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); 
            } 
        }
