Log4net 封装用法

在这之前也使用过log4net，但使用起来总感觉不是很舒服，一不留神配置就写错了，配置一个新的日志花很多时间调试，win版和web版还有一些区别，经过公司大神（凯哥）帮助，直接使用封装好的类，简单粗暴，美！

上代码，一切都安静了。。。。

using System.Xml;

    public class Log4netHelper
    {       
        static Log4netHelper()
        {
            Init();
        }
        public static void Init()
        {
            string path = AppDomain.CurrentDomain.BaseDirectory + @"log4netConfig.xml";
            XmlDocument xmlDoc = new XmlDocument();

            if (System.IO.File.Exists(path))

            if (log.IsInfoEnabled) log.Info(message);
        }
        
    }
}

2017.12.5 修改

原来封装在一个类的方法有个小问题,不能得到正确的方法名、函数及正解的代码行数,所以分开使用.效果会更好.

14             log.Debug("This is Debug messages");
15         }

此配置会在程序目录生成一个log4netConfig.xml 文件

使用时会生成一个log4net文件夹,日期名称为日志名称.同时可以写出正确的方法名,类,执行的代码行数. webfrom winfrom 通用.
