C#通过log4net进行异常记录

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="logWarn.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="logError.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="logdebug.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);
            }
        }
