1.工程里添加以下DLL：

2. config文件作以下配置（仅作参考，使用时根据.net实际环境修改后边的参数）


<?xml version="1.0"?>
<configuration>
  <configSections>  
    <sectionGroup name="common">
      <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
    </sectionGroup>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
  </configSections> 
  <common>
    <logging>
      <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net">
        <arg key="configType" value="INLINE" />
        <arg key="configFile" value="filename" />
      </factoryAdapter>
    </logging>
  </common>

  <log4net>
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <param name="File" value="d:/log/" />
      <param name="DatePattern" value=""Log_"yyyy-MM-dd".txt"" />
      <param name="appendToFile" value="true" />
      <param name="StaticLogFileName" value="false" />
      <param name="rollingStyle" value="Date" />
      <param name="MaxSizeRollBackups" value="1" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="conversionPattern" value="[%date] %newline%message%newline" />
      </layout>
    </appender>

    <appender name="RollingDebugLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <param name="File" value="d:/log/debug/" />
      <param name="DatePattern" value=""Log_"yyyy-MM-dd".txt"" />
      <param name="appendToFile" value="true" />
      <param name="StaticLogFileName" value="false" />
      <param name="rollingStyle" value="Date" />
      <param name="MaxSizeRollBackups" value="1" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="conversionPattern" value="[%date] %newline%message%newline" />
      </layout>
    </appender>
    
    
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%-5level %logger - %message%newline" />
      </layout>
    </appender>
    
    <root>
      <level value="DEBUG" />
      
      <appender-ref ref="ConsoleAppender"/>
  
      <appender-ref ref="ConsoleAppender" />
    </root>
    <logger name="FileLogger" additivity="false">
      <appender-ref ref="RollingLogFileAppender" />
      <level value="DEBUG" />
    </logger>

    
  <logger name="DebugLogger" additivity="false">
      <appender-ref ref="RollingDebugLogFileAppender" />
      <level value="INFO" />
    </logger>
  
    
    <logger name="ConsoleLogger" additivity="false">
      <appender-ref ref="ConsoleAppender" />
      <level value="DEBUG" />
    </logger>
  </log4net>
  
<startup><supportedRuntime version="v2.0.50727"/></startup>
</configuration>

3. 创建日志类

 public class LogUtil
    {
        private static ILog filelog = null;
        static LogUtil(){
            filelog = LogManager.GetLogger("FileLogger"); 
            if (filelog == null) {
                throw new Exception("没有名字为FileLogger的日志器");
            }
        }
        public static void  log(String typeName,String methoName,String message){
            String rs = "类：" + typeName + "\r\n方法：" + methoName + "\r\n异常信息：" + message; 
            filelog.Error(rs); 

        }
    }

4. 使用实例

 LogUtil.log("日志", "定时事件", "未查找到句柄，定时事件不执行");
