“on error goto”或“尝试捕获” [英] "on error goto" or "try catch"

问题描述

作为一名前VB程序员，我习惯了on error goto-errorhandling。我实际上所有的VB.NET样本都可以看到，人们可以使用尝试 -

catch - 错误处理。

两者中哪一个最好？是否有充分的理由使用Try-Catch？

请问on error goto将来消失？使用trey-catch有什么合理的理由吗？编程是更好吗？等等:-)


我对on error goto更加舒服，主要是因为我使用了

给它我猜。任何有关此主题的帮助或反馈都会很好！


提前致谢！

Hi,

As a former VB-programmer I''m used to the "on error goto"-errorhandling. I
see that in actually all the VB.NET-samples I can fin people use the "Try -
catch"-errorhandling.

Which of the two is the best? Are there good reasons to use the Try-Catch?
Will the "on error goto" disapear in the future? Are there any logical
reasons to use trey-catch? Is it ''better'' programming? etc etc :-)

I''m jsut more comfortable with the "on error goto", mostly because I''m used
to it I guess. Any help or reflectiosn regarding this subject would be nice!

Thanks in advance!

推荐答案

Hi Dragu ，


如果你习惯了


的可能性尝试

Catch（倍数

结束尝试

最后


从那个嵌套的可能性，你不相信你能做到

它使用on error goto


我希望这能给出一个想法吗？

Hi Dragu,

If you are used to the possibilties from the

Try
Catch (multiples
End Try
Finally

And the nesting posibilities from that, you would not believe you could do
it with the "on error goto"

I hope this gives an idea?

我是VB程序员和我习惯了但是现在试试..抓住是

更好。

通过这个声明你可以捕捉所有不同类型的例外和

为每个人执行特定的操作。

我希望这对你有用

Hi,
I was a VB-programmer to and I was used to on error but now Try .. catch is
better.
With this statement you can catch all different types of exceptions and
perform a specific action for each one.
I hope this will be usefull for you

但是：_为什么它更好？在某些情况下，IMO会更好，因为它会使代码更加紧凑，但有时，例如在强制执行一个大型算法时，它会非常烦人，因为它会阻止读者看到代码的含义。


只是想一想。

But: _Why_ exactly is it better? It''s IMO better in some cases because it
leaves code more compact, but sometimes, for example when impementing a
large algorithm, it''s very annoying because it will prevent the reader
from seeing the point of the code.

Just a thought.
