推荐答案

您真的希望我们为您做功课吗.....

你去了:

C#ArrayList [ ^ ]和 C#哈希表 [ ^ ]

Do you really expect us to do your homework for you...ok..

here you go:

C# ArrayList[^] and C# HashTable[^]

Arraylist是对象的集合(可能具有不同的类型).
Arraylist与array非常相似，但是它可以采用不同数据类型的值.
如果要在数组列表中查找内容，则必须遍历数组列表中的每个值，没有更快的出路.

Hashtable也是一个集合，它采用与每个值相对应的键.
如果要在哈希表中查找内容，则不必遍历哈希表中的每个值，而是搜索键值并且速度更快.

Arraylist is a collection of objects(may be of different types).
Arraylist is very much similar to array but it can take values of different datatypes.
If you want to find something in a arraylist you have to go through each value in arraylist, theres no faster way out.

Hashtable is also collection which takes a key corresponding to each values.
If you want to find something in a hashtable you dont have to go through each value in hashtable, instead search for key values and is faster.
