log4net 配置

CS 程序

1. 进入需要配置 log4net 的项目目录下，安装或引用 log4net；

   • 右键-管理 NuGet 程序包，搜索 log4net 并安装；
   • 引用已下载的 log4net.dll 文件。

2. 程序启动时读取 log4net 的配置文件,在 AssemblyInfo.cs 中加入 [assembly: log4net.Config.XmlConfigurator(ConfigFile = "app.config", Watch = true)]；

3. 在原有的 app.config 上加入 log4net 的输出配置信息；

     <configuration>
     <!--log4net-->

       <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false"/>

4. 如需读取新的配置文件，可在程序的调用方法前加入 log4net.Config.XmlConfigurator.Configure(new FileInfo("log4net.xml"))强制读取新的配置文件。
