推荐答案

我认为除了一个漂亮的代码与你相比，你会觉得没什么区别>
第一个选项。


For Each语句也使用IEnumerator接口，但是

简化了你的使用。

I think you will feel no difference other than a beautiful code with the
first option.

The For Each statement also uses the IEnumerator interface, but it
simplifies the use for you.

两个版本都相同。 For Each也使用IEnumerator界面。

Both versions are equal. For Each also uses the IEnumerator interface.
