c＃先进先出吗？ 找不到，不知道在哪里看

Question

I know exactly what I am looking for, but not how to ask for it in a search engine. I want a collection that can hold any number of objects including duplicates and allows for them to be pulled out randomly. Similar to a deck of cards.

I don't know what this kind of collection would be called in c#. I imagined FIAO(First In Any Out) but that pulls up nothing. Some direction would be appreciated.

Answer 1

我认为您正在寻找ConcurrentBag-我不确定该数据结构是否存在非并行版本。

Answer 2

A Dictionary does not guarantee any particular order of retrieval, with the Keys collection not being ordered. You could keep an incrementing count in the value to signify duplicates.
