WPF 如何在单独的配置文件中使用Log4net

引用log4net包

NuGet程序包 -----》搜索log4net -------》点击安装

创建单独的配置文件

1. log4net.config
2. 文件内容(日志文件放在DEBUG)

<log4net>

	<root>
		<level value="DEBUG" />
		<appender-ref ref="DebugRollingFileAppender" />
		<appender-ref ref="InfoRollingFileAppender" />

	</root>

使用log4

在要用到log4的地方命名空间上边加上[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

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

namespace SlicingMachine
{
    public partial class App : Application
    {
        public static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

        protected override void OnStartup(StartupEventArgs e)
        {
            log4net.Config.XmlConfigurator.Configure();
            base.OnStartup(e);
            log.Info("==Startup=====================>>>");
        }

        protected override void OnExit(ExitEventArgs e)
        {
            log.Info("<<<========================End==");
            base.OnExit(e);
        }
    }
}

public void SendData(int index = 0)
{
    App.log.Debug("发生错误==============================");

}
