名单,其中,T>
从 System.Collections.Generic
做的一切堆栈< T&GT ;
呢,等等 - 他们是基于相同的底层数据结构。在什么条件下是正确的选择堆栈< T>
而不是
List<T>
from System.Collections.Generic
does everything Stack<T>
does, and more -- they're based on the same underlying data structure. Under what conditions is it correct to choose Stack<T>
instead?
您会使用堆栈,如果你有一个需要一个最后在项目的先出集合。名单将允许您访问它的项目在任何索引。还有很多其他方面的差异,但我会说这是最根本的。
You would use stack if you had a need for a Last In First Out collection of items. A list will allow you to access it's items at any index. There are a lot of other differences but I would say this is the most fundamental.

我要说的是,使用堆栈&LT; T&GT;
使你想怎样使用这个code语句。这是一件好事,规划未来,但如果你有需要堆栈&LT; T&GT;
现在,并没有令人信服的理由使用名单,其中, T&GT;
然后,我将与去堆栈&LT; T&GT;
I would say that using Stack<T>
makes a statement about how you want this code to be used. It's always good to plan for the future, but if you have a need for Stack<T>
right now, and no compelling reason to use List<T>
then I would go with Stack<T>
