How to VB.Net HashTable
In VB.NET, a HashTable is a collection class that represents a collection of key-value pairs, where each unique key maps to a specific value. It provides an efficient way to store and retrieve data based on these key-value associations. The HashTable class is part of the System.Collections namespace in the .NET Framework.
The common functions using in Hashtable are :
The Add function is used to add a key-value pair to the HashTable.
The Remove function is used to remove a key-value pair from the HashTable based on the specified key.
The ContainsKey function checks if a specified key exists in the HashTable.
The Item property (also known as the indexer) allows you to access the value associated with a specific key in the HashTable.
The Count property returns the number of key-value pairs present in the HashTable.
The Clear function removes all key-value pairs from the HashTable, making it empty.
Keys and Values
The Keys and Values properties return collections that contain all the keys and values in the HashTable, respectively.
The ContainsValue function checks if a specified value exists in the HashTable.
The Clone function creates a shallow copy of the HashTable.
The TryGetValue function retrieves the value associated with a specific key from the HashTable, if it exists.

The HashTable in VB.NET provides a powerful data structure for efficient storage and retrieval of data based on key-value associations. It is suitable for various scenarios where fast lookup and dynamic sizing are required.
