如何在运行时检测程序是否在抛出异常的情况下执行？ [英] How to detect if a program is executing under a thrown exception at runtime?

问题描述

我可以在运行时在方法Helper（）中检测到程序执行是引发异常的结果吗？

Can I detect at runtime inside method Helper() that the program execution is the result of a thrown exception?

请注意，我的目标是避免扩展Helper（）方法以将异常对象作为输入参数。

Note, my goal is to avoid extending method Helper() to take an exception object as a input pararmeter.

public void MyFunc1()
{
  try
  {
    // some code here that eventaully throws an exception
  }
  catch( Exception ex )
  {
     Helper();
  }
}

public void MyFunc2()
{
   Helper();
}

private void Helper()
{
    // how can I check if program execution is the  
    // result of a thrown exception here.
}

推荐答案

有一个可怕的骇客涉及 Marshal.GetExceptionPointers 和 Marshal.GetExceptionCode 不适用于所有平台，它是：

There is one horrible hack involving Marshal.GetExceptionPointers and Marshal.GetExceptionCode that doesn't work on all platforms here it is:

public static Boolean IsInException()
{
   return Marshal.GetExceptionPointers() != IntPtr.Zero ||
          Marshal.GetExceptionCode() != 0;
}
