//Author:GaoBingBing

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

 

必备的组件：

              1.log4net.dll

              2.MySql.Data.dll

log4net.config:

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

    //错误级别:Info

    public static void Info(Exception ex, string message)

        return "自定义错误信息：" + message + "。系统错误信息:" + ex.Message + ",发生时间：" +

               DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");

    }

}

//Author:GaoBingBing

public class Log4NetConfig

{

    public static string DBServer = "ADONetAppender_DbServer";

    public static string File = "FileAppender";

}

就可以直接使用了!
