动态加载的 dll 上的 log4net 不记录

如何解决动态加载的 dll 上的 log4net 不记录

> 我有一个在运行时动态加载的 DLL。我的 log4net 在加载 DLL 之前和之后都记录良好，但不是 在 DLL 中记录任何内容都是它自己的。我创建了一个测试存根 使用相同 DLL 的应用程序，它将正常记录。有没有 具体在我需要设置的配置中才能让 log4net 在什么时候工作 动态加载？

        /// <summary>
    /// Setting the Scanning Module
    /// </summary>
    private MyAPpLibrary.Helpers.LoaderAssembly _executingModule;
    public MyAPpLibrary.Helpers.LoaderAssembly executingModule
    {
        get
        {
            if(_executingModule == null)
            {
                
                try
                {
                    _executingModule = (MyAPpLibrary.Helpers.LoaderAssembly)appDomain
                                        .CreateInstanceAndUnwrap(typeof(MyAPpLibrary.Helpers.LoaderAssembly).Assembly.FullName,typeof(MyAPpLibrary.Helpers.LoaderAssembly).FullName);

                    _executingModule.ModuleName = ScanModuleAssembly;
                    _executingModule.LoadAssembly(Path.Combine(Path.Combine(System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath,"Bin",ScanModuleAssembly)));
                    
                }
                catch(Exception er)
                {
                    log.Error(er);
                }

            }

            return _executingModule;
        }
        set
        {
            if ((_executingModule != value))
            {
                _executingModule = value;
            }
        }
    }

调用动态加载DLL

executingModule.ExecuteStaticMethod(ScanModuleAssembly,"FormOCRProcess",objParams);

在加载的 DLL 中设置 log4net。

        private static ILog _log;
    public static ILog log
    {
        get
        {
            if (_log == null)
            {
                log4net.Config.XmlConfigurator.Configure();
                _log = LogManager.GetLogger("ScanningModule");
            }

            return _log;
        }
    }

动态加载的模块 .confg 文件
