log4net 使用demo mvc
Global.asax加入这句，log4net入口
- 配置写在web.config中，Global.asax加入这句
log4net.Config.XmlConfigurator.Configure();
- 配置在运行目录的log4net.config中，Global.asax加入这句
var logCfg = new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config");log4net.Config.XmlConfigurator.ConfigureAndWatch(logCfg);
代码
1 //Type type = MethodBase.GetCurrentMethod().DeclaringType;
2 ILog logWriter = LogManager.GetLogger("Demo");//(type);
3 logWriter.Error(exceptionStr); //将这个文本写入log，根据配置文件，这里写入文本
