' Creates and initializes a new ArrayList.
Dim myAL As New ArrayList()
myAL.Add("The")
myAL.Add("quick")
myAL.Add("brown")
myAL.Add("fox")
myAL.Add("jumps")
' Displays the count, capacity and values of the ArrayList.
Console.WriteLine("Initially,")
Console.WriteLine(" Count : {0}", myAL.Count)
Console.WriteLine(" Capacity : {0}", myAL.Capacity)
Console.Write(" Values:")
PrintValues(myAL)
' Trim the ArrayList.
myAL.TrimToSize()
' Displays the count, capacity and values of the ArrayList.
Console.WriteLine("After TrimToSize,")
Console.WriteLine(" Count : {0}", myAL.Count)
Console.WriteLine(" Capacity : {0}", myAL.Capacity)
Console.Write(" Values:")
PrintValues(myAL)
' Clear the ArrayList.
