log4net 发布到生产环境不写日志的解决方法

1、升级到log4net的最新版

PM下执行

Install-Package log4net

还是无法解决的，使用下面的方法

2、使用Nlog替换之，详见https://github.com/NLog/NLog/wiki/Tutorial

NLog使用方法比log4net更为简单，配置文件如下，如果成windows程序需将NLog.config自动复制到bin下面

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
 3       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4       xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
 5       autoReload="true"
 6       throwExceptions="false"
 7       internalLogLevel="Off" internalLogFile="F:\temp\20160907\NLog\log\nlog-internal.log">

26     <!--

28     <target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}.log"
29             layout="${longdate} ${uppercase:${level}} ${message}" />
30     -->
31       <target name="logfile" xsi:type="File" fileName="${basedir}/logs/${shortdate}.log" />
32       <target name="console" xsi:type="ColoredConsole" />
33   </targets>
34
35   <rules>
36       <!-- add your logging rules here -->
37
38       <!--
39     Write all events with minimal level of Debug (So Debug, Info, Warn, Error and Fatal, but not Trace)  to "f"
40     <logger name="*" minlevel="Debug" writeTo="f" />
41     -->
42       <logger name="*" minlevel="Debug" writeTo="logfile" />
43       <logger name="*" minlevel="Info" writeTo="console" />
44   </rules>
45 </nlog>

NLog.config

调用代码：

 1   Logger logger = LogManager.GetCurrentClassLogger();
 2
 3
 4             logger.Trace("Sample trace message");
 5             logger.Debug("Sample debug message");
 6             logger.Info("Sample informational message");
 7             logger.Warn("Sample warning message");
 8             logger.Error("Sample error message");
 9             logger.Fatal("Sample fatal error message");
10
11
12             logger.Info("wilson测试 日志日期：{0}", DateTime.Now);

执行结果，非常漂亮的控制台输出：
