推荐答案

不能混合使用堆栈，除非您弹出所有项目，对它们重新排序，然后再次将它们推回. 根据定义，被压入堆栈的第一个项目是最后一个被压出的项目，被压入堆栈的最后一个是弹出的第一个项目.
想想一堆硬币:您只能取下最上面的硬币而不会塌陷.如果要重新排序硬币，则必须将它们全部删除，然后以不同的顺序重新堆叠它们.

Stacks cannot be mixed, unless you pop all the items off, reorder them, and then push them back on again.
By definition, the first item pushed onto a stack is the last item out, and the last item pushed on is the first popped off.
Think of a pile of coins: you can only take the top coin off without the pile collapsing. If you want to re-order the coins, you must remove them all, and re-stack them in a different order.

为此使用List<T>.您将具有随机访问权限，并且可以通过在末尾添加和删除项来像堆栈一样使用它.

Uses a List<T> for that. You will have random access and it can be used like a stack by adding and removing items at the end.
