在回答this的问题，我注意到，我得到了下面的对话，同时atempting移动光标，而异常正在处理的：

  

无法下一条语句设置到此位置。放松调用堆栈的尝试失败。

     

解约是不可能在下列情况下：

        在调试是通过刚刚在时间的调试启动。    开卷正在进行中   系统System.StackOverflowException或System.Threading.ThreadAbortException异常被抛出。   

究竟什么是开卷

解决方案

这是我的！

没有，在这种情况下它通常是指通过烟囱加强，去除连续帧，直到你回来到所需水平的过程。

While answering this question I noticed that I got the following dialog while atempting to move the "cursor" while an exception was being handled:

Unable to set the next statement to this location. The attempt to unwind the callstack failed.

Unwinding is not possible in the following scenarios:

Debugging was started via Just-In-Time debugging. An unwind is in progress A System.StackOverflowException or System.Threading.ThreadAbortException exception has been thrown.

What exactly is an unwind?

解决方案

It's me!

No, in this context it typically refers to the process of stepping through a stack, removing successive frames until you've come back to the desired level.
