I'm working on enhancing the platforms in my company and during my research, I've come across a lot of comments from people saying that ArrayLists should be avoided. However, they never gave much explanation why and I can't find any articles about why they're so awful.

推荐答案

Arraylists"(有时也称为vectors")是完美的数据结构;只是 ArrayList 是 C# 中应该避免的类.

"Arraylists" (also sometimes called "vectors") are perfectly fine data structures; it's just that ArrayList is a class that should be avoided in C#.

原因是它不是通用的,因此您可以在其中存储任何 object,从而破坏了类型安全性.
使用 List 代替.

The reason is that it isn't generic, so you can store any object inside it, breaking type-safety.
Use List<T> instead.
