所有这些解决方案都非常难看。一个需要列出所有进程并将其中一个进程标识为刚刚启动的进程。另一个人可以依赖私人字段，你可以通过反思访问它。



想想另一件事：也许你真的没有需要身份证？如果您解释为什么认为您需要它，我们可以为您提供更好的建议。

All those solutions are pretty ugly. One requires listing all processes and identifying the one of them as the one you just started. Another one can rely on private field, which you can access by reflection.

Think about one different thing: maybe you don't really need ID? If you explain the reason why do you think you need it, we can advise you something better.
