Imports System.Collections
Public Class SamplesHashtable
Public Shared Sub Main()
' Creates and initializes a new Hashtable.
Dim myHT As New Hashtable()
myHT.Add("1a", "The")
myHT.Add("1b", "quick")
myHT.Add("1c", "brown")
myHT.Add("2a", "fox")
myHT.Add("2b", "jumps")
myHT.Add("2c", "over")
myHT.Add("3a", "the")
myHT.Add("3b", "lazy")
myHT.Add("3c", "dog")
' Displays the Hashtable.
Console.WriteLine("The Hashtable initially contains the following:")
PrintKeysAndValues(myHT)
' Removes the element with the key "3b".
myHT.Remove("3b")
' Displays the current state of the Hashtable.
Console.WriteLine("After removing ""lazy"":")

End Sub
Public Shared Sub PrintKeysAndValues(myHT As Hashtable)
For Each de As DictionaryEntry In myHT
