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.

Solution 1

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.
