 /filter 

 /appender 

 !--调试模式，输出日志到控制台-- 

 appender name="ConsoleAppender" type="log4net.Appender.ColoredConsoleAppender" 

 mapping 

 level value="ERROR"/ 

 foreColor value="Red, HighIntensity"/ 

 !-- backColor value="Green" / -- 

 /mapping 

 mapping 

 level value="DEBUG"/ 

 foreColor value="Yellow, HighIntensity"/ 

 backColor value="Green"/ 

 /mapping 

 layout type="log4net.Layout.PatternLayout" 

 footer value="--------------------------------------------------------------------"/ 

 param name="ConversionPattern" value="[%p] [%d{MM/dd/yyyy HH:mm:ss,fff}] [%t] [%c]- %m%n"/ 

 /layout 

 filter type="log4net.Filter.LevelRangeFilter" 

 param name="LevelMin" value="DEBUG"/ 

 param name="LevelMax" value="ERROR"/ 

 /filter 

 /appender 

 /log4net 

 startup 

 supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/ 

 /startup 

 /configuration 

其中， 表示异常文件超过1M大小就自动新增文件；表示异常文件的路径；表示要支持的.net版本。至于其他属性在使用中自己可以慢慢体会。

4、记录异常

 

 public class RecordLog 

 public static void RecordException(Exception e) 

 LogImplement log = LogFactory.GetLogger(typeof(RecordLog)); 

 log.Error(e.Message + e.StackTrace); 

5、调用

 

 static void Main(string[] args) 

 try 

 string test = "123tr"; 

 int i = int.Parse(test);//制造一个异常 

 catch(Exception e) 

 RecordLog.RecordException(e);
