一、下载并引用log4net.dll

二、编写通用类

1  public static class AppLog 2     { 3         private static ILog log; 4  5         static AppLog() 6         {
     7             XmlConfigurator.ConfigureAndWatch(new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config")); 8            // var logCfg = new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config"); 9             log = LogManager.GetLogger(typeof(AppLog));10         }11 12         public static void Debug(object message)13         {14             log.Debug(message);15         }16 17         public static void DebugFormatted(string format, params object[] args)18         {19             log.DebugFormat(format, args);20         }21 22         public static void Info(object message)23         {24             log.Info(message);25         }26 27         public static void InfoFormatted(string format, params object[] args)28         {29             log.InfoFormat(format, args);30         }31 32         public static void Warn(object message)33         {34             log.Warn(message);35         }36 37         public static void Warn(object message, Exception exception)38         {39             log.Warn(message, exception);40         }41 42         public static void WarnFormatted(string format, params object[] args)43         {44             log.WarnFormat(format, args);45         }46 47         public static void Error(object message)48         {49             log.Error(message);50         }51 52         public static void Error(object message, Exception exception)53         {54             log.Error(message, exception);55         }56 57         public static void ErrorFormatted(string format, params object[] args)58         {59             log.ErrorFormat(format, args);60         }61 62         public static void Fatal(object message)63         {64             log.Fatal(message);65         }66 67         public static void Fatal(object message, Exception exception)68         {69             log.Fatal(message, exception);70         }71 72         public static void FatalFormatted(string format, params object[] args)73         {74             log.FatalFormat(format, args);75         }

 

三、编写配置文件

注意：配置文件在属性上面，要设置成 “始终复制”

 

四、启动设置

 在Properties下的AssemblyInfo.cs文件中加入

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", ConfigFileExtension = "config", Watch = true)]

五、调用

AppLog.Info("开始关闭sqlExecute");
