The Hashtable class represents a collection of key-and-value pairs that are organized based on the hash code of the key. It uses the key to access the elements in the collection.
A hashtable is used when you need to access elements by using key, and you can identify a useful key value.
Each item in the hashtable has a key/value pair. The key is used to access the items in the collection.
