Question

我正在尝试将新的滚动文件appender添加到现有的log4net配置中。我一直在关注S.O.的问题。并查看文档，但我似乎无法看到我的问题在哪里。

问题是它创建了文件但从不写入文件。我能想到的是，我以某种方式误解了层次结构是如何运作的？如果我附加了一个调试器，我可以看到该行被写入控制台，但即使我进行了测试部署，日志文件文档也从未写入任何内容。还有其他问题，但是他们都有关于levelMin或类似的问题。我已经尝试将配置设置为ALL，也没有帮助。

这是完整的配置，所以你可以看到我在说什么。

这是代码示例。

 private static readonly HALogger Logger = new HALogger("DocumentImportLogger");
//which calls 
        public HALogger(string loggerName)
        {
            _logger = LogManager.GetLogger(loggerName);
        }

//Then to log.
    Logger.Info(string.Format("Checking for new documents - LastDocumentId: {0}", LastDocInfo.LastDocumentId));

您的配置文件对我来说很好。

问题是log4net在默认情况下默默地忽略配置错误而只是默默地失败 - 这对于日志记录框架来说是一个明智的设计选择，但有时会令人沮丧。

您可以尝试启用内部调试并以编程方式检查配置错误。

请参阅the log4net faq =＆gt;相关部分是：

“How do I enable log4net internal debugging?”

“How can I evaluate configuration errors at runtime?”

另外，请添加一个代码示例，说明如何获取记录器并尝试写入。

new rollingFileAppender创建了该文件，但从未写入该文件
