log4net - 为什么 log4net 不记录我的堆栈跟踪？

Question

使用首选形式

_log.Error("Message", exception)

不记录我的堆栈跟踪。为了解决这个问题，我必须确保 .ToString() 通过执行以下操作来调用异常。

_log.Error("Message" + exception);

但我知道那是错误的，只是我无法使正确的版本工作。我需要在我的 log4net.xml 文件中添加一个特殊的行来完成这项工作吗？

I wanted to provide my eventual answer, just for reference. I had implemented an asynchronous appender scheme for log4net using my answer to the SO question How do I create an asynchronous wrapper for log4net?

I noted in my response that you need to be careful about the FixFlags, because anything not in the FixFlags will get dropped from the original logging event. Unfortunately, I did not add FixFlags.Exception to my original solution, so any exceptions generated get dropped during the forwarding process.

Changing my FixFlags from

loggingEvent.Fix = FixFlags.ThreadName;

To

loggingEvent.Fix = FixFlags.ThreadName | FixFlags.Exception;

Fixed the issue.
