运行VS新建 c# Windows应用程序
添加引用LogNET
新建一个应用程序配置文件nfig（具体内容附在后面）
打开Formcs
在Namespace上添加一行 [assembly: lognetConfigDOMConfigurator(Watch=true)]
（或者 编辑Assemblycs文件添加如下内容:
[assembly:lognetConfigDOMConfigurator( ConfigFileExtension=configWatch=true)] ）
在类Form中添加一个静态变量
private static readonly lognetILog log = lognetLogManagerGetLogger(SystemReflectionMethodBaseGetCurrentMethod()DeclaringType);
添加一个按钮在按钮处理函数中添加一行 logWarn(你好！);
运行程序点一下按钮
