Please help me to understand this code, not understanding what it's doing exactly?

推荐答案

这是一个基本的 foreach 循环：Controls集合中的每个对象将依次进入变量 c ，并且将使用该值执行循环体。在循环中，集合中的当前Control实例将在其Click事件中添加 ClickCounter 处理程序。



你应该能够自己解决这个问题：如果你不能，你需要在课堂上多加注意！

It's a basic foreach loop: each object in the Controls collection will "go into" the variable c in turn and the loop body will be executed with that value. Inside your loop the current Control instance from the collection will have the ClickCounter handler added to its Click event.

You should be able to work that out for yourself: if you can't you need to pay more attention in class!
