WebHashtable in C# is a collection of elements, represented in a key value pair format. The key can be the same, while values differ and the key cannot be null while a value can be. We implemented an example of functions like remove, clear, and print. Hashtable has a speed advantage over other data structures. WebA hash code is a numeric value that is used to insert and identify an object in a hash-based collection such as the Dictionary class, the Hashtable class, or a type derived from the DictionaryBase class. The GetHashCode method provides this hash code for algorithms that need quick checks of object equality.
