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"(有时也称为向量")是非常好的数据结构.只是ArrayList是在C#中应避免的类.
"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，从而破坏类型安全性.
改为使用List<T>.
The reason is that it isn't generic, so you can store any object inside it, breaking type-safety.
Use List<T> instead.
