AssemblyInfo.cs文件下添加

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

添加一个按钮点击事件里加入

         log4net.ILog myLogger = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
            myLogger.Warn("这是一个警告日志");
            myLogger.Info("单击了按钮");
            myLogger.Debug("用Log4Net写入数据库日志");
            myLogger.Error("这是一个错误日志");
            myLogger.Fatal("这是一个致命的错误日志");
            try
            {
                ILog logger = LogManager.GetLogger("LogRecord");
                logger.Debug("用Log4Net写入数据库日志");
                int x = ;
                int y = ;
                throw new Exception("测试错误");
            }
            catch (Exception ex)
            {
                myLogger.Error(ex.Message);
            }
            finally
            {
                label1.Text = DateTime.Now.ToLongTimeString() + ":操作日志已记录完成";
            }
