Using a class (User control) in stack

Question

I am sorry if this noob question. So we are learning user controls and this bit of code popped up.

private Stack<MyFirstUserControl1> _myControls = new Stack<MyFirstUserControl1>();
private int _controlsInstantiated = 0; 

Can you use a class within a Stack? Can anyone explain? Noob question I'm sure...

Answer 1

Stack<MyFirstUserControl1>仅表示该集合将为MyFirstControl1类型

Answer 2

堆栈无非就是LIFO队列，因此可以肯定，它只是对象的列表/集合，可以基于后进先出的方式推送和弹出对象，在这种情况下，它是类型MyFirstUserControl1的实例的列表。
