Log4net日志

log4net简介(摘抄于百度百科):

     log4net库是Apache log4j框架在Microsoft .NET平台的实现,是一个帮助程序员将日志信息输出到各种目标(控制台、文件、数据库等)的工具。
     log4net是Apache软件基金会Apache Logging Services工程的一部分。Apache日志服务工程致力于为程序调试和审计提供跨语言的日志服务。

log4net特征

  • 支持多数框架
  • 可输出日志到多种目标
  • 层级日志体系
  • 可使用XML配置
  • 可动态配置
  • 记录上下文信息
  • 被检验过的体系
  • 模块化和可扩展化设计
  • 灵活、高性能

3、IWebLog定义接口

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using log4net;

namespace logertest.Func
{
    public interface IWebLog : ILog
    {
        void Info(string username, string logtype, string clientIP, string requestUrl, object message);
        void Info(string username, string logtype, string clientIP, string requestUrl, object message, Exception t);

        void Warn(string username, string logtype, string clientIP, string requestUrl, object message);
        void Warn(string username, string logtype, string clientIP, string requestUrl, object message, Exception t);

        void Error(string username, string logtype, string clientIP, string requestUrl, object message);
        void Error(string username, string logtype, string clientIP, string requestUrl, object message, Exception t);

        void Fatal(string username, string logtype, string clientIP, string requestUrl, object message);
        void Fatal(string username, string logtype, string clientIP, string requestUrl, object message, Exception t);

        void Debug(string username, string logtype, string clientIP, string requestUrl, object message);
        void Debug(string username, string logtype, string clientIP, string requestUrl, object message, Exception t);

    }
}

4、WebLogImpl实现IWebLog定义的接口

        }

        public void Fatal(string username, string logtype, string clientIP, string requestUrl, object message)

        }

        public void Fatal(string username, string logtype, string clientIP, string requestUrl, object message, System.Exception t)
