在C#中使用LOG4NET（winform程序）

下載lognet （Google lognet）  
 
unzip lognet  
 
運行VS新建 c# Windows應用程序  
 
添加引用LogNET  
 
新建一個應用程序配置文件nfig（具體內容附在後面）  
 
打開Formcs  
 
  在Namespace上添加一行  [assembly: lognetConfigDOMConfigurator(Watch=true)]  
（或者 編輯Assemblycs文件添加如下內容:  
[assembly:lognetConfigDOMConfigurator( ConfigFileExtension=configWatch=true)] ） 
 
  在類Form中添加一個靜態變量  
 
                private static readonly lognetILog log = lognetLogManagerGetLogger(SystemReflectionMethodBaseGetCurrentMethod()DeclaringType);  
 
 
 
添加一個按鈕在按鈕處理函數中添加一行 logWarn(你好！);  
 
 
 
運行程序點一下按鈕  
 
 
 
OK打開Bin\Debug\logfiletxt可以看到你好
