解决方案

你好tshad，


IL输出与返回没有区别。和退出子当

用于子时。但是，为了便于阅读，我建议使用Exit Sub。

返回表示将一个值推回给调用者，因为一个子元素没有
有一个返回值，不太明确的意图。

嗯，你可以将''Return''解释为Return something。或者返回

到某物。

Is there any difference between Return and Exit Sub?

I have some code that uses both when I have an error in my Sub.

Thanks,

Tom

Hello tshad,

There is no difference in the IL output from "Return" and "Exit Sub" when
used in a sub. However, for readability I would suggtest using Exit Sub.
Return denotes pushing a value back to the caller, which since a sub doesnt
have a return value, makes for a less clear intent.

Tshad,

There should be not any difference although I prefer Exit Sub.

Well, you could interpret ''Return'' either as "Return something" or "Return
to something".
