这实际上是一个效率问题，在链表中插入、删除或移动(而不是简单地交换)元素的开销是最小的，即操作本身是O(1)，而不是O(n)。如果您大量操作数据列表，这可能会产生显著的差异。您可以根据对数据类型的操作方式选择数据类型，并为所使用的算法选择最有效的数据类型。

维基百科上有很好的章节介绍了它们的区别。

Linked lists have several advantages over arrays. Elements can be inserted into linked lists indefinitely, while an array will eventually either fill up or need to be resized, an expensive operation that may not even be possible if memory is fragmented. Similarly, an array from which many elements are removed may become wastefully empty or need to be made smaller. On the other hand, arrays allow random access, while linked lists allow only sequential access to elements. Singly-linked lists, in fact, can only be traversed in one direction. This makes linked lists unsuitable for applications where it's useful to look up an element by its index quickly, such as heapsort. Sequential access on arrays is also faster than on linked lists on many machines due to locality of reference and data caches. Linked lists receive almost no benefit from the cache. Another disadvantage of linked lists is the extra storage needed for references, which often makes them impractical for lists of small data items such as characters or boolean values. It can also be slow, and with a naïve allocator, wasteful, to allocate memory separately for each new element, a problem generally solved using memory pools.

除了插入到列表中间更容易之外——从链表中间删除也比从数组中删除容易得多。

但坦率地说，我从未使用过链表。每当我需要快速插入和删除时，我也需要快速查找，所以我使用HashSet或Dictionary。

这里有一个快速的方法:移除物品更快。

数组Vs链表:

由于内存碎片，阵列内存分配有时会失败。 在数组中缓存更好，因为所有元素都分配了连续的内存空间。 编码比数组更复杂。 与数组不同，在链表上没有大小限制 在链表中插入/删除更快，在数组中访问更快。 从多线程的角度来看，链表更好。
