log4net的简单使用
最近记录log时用了一下log4net,下面简单介绍下log4net的用法。
1、下载引用log4net组件
2、配置
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date - %message%newline" />
</layout>
</appender>
<appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="log\ErrorLog\\" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="100" />
<param name="MaxFileSize" value="1024000" />
<param name="StaticLogFileName" value="false" />
<param name="DatePattern" value="yyyy-MM-dd".log"" />
<param name="RollingStyle" value="Date" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="[%d] %m%n" />
</layout>
</appender>
<appender name="InfoAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="log\InfoLog\\" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="100" />
<param name="MaxFileSize" value="1024000" />
<param name="StaticLogFileName" value="false" />
<param name="DatePattern" value="yyyy-MM-dd".log"" />
<param name="RollingStyle" value="Date" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="[%d] %m%n" />
</layout>
</appender>
<logger name="logerror">
<level value="ERROR" />
<appender-ref ref="ErrorAppender" />
<appender-ref ref="ConsoleAppender" />
</logger>
<logger name="loginfo">
<level value="INFO" />
<appender-ref ref="InfoAppender" />
<appender-ref ref="ConsoleAppender" />
</logger>
</log4net>
</configuration>
3、工具类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using log4net;
namespace Wind.Cloud.Lua
{
public class LogHelper
{
private LogHelper()
{
}
private static readonly ILog loginfo = log4net.LogManager.GetLogger("loginfo");
private static readonly ILog logerror = log4net.LogManager.GetLogger("logerror");
public static void StartLog()
{
//读取配置
log4net.Config.XmlConfigurator.Configure();
}
#region 写信息日志
/// <summary>
/// 写信息日志
/// </summary>
/// <param name="info"></param>
public static void WriteInfoLog(string info)
{
if (loginfo.IsInfoEnabled)
{
loginfo.Info(info);
}
}
#endregion
#region 写错误日志
/// <summary>
/// 写错误日志
/// </summary>
/// <param name="info"></param>
public static void WriteErrorLog(string info)
{
if (logerror.IsErrorEnabled)
{
logerror.Error(info);
}
}
#endregion
}
}
4、使用
LogHelper.StartLog();
string info = "test";
LogHelper.WriteInfoLog(info);
