推荐答案

什么是第一次机会例外?

在调试应用程序时，每当遇到异常时，调试器都会收到通知.此时，应用程序已挂起，调试器决定如何处理异常.通过这种机制的第一次通过被称为第一次机会"异常.根据调试器的配置，它会恢复应用程序并传递异常，或者使应用程序挂起并进入调试模式.如果应用程序处理了该异常，它将继续正常运行.

When an application is being debugged, the debugger gets notified whenever an exception is encountered. At this point, the application is suspended and the debugger decides how to handle the exception. The first pass through this mechanism is called a "first chance" exception. Depending on the debugger's configuration, it will either resume the application and pass the exception on or it will leave the application suspended and enter debug mode. If the application handles the exception, it continues to run normally.
