Log4Net使用入門

標籤：

1. 在NuGet程式包中添加log4net引用
2. 在config檔案裡面添加如下配置代碼 

    1 <configuration> 2   <configSections> 3     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> 4   </configSections> 5   <log4net> 6     <!--定義輸出到檔案中--> 7     <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> 8       <!--定義檔案存放位置--> 9       <file value="log\\"/>10       <appendToFile value="true"/>11       <rollingStyle value="Date"/>12       <datePattern value="yyyy\\yyyyMM\\yyyyMMdd‘.txt‘"/>13       <staticLogFileName value="false"/>14       <param name="MaxSizeRollBackups" value="100"/>15       <layout type="log4net.Layout.PatternLayout">16         <!--每條日誌末尾的文字說明-->17         <!--輸出格式-->18         <!--範例：2008-03-26 13:42:32,111 [10] INFO  Log4NetDemo.MainClass [(null)] - info-->19         <conversionPattern value="%newline %n記錄時間：%date %n線程ID:[%thread] %n記錄層級：  %-5level %n出錯類：%logger property: [%property{NDC}] - %n錯誤描述：%message%newline %n"/>20       </layout>21     </appender>22     <root>23       <level value="ERROR"/>24       <!--檔案形式記錄日誌-->25       <appender-ref ref="RollingLogFileAppender"/>26     </root>27   </log4net>28 </configuration>

3. 可以建立日誌共用類,以方便調用

    1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5  6 [assembly: log4net.Config.XmlConfigurator(Watch = true)] 7 namespace TestLog4Net 8 { 9    public  class LogHelper10     {11         /// <summary>12         /// 輸出日誌到Log4Net13         /// </summary>14         /// <param name="t"></param>15         /// <param name="ex"></param>16         #region static void WriteLog(Type t, Exception ex)17         public static void WriteLog(Type t, Exception ex)18         {19             log4net.ILog log = log4net.LogManager.GetLogger(t);20             log.Error("Error", ex);21         }22         #endregion23 24         /// <summary>25         /// 輸出日誌到Log4Net26         /// </summary>27         /// <param name="t"></param>28         /// <param name="msg"></param>29         #region static void WriteLog(Type t, string msg)30         public static void WriteLog(Type t, string msg)31         {32             log4net.ILog log = log4net.LogManager.GetLogger(t);33             log.Error(msg);34         }35         #endregion36     }37 }
