当ASP.NET处理未处理的异常时，事件日志消息会扩展

If I throw an unhandled exception from ASP.NET, a warning is added to the eventlog (as expected).

如果我从ASP.NET中抛出未处理的异常,则会向事件日志添加警告(如预期的那样)。

But if the message in the exception contains a %, the message in the eventlog gets garbled:

但是,如果异常中的消息包含%,则事件日志中的消息会出现乱码:

If the Message was

如果消息是

Could not find foo%20bar

the eventlog will read

事件日志将会读取

Could not find foohttp://localhost/testpage.aspxbar

Other numeric values after the % will be converted to other strings.

%之后的其他数值将转换为其他字符串。

It looks like the message gets passed through a printf-statement somewhere on the way.

看起来消息在路上的某个地方通过printf语句传递。

Is this per design? Is there a way to avoid this (besides making sure that exceptions are handled)?

这是每个设计?有没有办法避免这种情况(除了确保处理异常)?

EDIT:

If I look at the XML-view under details in the eventlog, I see:

如果我在事件日志中查看详细信息下的XML视图,我会看到:

<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

</EventData>
</Event>

This looks fine. So it looks like the problem might be in the Event Viewer. What logic converts the XML event data into the formatted data under General?

看起来很好。所以看起来问题可能出在事件查看器中。什么逻辑将XML事件数据转换为General下的格式化数据?
