类库里面添加日志记录 log4net

第一步：

新建一个公共类库common,添加CustomLog4jLogger.cs 并引用log4net.dll

/// <summary>
    /// 日志记录
    /// </summary>
    public class CustomLog4jLogger
    {
        /// <summary>
        /// 日志
        /// </summary>
        public static ILog Logger = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

        /// <summary>
        /// 日志
        /// </summary>
        /// <param name="funcstr">方法名称</param>
        /// <param name="message">日志描述</param>
        /// <param name="args">方法参数</param>
        /// <param name="type">类别，1：错误日志，2:操作日志</param>
        private static void Log(string apikey, string funcstr, string message, string args, int type)
        {
            switch (type)
            {
                case 1:
                    Logger.Error(string.Format("Func:{0} | Error:{1} | Args:{2}", funcstr, message, args));
                    break;
                case 2:
                    Logger.Info(string.Format("Key:{0} | Func:{1} | Message:{2}", apikey, funcstr, message));
                    break;
                case 3:
                    Logger.Warn(message);
                    break;
            }
        }
        /// <summary>
        /// 错误日志
        /// </summary>
        /// <param name="funcstr">方法名称</param>
        /// <param name="message">错误信息</param>
        /// <param name="args">方法参数</param>
        public static void LogDebug(string funcstr, string message, string args)
        {
            Log("", funcstr, message, args, 1);
        }
        /// <summary>
        /// 错误日志
        /// </summary>
        /// <param name="funcstr">方法名称</param>
        /// <param name="message">错误信息</param>
        public static void LogDebug(string funcstr, string message)
        {
            LogDebug(funcstr, message, "");
        }
        /// <summary>
        /// 错误日志
        /// </summary>
        /// <param name="message">错误信息</param>
        public static void LogDebug(string message)
        {
            LogDebug("", message);
        }

        /// <summary>
        /// 运行日志
        /// </summary>
        /// <param name="message">运行信息</param>
        public static void LogInfo(string message)
        {
            LogInfo("", message);
        }
        /// <summary>
        /// 运行日志
        /// </summary>
        /// <param name="funcstr">方法名称</param>
        /// <param name="message">运行信息</param>
        /// <param name="args">方法参数</param>
        public static void LogInfo(string funcstr, string message)
        {
            LogInfo("", funcstr, message);
        }
        /// <summary>
        /// 运行日志
        /// </summary>
        /// <param name="apikey">应用的apikey</param>
        /// <param name="funcstr">方法名称</param>
        /// <param name="message">运行信息</param>
        /// <param name="args">方法参数</param>
        public static void LogInfo(string apikey, string funcstr, string message)
        {
            Log(apikey, funcstr, message, "", 2);
        }

        public static void LogEvent(string message)
        {
            Log("", "", message, "", 3);
        }
    }

　　第二步：

在需要记录日志的类库里，引用common类库，调用：

CustomLog4jLogger.LogInfo("xxxxxx");
第三步：
在调用类库的程序里添加log4net.config(在附件里)并引用log4net.dll
程序调用：

  static void Main(string[] args)
        {
            try
            {
                log4net.Config.XmlConfigurator.Configure(new FileInfo(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, "log4net.config")));
}
}
