推荐答案

转到Debug / Windows / Exception Settings并在Common Language Runtime Exceptions下检查FileNotFoundException。抛出异常后，调试器将停止运行，您将能够看到发生了什么。

Go to Debug/Windows/Exception Settings and check FileNotFoundException under Common Language Runtime Exceptions. The debugger will stop when the exception is thrown and you will be able to see what is going on.

请注意，在异常中预期并处理异常并不罕见。某些情况下。您可能会发现该异常是预期的和已处理的，无需执行任何操作即可对其进行修复。

Note that it is not unusual for exceptions to be expected and handled in some cases. You may find that the exception is expected and handled, and nothing needs to be done to fix it.
