C＃：应该所有的异常被捕获 [英] C#: should all exceptions be caught

问题描述

如果所有的异常可以在C＃程序捕获，或者有一些例外（如堆栈溢出，内存等）的，你应该让程序崩溃，因为没有办法从他们恢复<？ / p>

解决方案

您应该只抓到，你是能够处理异常。决不曾经捕获异常，什么也不做。尽最大努力保持异常从未然。因为异常产生性能上的惩罚，由于堆栈跟踪这是在.net中尤其重要。

Should all exceptions be caught in a C# program, or are some exceptions (such as stack overflow, out of memory etc.) ones that you should allow the program to crash on because there is no way to recover from them?

解决方案

You should only catch exceptions that you are able to handle. Never ever catch exceptions and do nothing. Do your best to keep the exception from occurring in the first place. This is especially important in .Net because exceptions incur a penalty in performance due to the stack trace.
