在这里，记录我在项目中使用log4net记录本地日志的步骤。在不会之前感觉很难，很神秘，一旦会了之后其实没那么难。其实所有的事情都是一样的，下面我就分享一下我使用log4Net的经验。

第一步：首先从Visual Studio中的Nuget包管理中搜索下载 Log4Net dll文件如下图：

选择安装的项目(哪个类库中需要记录日志就勾选上)

第二步：打开配置文件 WinFrom就是 App.config Web就是 web.config 将以下配置信息加入

<configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /></configSections><log4net> <logger name="SysRFLogger"> <level value="DEBUG" /> <appender-ref ref="SysRFAppender" /> </logger> <logger name="DebugRFLogger"> <level value="DEBUG" /> <appender-ref ref="DebugAppender" /> </logger> <logger name="MsgLogger"> <level value="DEBUG" /> <appender-ref ref="MsgAppender" /> </logger> <logger name="OperInfoLogger"> <level value="DEBUG" /> <appender-ref ref="OperInfoAppender" /> </logger> <appender name="SysRFAppender" type="log4net.Appender.RollingFileAppender"> <file value="Logs/syslog.log" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <preserveLogFileNameExtension value="true" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout">  <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> </appender> <appender name="DebugAppender" type="log4net.Appender.RollingFileAppender"> <file value="Logs/sysDebuglog.log" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <preserveLogFileNameExtension value="true" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout">  <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> </appender> <appender name="MsgAppender" type="log4net.Appender.RollingFileAppender"> <file value="Logs/Messagelog.log" /> <appendToFile value="true" /> <rollingStyle value="Date" /> <preserveLogFileNameExtension value="true" /> <datePattern value="yyyyMMdd" /> <layout type="log4net.Layout.PatternLayout">  <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" /> </layout> </appender> <appender name="OperInfoAppender" type="log4net.Appender.AdoNetAppender"> <bufferSize value="1" /> <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=4.0.30319.18020, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> <commandText value="INSERT INTO LOG_USEROPERLOG ([ID],[Date],[User],[Flag],[OperInfo],[OperFlag],[OperResult],[Message]) VALUES (@Id,@log_date, @user, @flag, @operinfo,@operflag, @operresult, @message)" /> <parameter>  <parameterName value="@Id" />  <dbType value="String" />  <size value="36" />  <layout type="NT.MultithreadingTaskService.Log.Layout.UserOperLayOut,NT.MultithreadingTaskService.Log">  <param name="ConversionPattern" value="%property{ID}" />  </layout> </parameter> <parameter>  <parameterName value="@log_date" />  <dbType value="DateTime" />  <layout type="log4net.Layout.RawTimeStampLayout" /> </parameter> <parameter>  <parameterName value="@user" />  <dbType value="String" />  <size value="64" />  <layout type="NT.MultithreadingTaskService.Log.Layout.UserOperLayOut,NT.MultithreadingTaskService.Log">  <param name="ConversionPattern" value="%property{User}" />  </layout> </parameter> <parameter>  <parameterName value="@flag" />  <dbType value="Int32" />  <layout type="NT.MultithreadingTaskService.Log.Layout.UserOperLayOut,NT.MultithreadingTaskService.Log">  <param name="ConversionPattern" value="%property{Flag}" />  </layout> </parameter> <parameter>  <parameterName value="@operinfo" />  <dbType value="String" />  <size value="255" />  <layout type="NT.MultithreadingTaskService.Log.Layout.UserOperLayOut,NT.MultithreadingTaskService.Log">  <param name="ConversionPattern" value="%property{OperInfo}" />  </layout> </parameter> <parameter>  <parameterName value="@operflag" />  <dbType value="String" />  <size value="32" />  <layout type="NT.MultithreadingTaskService.Log.Layout.UserOperLayOut,NT.MultithreadingTaskService.Log">  <param name="ConversionPattern" value="%property{OperFlag}" />  </layout> </parameter> <parameter>  <parameterName value="@operresult" />  <dbType value="String" />  <size value="255" />  <layout type="NT.MultithreadingTaskService.Log.Layout.UserOperLayOut,NT.MultithreadingTaskService.Log">  <param name="ConversionPattern" value="%property{OperResult}" />  </layout> </parameter> <parameter>  <parameterName value="@message" />  <dbType value="String" />  <size value="4000" />  <layout type="NT.MultithreadingTaskService.Log.Layout.UserOperLayOut,NT.MultithreadingTaskService.Log">  <param name="ConversionPattern" value="%property{Message}" />  </layout> </parameter> </appender> <root> <level value="DEBUG" /> <appender-ref ref="SysRFAppender" /> </root></log4net>

以上节点具体参数这里不做解释，可以上网查询帮助文档

注意：这两段XML要放在configuration 节点下靠前
