Imports System.Collections
Public Class SamplesArrayList
Public Shared Sub Main()
' 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.
myAL.Clear()
' Displays the count, capacity and values of the ArrayList.
Console.WriteLine("After Clear,")
Console.WriteLine(" Count : {0}", myAL.Count)
Console.WriteLine(" Capacity : {0}", myAL.Capacity)
Console.Write(" Values:")
PrintValues(myAL)
' Trim the ArrayList again.
myAL.TrimToSize()
' Displays the count, capacity and values of the ArrayList.
Console.WriteLine("After the second TrimToSize,")
Console.WriteLine(" Count : {0}", myAL.Count)
Console.WriteLine(" Capacity : {0}", myAL.Capacity)
Console.Write(" Values:")
PrintValues(myAL)
End Sub
Public Shared Sub PrintValues(myList As IEnumerable)
Dim obj As [Object]
For Each obj In myList
Console.Write(" {0}", obj)
Next obj
Console.WriteLine()
End Sub
End Class
输出:
Initially, Count : 5 Capacity : 16 Values: The quick brown fox jumps After TrimToSize, Count : 5 Capacity : 5 Values: The quick brown fox jumps After Clear, Count : 0 Capacity : 5 Values: After the second TrimToSize, Count : 0 Capacity : 16 Values:
