【问题描述】:
首先,在Program.Program() 静态构造函数中,我有以下代码:
AppDomain.CurrentDomain.UnhandledException += (s, eargs) =>
LogException((Exception)eargs.ExceptionObject);
Application.ThreadException +=
(s, eargs) => LogException(eargs.Exception);
然后,如果我故意(例如)除以零,它就会被捕获。但是,线程循环中的其他异常都没有被捕获,就像这个 - 它的堆栈跟踪是:

当ReflectPropertyDescriptor 调用我的代码并且我抛出一个自定义异常时,系统会默默吞下它,我无法记录它。
【问题讨论】:
-
您是在 64 位操作系统上运行它吗? Ctrl+F5启动时会不会爆炸?
-
是的……为什么?这会以某种方式干扰异常处理吗?
-
不,在不调试的情况下运行不会失败。内部会抛出异常,但没有一个是未处理的。
-
这是一个众所周知的问题,调试器和 Windows 之间的不愉快交互,他们无法弄清楚如何修复。项目 + 属性,编译选项卡,平台目标 = x86 来解决它。保持 Release 版本的设置不变是可以的。
-
这不是问题。它也发生在 release+x86 上。
