Log4net 1.2.10.0 的配置使用

本文转自：http://blog.csdn.net/nileel/archive/2008/03/26/2220306.aspx

 

项目中添加引用log4net.dll，目前最新版是1.2.10.0。
 
初始化时执行一次Configure。
log4net.Config.XmlConfigurator.Configure(new FileInfo("logconfig.xml"));
 
在需要使用的类中声明log。使用 typeof(类名) 做参数。
private log4net.ILog log = log4net.LogManager.GetLogger(typeof(SomeClass));
 
使用：

if(log.IsDebugEnabled)
log.Debug("some message");
//...
try{...}
catch(Exception ex)
{
log.Error("some error", ex);
}

 
================================
logconfig.xml的内容如下：(主体是官方示例中的配置，居然有拼写和格式错误)
