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);
            }
        }
    }
}
