log4net - “log4net：错误 XmlHierarchyConfigurator：找不到属性 [评估器] 在 [log4net.Appender.RollingFileAppender] 上设置对象”

Question

即使配置文件中提供了 evaluator 属性，log4net 配置也会出现以下错误。你能帮忙吗？

evaluator只能在派生自的附加程序上 配置BufferingAppenderSkeleton：

• AdoNetAppender,
• BufferingForwardingAppender
• RemotingAppender
• SmtpAppender
• SmtpPickupDirAppender.

由于RollingFileAppender不是派生自BufferingAppenderSkeleton没有这样的属性来配置。

要解决此问题，请将其从配置中删除。
