for和foreach有什么区别？ [英] What is the difference between for and foreach?

问题描述

和 foreach 循环之间的主要区别是什么？

在哪些情况下，我们可以使用作为而不是 foreach ，反之亦然。 b
$ b

能用简单的程式显示吗？

两者对我来说都是一样的。我不能区分它们。

a foreach 循环是一个构造，它说：对这个IEnumerable中的每个值/对象执行这个操作

What is the major difference between for and foreach loops?

In which scenarios can we use for and not foreach and vice versa.

Would it be possible to show with a simple program?

Both seem the same to me. I can't differentiate them.

解决方案

a for loop is a construct that says "perform this operation n. times".

a foreach loop is a construct that says "perform this operation against each value/object in this IEnumerable"
