log4net 测试实例

log4net配置可以分为以下几个部分：

1、配置App.config文件，在<configuration>节点下加入

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

另外在<configuration>节点下还要加入一个节点

< log4net  debug ="false" >
     < appender  name ="LogFileAppender"  type ="log4net.Appender.FileAppender"   >
         < param  name ="File"  value ="Log\Log.txt"   />
         < param  name ="AppendToFile"  value ="true"   />
         < layout  type ="log4net.Layout.PatternLayout" >
             < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c [%x] - %m%n"   />
         </ layout >
     </ appender >
     < appender  name ="HttpTraceAppender"  type ="log4net.Appender.ASPNetTraceAppender"   >
         < layout  type ="log4net.Layout.PatternLayout" >
             < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c [%x] - %m%n"   />
         </ layout >
     </ appender >
     < appender  name ="EventLogAppender"  type ="log4net.Appender.EventLogAppender"   >
         < layout  type ="log4net.Layout.PatternLayout" >
             < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c [%x] - %m%n"   />
         </ layout >
     </ appender >
     < appender  name ="RollingLogFileAppender"  type ="log4net.Appender.RollingFileAppender" >
         < param  name ="File"  value ="Log\Log.txt"   />
         < param  name ="AppendToFile"  value ="true"   />
         < param  name ="MaxSizeRollBackups"  value ="10"   />
         < param  name ="MaximumFileSize"  value ="5MB"   />
         < param  name ="RollingStyle"  value ="Size"   />
         < param  name ="StaticLogFileName"  value ="true"   />
         < layout  type ="log4net.Layout.PatternLayout" >
             < param  name ="ConversionPattern"  value ="%d [%t] %-5p %c [%x] - %m%n"   />
         </ layout >
     </ appender >
     < root >
         < level  value ="DEBUG"   />
         < appender-ref  ref ="LogFileAppender"   />
     </ root >
</ log4net >

2、将log4net.dll 文件引用到工程中，并在AssemblyInfo.cs文件中加入配置项
[assembly: log4net.Config.XmlConfiguratorAttribute(Watch=true)]

3、应用log4net，在操作类中使用log4net

using  System;
using  System.Configuration;
using  System.IO;
using  log4net;
using  log4net.Config;

namespace  Log4NetTest
{
    /**//// <summary>
    /// Summary description for Class1.
    /// </summary>
    class MainTest
    {
        private static ILog logger = LogManager.GetLogger(typeof(MainTest));
        /**//// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {
            try
            {
                logger.Info("Start application");
                logger.Debug("Debug Ilog");
                int a = 0;
                int b = 10 / a;
            }
            catch (Exception e) 
            {
                logger.Info (e.StackTrace, e);
            }
        }
    }
}
