有关"StackTrace"的问题 [英] A question about "StackTrace"

问题描述

我有一个关于StackTrace的问题.
我正在使用"Embarcadero c ++ builder 2010".
我无法使用Exception类的StackTrace.
StackTrace属性始终使我为NULL.
我想在运行时看到调用堆栈.

请有人帮帮我.

下面是测试代码.
"st"始终为NULL.

Hi,

I have a question about StackTrace.
I am using "Embarcadero c++ builder 2010".
I have failed to use StackTrace of Exception class.
The StackTrace property always gives me NULL.
I want to see call stack while run time.

Please sombody help me.

Below is the test code.
The "st" is always NULL.

void TestFunc(int c)
{
  try
  {
    String ss;
    ss.sprintf(L"%s", 1111111111111111111);
  }
  catch (Exception& e)
  {
    String msg = e.Message;
    String st = e.StackTrace;
  }
}

预先感谢.

Thanks in advance.

推荐答案

必须为:

Must be:

void TestFunc(int c)
{
  try
  {
     int test = 0;
     test = test/test; //throw exception here;
  }
  catch (Exception ^ e)
  {
    String msg = e->Message;
    String st = e->StackTrace;
    //...
  }
}

这个System :: Exception属性只是一个人类可读的字符串，您只能看一下它.
要使用堆栈进行高级操作，请使用System.Diagnostics::StackTrace.

有关一个非常有趣的示例，请参阅我的文章:希望您在这里……只有一次，希望您在这里…只有一次 [ ^ ]: -).

This System::Exception property is just a human-readable string, you cannot do anything but look at it.
For advanced operation with stack use System.Diagnostics::StackTrace.

For a very funny example, please see my article: Wish You Were Here… Only Once, Wish You Were Here… Only Once[^] :-).
