问题描述

在 dotNet 中,一行抛出异常并被捕获,我如何确定哪个文件中的哪一行抛出了异常?看起来比较简单,但我想不通...

In dotNet a line throws an exception and is caught, how can I figure out which line in which file threw the exception? Seems relatively straightforward, but I can't figure it out...

推荐答案

只有在有可用的调试符号时才能这样做.

You can only do it if you have debug symbols available.

catch(Exception ex) {
    // check the ex.StackTrace property
}

如果你想在 VS 中调试这样的情况,你最好只在 Exceptions 中勾选 Common Language Runtime ExceptionsThrown 复选框Debug 菜单中的对话框.一旦抛出异常,调试器就会中断,即使它位于 try 块中.

If you want to debug such a situation in VS, you'd better just check Thrown checkbox for Common Language Runtime Exceptions in Exceptions dialog located in Debug menu. The debugger will break as soon as the exception is thrown, even if it's in a try block.
