Log4Net簡單使用

標籤：errorlog   eve   log   使用   param   stat   ado   set   sse   

     1.設定檔添加

<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>

<log4net>
<!--<logger name="logerror">
<level value="ERROR" />
<appender-ref ref="ErrorAppender" />
</logger>-->
<logger name="loginfo">
<level value="INFO" />
<appender-ref ref="InfoAppender" />
</logger>
<!--<appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="Log\\LogError\\" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="100" />
<param name="MaxFileSize" value="10240" />
<param name="StaticLogFileName" value="false" />
<param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
<param name="RollingStyle" value="Date" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%n異常時間：%d %n異常層級：%-5p%n異常內容：%m%n" />
</layout>
--><!--&lt; &gt; = <> %n = 斷行符號--><!--
</appender>-->
<appender name="InfoAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="LogInfo\\" />
<param name="AppendToFile" value="true" />
<param name="MaxFileSize" value="10240" />
<param name="MaxSizeRollBackups" value="100" />
<param name="StaticLogFileName" value="false" />
<param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
<param name="RollingStyle" value="Date" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="日誌時間：%d %n記錄層級：%-5p %n日誌內容：%m%n%n" />
</layout>
</appender>
</log4net>

2.添加Log4Net引用檔案

3.配置[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]在 AssemblyInfo 下

4.調用方法寫日誌

 1 public class LogHelper 2 { 3 public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo"); 4  5 public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror"); 6  7 //public static void SetConfig() 8 //{ 9 // log4net.Config.XmlConfigurator.Configure();10 //}11 12 //public static void SetConfig(FileInfo configFile)13 //{14 // log4net.Config.XmlConfigurator.Configure(configFile);15 //}16 17 public static void WriteLog(string info)18 {19 if (loginfo.IsInfoEnabled)20 {21 loginfo.Info(info);22 }23 }24 25 public static void WriteErrorLog(string info)26 {27 if (logerror.IsErrorEnabled)28 {29 logerror.Error(info);30 }31 }32 }
