VB.NET中的集合类型 [英] Collection Types in VB.NET

问题描述

大家好，

我有一些关于arraylist，hashtable，stack，queue，namevaluecollections的概念.

谁能告诉我它们的实际应用.

我在Google中尝试过，但可以找到完全匹配的内容.

感谢您的时间.

Hello All,

I got some concepts regarding arraylist, hashtable, stack, queue, namevaluecollections.

Could anyone tell me the practical applications of each.

I tried in google but could find exact match.

Thanks for your time.

推荐答案

ArrayList是任何类型的对象的集合，由于装箱和拆箱的性能而不能使用，应该使用List< ; T>反而.通常，您可以使用它来按原样存储和迭代.

Hashtable是基于密钥的快速存储和检索的集合.

Stack是后进先出结构.

Queue是先进先出结构.

NameValueCollection or Dictionary非常类似于HashTable.

ArrayList is a collection for any type of object, which should not be used because of boxing and unboxing performance, you should use List<T> instead. You usually use this for storing and iterating over as is.

Hashtable is a collection for rapid storing and retrieval based on the key.

Stack is a Last in First Out structure.

Queue is a First in First Out structure.

NameValueCollection or Dictionary is much like a HashTable.
