asp.net Log4Net错误日志个人总结

1)创建Global.asax

protected void Application_Start(object sender, EventArgs e)
{

log4net.Config.XmlConfigurator.Configure();

}

protected void Application_Error(object sender, EventArgs e)
{
Exception ex = Server.GetLastError().GetBaseException();
log4net.ILog log = log4net.LogManager.GetLogger("LogServer");
log.Error(ex);

}

2)web.config中进行配置

a)将<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>放到<configSections>中。

<configSections>
<!--错误日志配置-->
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>

</configSections>

b)将<log4net>..................</log4net>放到</system.web>之后， <system.codedom>之前。

<!--错误日志配置-->
<log4net>
<appender name="TraceAppender" type="log4net.Appender.TraceAppender">
