中止进一步的程序执行

Question

I have a several nested methods in my program. If a deeply nested method errors out in my try block how do i stop further execution and print the error to the console?

Answer 1

Not sure whether I'm understanding your question correctly...

But if you don't want to handle it in the deeper-down code, then don't catch it (or catch it and re-throw it again).

Exceptions travel up the call stack until something catches them.

Answer 2

You can rethrow the exception within your catch block using throw; . If you let this bubble to the top, your app can handle it and exit.

Answer 3

你可以做的另一件事是将Exception包装在一个自定义异常中，并指示你的不同try catchs重新抛出它，直到它到达你想用来处理它的一个特定的try catch块。
