我在VS2013中获得了不同的堆栈跟踪＆＃34; DEBUG - ＆gt;开始调试＆＃34;和＆＃34; DEBUG - ＆gt;启动时无需调试＆＃34;。似乎外部异常正在被删除。
这是我做的事情＆＃34; DEBUG - ＆gt;开始调试＆＃34; （注意外部异常）：

我很难理解为什么会发生这种情况。为什么在使用调试器运行或在没有调试器的情况下运行时堆栈跟踪会发生变化？
答案 0 :(得分：0)
在visual studio中，如果你转到菜单Debug - ＆gt;例外情况，您将看到包含公共语言运行时异常，托管调试助手等异常的表单。根据此设置，通常情况下堆栈跟踪之间的差异来自Visual Studio，它可能会提前中断，或者根本不会中断，只会继续尝试运行。如果你想要更多的细节，那么希望其他人可以回答。我只知道这通常是堆栈跟踪不同的原因。
