log4net配置

浏览数：33 / 时间：2015年06月09日

mysql数据库，创建这个表

DROP TABLE IF EXISTS `t_errorlog`;
CREATE TABLE `t_errorlog` (
`rowid` int(11) NOT NULL AUTO_INCREMENT,
`log_date` datetime DEFAULT NULL COMMENT ‘log时间‘,
`Thread` varchar(255) DEFAULT NULL COMMENT ‘线程‘,
`Level` varchar(100) DEFAULT NULL COMMENT ‘级别‘,
`logger` varchar(510) DEFAULT NULL COMMENT ‘名称空间‘,
`message` longtext COMMENT ‘出現錯誤讯息‘,
`method` varchar(50) DEFAULT NULL COMMENT ‘出错的方法‘,
PRIMARY KEY (`rowid`)
) ENGINE=InnoDB AUTO_INCREMENT=1403 DEFAULT CHARSET=utf8;

1.第一步：把log4net加入到引用

2.第二步：配置web.config 可以配置成数据库或者文件或者操作系统事件里面

3.第三步：

如果是网站：

MVC中在global.asax里面新增配置

void Application_Start(object sender, EventArgs e)

{

// 在应用程序启动时运行的代码

log4net.Config.XmlConfigurator.Configure();

}

如果是web项目和winform项目或者控制台项目：

要在AssemblyInfo.cs 新增

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)] //当把东西写到web.config中时,改为web.config ----可以

或者：[assembly: log4net.Config.XmlConfigurator()] （把log4net的配置配置在web的配置文件时）

4.第四步:

try
            {
                string a = "1a2b3c";
                int abc = Convert.ToInt32(a);
            }
            catch (Exception ex)
            {
                Admin.gigade.Log4NetCustom.LogMessage logMessage = new Admin.gigade.Log4NetCustom.LogMessage();
                logMessage.Content = string.Format("TargetSite:{0},Source:{1},Message:{2}", ex.TargetSite.Name, ex.Source, ex.Message);
                logMessage.MethodName = System.Reflection.MethodBase.GetCurrentMethod().Name;
                log.Error(logMessage);
            }

5.第五步

Log4NetCustom文件夹

CustomLayout.cs 类

{
    public class CustomLayout : log4net.Layout.PatternLayout
    {
        public CustomLayout()
        {
            this.AddConverter("property", typeof(MyMessagePatternConverter));
        }
    }
}

LogMessage.cs 类

using System;
using System.Collections.Generic;
using System.Linq;

{
    public class LogMessage
    {
        private string m_MethodName;
        private string m_Content;
        public LogMessage()
        {
        }
        public LogMessage(string methodName, string content)
        {
            m_MethodName = methodName;
            m_Content = content;
        }
        public string MethodName
        {
            get
            {
                return m_MethodName;
            }
            set
            {
                m_MethodName = value;
            }
        }
        public string Content
        {
            get
            {
                return m_Content;
            }
            set
            {
                m_Content = value;
            }
        }
    }
}

MyMessagePatternConverter.cs 类

            if (Option != null)
            {

                WriteObject(writer, loggingEvent.Repository, LookupProperty(Option, loggingEvent));
            }
            else
            {
                // Write all the key value pairs
                WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
            }
