示例1: Main
' 导入命名空间
Imports System.Collections
Public Class SamplesArrayList
Public Shared Sub Main()
' Creates and initializes a new ArrayList using Insert instead of Add.
Dim myAL As New ArrayList()
myAL.Insert(0, "The")
myAL.Insert(1, "fox")
myAL.Insert(2, "jumps")
myAL.Insert(3, "over")
myAL.Insert(4, "the")
myAL.Insert(5, "dog")
' Creates and initializes a new Queue.
Dim myQueue As New Queue()
myQueue.Enqueue("quick")
myQueue.Enqueue("brown")
' Displays the ArrayList and the Queue.
Console.WriteLine("The ArrayList initially contains the following:")
PrintValues(myAL)
Console.WriteLine("The Queue initially contains the following:")
PrintValues(myQueue)
' Copies the Queue elements to the ArrayList at index 1.
myAL.InsertRange(1, myQueue)
' Displays the ArrayList.
Console.WriteLine("After adding the Queue, the ArrayList now contains:")
PrintValues(myAL)
' Search for "dog" and add "lazy" before it.
myAL.Insert(myAL.IndexOf("dog"), "lazy")
' Displays the ArrayList.
Console.WriteLine("After adding ""lazy"", the ArrayList now contains:")
PrintValues(myAL)
' Add "!!!" at the end.
myAL.Insert(myAL.Count, "!!!")
' Displays the ArrayList.
Console.WriteLine("After adding ""!!!"", the ArrayList now contains:")
PrintValues(myAL)
' Inserting an element beyond Count throws an exception.
Try
myAL.Insert(myAL.Count + 1, "anystring")
Catch myException As Exception
Console.WriteLine("Exception: " + myException.ToString())
End Try
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：
The ArrayList initially contains the following: The fox jumps over the dog The Queue initially contains the following: quick brown After adding the Queue, the ArrayList now contains: The quick brown fox jumps over the dog After adding "lazy", the ArrayList now contains: The quick brown fox jumps over the lazy dog After adding "!!!", the ArrayList now contains: The quick brown fox jumps over the lazy dog !!! Exception: System.ArgumentOutOfRangeException: Insertion index was out of range. Must be non-negative and less than or equal to size.
