第一步：

添加并应用Log4net.dll。然后在Web.config文件中添加下面的配置局

复制代码代码如下:
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>

第二步：

新建Log4Net.config的配置文件，并在其中添加下面的配置信息：

复制代码代码如下:
<"1.0" encoding="UTF-8""false">

      <layout type="log4net.Layout.ExceptionLayout" />
    </parameter>
</appender>

</log4net>

第三步：

在Global.asax文件中的Application_Start事件中添加如下代码：

复制代码代码如下:
protected void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
log4net.Config.XmlConfigurator.ConfigureAndWatch(new FileInfo(Server.MapPath("Log4Net.config")));
}

第四步：调用LOG4net 写日志

复制代码代码如下:
protected void Button2_Click(object sender, EventArgs e)
{
ILog logs = LogManager.GetLogger(typeof(TEST));

logs.Fatal("Excption:这里就是要提示的LOG信息");
}

也可以通过写一个LogHelper.cs类进行封装：

复制代码代码如下:
using System;
using System.Collections.Generic;
using System.Web;
using log4net;

namespace SBIT.Web.Class
{
    /// <summary>
    /// 日志辅助类
    /// </summary>
    public class LogHelper
    {
        private static ILog log;
        private static LogHelper logHelper = null;
        /// <summary>
        /// 初始化
        /// </summary>
        /// <returns></returns>
        public static ILog GetInstance()
        {
            logHelper = new LogHelper(null);

            return log;
        }
        /// <summary>
        /// 初始化
        /// </summary>
        /// <param name="configPath"></param>
        /// <returns></returns>
        public static ILog GetInstance(string configPath)
        {
            logHelper = new LogHelper(configPath);

            return log;
        }
        /// <summary>
        /// 构造函数
        /// </summary>
        /// <param name="configPath"></param>
        private LogHelper(string configPath)
        {
            if (!string.IsNullOrEmpty(configPath))
            {
                log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
                log4net.Config.XmlConfigurator.Configure(new System.IO.FileInfo(configPath));
            }
            else
            {
                log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
            }
        }

}
}

通过封装类写日志的方法如下
复制代码代码如下:
private static readonly ILog logs = LogHelper.GetInstance(); //LogManager.GetLogger(typeof(TEST));
        protected void Button2_Click(object sender, EventArgs e)
        {
                logs.Fatal("Excption:这里就是要提示的LOG信息");
        }
