在.Net程序中使用log4net记录日志(示例)
log4j是java开发人员所熟悉，他提供了强大的日志记录功能，log4net是为.Net记录日志开发的.使用示例如下(C#)：
1、app.config文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="log4net-config-file" value="log4net.config"/>
</appSettings>
</configuration>
2、log4net.config文件
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<!-- This section contains the log4net configuration settings -->
<log4net>
<!-- Define some output appenders -->
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="Log\\LQSS-SS-log.txt" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="10" />
<param name="MaximumFileSize" value="100KB" />
<param name="RollingStyle" value="Size" />
<param name="StaticLogFileName" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="Header" value="[Header]\r\n" />
<param name="Footer" value="[Footer]\r\n" />
<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n" />
</layout>
</appender>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] <%X{auth}> - %m%n" />
</layout>
</appender>
<!-- Setup the root category, add the appenders and set the default level -->
<root>
<level value="INFO" />
<appender-ref ref="RollingLogFileAppender" />
</root>
<root>
<level value="DEBUG" />
<appender-ref ref="ConsoleAppender" />
</root>
</log4net>
</configuration>
3、代码文件
using log4net;
using log4net.Config;
class Program
{
private static ILog logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
try
{
DOMConfigurator.Configure(
new FileInfo(ConfigurationSettings.AppSettings["log4net-config-file"]));
logger.Info("Start application...");
Console.Writeline(“请按 <enter> 键退出...");
System.Console.ReadLine();
}
catch (Exception e)
{
logger.Info (e);
}
}
}
