	 }
	 }
	 }
	 catch (Exception ex)
	 {
	 WriteLog( "创建错误", ex );
	 }
	 }
	 }
	 //用的方法如下：
	 LogerHelper.LogToFile( "创建日志");
	 //这个将生成诸如这样的Error/年/月/日/文件名.log的日志LogerHelper.WriteLog("单独的日志");
	 //这个将写入到Error/log.log文件夹下，只记录一个单独的infoLogerHelper.WriteLog("单独的日志",ex);
	 //这个也将写入到Error/log.log文件夹下，记录单独的info，和一个异常信息//注意：此方法在winform里边是不用配置log4net的节点的，可以将附件中的log4net
试试其它关键字
同语言下
可能有用的
