使用 Log4Net 做日志

引入 Log4net 包

编写 LogHelper 类

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 
 6 [assembly: log4net.Config.XmlConfigurator(Watch = true)]//一定要写
 7 namespace TestLog4Net
 8 {
 9    public  class LogHelper
10     {
11         /// <summary>
12         /// 输出日志到Log4Net
13         /// </summary>
14         /// <param name="t"></param>
15         /// <param name="ex"></param>
16         #region static void WriteLog(Type t, Exception ex)
17 
18         public static void WriteLog(Type t, Exception ex)
19         {
20             log4net.ILog log = log4net.LogManager.GetLogger(t);
21             log.Error("Error", ex);
22         }
23 
24         #endregion
25 
26         /// <summary>
27         /// 输出日志到Log4Net
28         /// </summary>
29         /// <param name="t"></param>
30         /// <param name="msg"></param>
31         #region static void WriteLog(Type t, string msg)
32 
33         public static void WriteLog(Type t, string msg)
34         {
35             log4net.ILog log = log4net.LogManager.GetLogger(t);
36             log.Error(msg);
37         }
38 
39         #endregion
40 
41 
42     }
43 }

在启动项目的配置文件里添加配置

 1 <?xml version="1.0"?>
 2 <configuration>
 3   <configSections>
 4     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
 5   </configSections>
 6   <log4net>
 7     <!--定义输出到文件中-->
 8     <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
 9       <!--定义文件存放位置-->
10       <file value="log\\"/>
11       <appendToFile value="true"/>
12       <rollingStyle value="Date"/>
13       <datePattern value="yyyy\\yyyyMM\\yyyyMMdd'.txt'"/>
14       <staticLogFileName value="false"/>
15       <param name="MaxSizeRollBackups" value="100"/>
16       <layout type="log4net.Layout.PatternLayout">
17         <!--每条日志末尾的文字说明-->
18         <!--输出格式-->
19         <!--样例：2008-03-26 13:42:32,111 [10] INFO  Log4NetDemo.MainClass [(null)] - info-->
20         <conversionPattern value="%newline %n记录时间：%date %n线程ID:[%thread] %n日志级别：  %-5level %n出错类：%logger property: [%property{NDC}] - %n错误描述：%message%newline %n"/>
21       </layout>
22     </appender>
23     <root>
24       <level value="ERROR"/>
25       <!--文件形式记录日志-->
26       <appender-ref ref="RollingLogFileAppender"/>
27     </root>
28   </log4net>
29 </configuration>

引用时直接在事件处填写

 LogHelper.WriteLog(typeof(FormMain), "测试Log4Net日志是否写入");


即可
