Question

首先，在Program.Program()静态构造函数中，我有这段代码：

AppDomain.CurrentDomain.UnhandledException += (s, eargs) =>
    LogException((Exception)eargs.ExceptionObject);
Application.ThreadException +=
    (s, eargs) => LogException(eargs.Exception);

然后，如果我故意做（例如）除零，它就会被抓住。但是，线程循环中没有其他异常被捕获，就像这一个 - 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，系统会静默地吞下它并且我无法记录它。

事实证明，在BindingComplete事件中可以看到我失去的大多数异常。它必须这样做。

Application.ThreadException和AppDomain.CurrentDomain.UnhandledException都不受尊重
