Log4Net详细配置
关于Log4Net配置主要分几步
第一步：下载log4net.dll（log4net官网：http://logging.apache.org/log4net/download_log4net.cgi）
第二步：在项目中添加对log4net.dll的引用
第三步：配置log4net

</log4net>
第四步：在程序运行之前，加载log4net的配置
log4net.Config.XmlConfigurator.Configure("log4net配置文件的路径");
第五步：使用log4net记录日志
ILog logger = log4net.LogManager.GetLogger("SystemLogger");
log4net.Info("info");
log4net.Error("error");
.....
