step1
引用log4net.dll
step2
指定log4net配置文件
添加
[assembly:log4net.Config.XmlConfigurator(Watch=true)]
step3
在步骤2中指定的配置文件添加log4net配置.
在示例配置中添加了控制台,文件以及数据库(以mysql为例示范)日志,可按需要配置.
<?xmlversion="1.0" encoding="utf-8" ?>

</configuration>
step4
在需要使用日志的类添加如下成员
// Create alogger for use in this class
private static readonly ILog log =LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// NOTE that usingSystem.Reflection.MethodBase.GetCurrentMethod().DeclaringType
// is equivalent totypeof(LoggingExample) but is more portable
// i.e. you can copy the code directlyinto another class without
// needing to edit the code.
然后调用log.Info("Hello,world!")即可.
效果

注意：
获取当前methodname,可通过new StackFrame().GetMethod().Name,相当于new StackTrace().GetFrame(0).GetMethod().Name，获取调用堆栈上一个方法,可通过newStackTrace().GetFrame(1).GetMethod().Name.
