示例1: Example
' 导入命名空间
Imports System.Collections.Generic
Module Example
Sub Main
Dim numbers As New Queue(Of String)
numbers.Enqueue("one")
numbers.Enqueue("two")
numbers.Enqueue("three")
numbers.Enqueue("four")
numbers.Enqueue("five")
' A queue can be enumerated without disturbing its contents.
For Each number As String In numbers
Console.WriteLine(number)
Next
Console.WriteLine(vbLf & "Dequeuing '{0}'", numbers.Dequeue())
Console.WriteLine("Peek at next item to dequeue: {0}", _
numbers.Peek())
Console.WriteLine("Dequeuing '{0}'", numbers.Dequeue())
' Create a copy of the queue, using the ToArray method and the
' constructor that accepts an IEnumerable(Of T).
Dim queueCopy As New Queue(Of String)(numbers.ToArray())
Console.WriteLine(vbLf & "Contents of the first copy:")
For Each number As String In queueCopy
Console.WriteLine(number)
Next
' Create an array twice the size of the queue, compensating
' for the fact that Visual Basic allocates an extra array
' element. Copy the elements of the queue, starting at the
' middle of the array.
Dim array2((numbers.Count * 2) - 1) As String
numbers.CopyTo(array2, numbers.Count)
' Create a second queue, using the constructor that accepts an
' IEnumerable(Of T).
Dim queueCopy2 As New Queue(Of String)(array2)
Console.WriteLine(vbLf & _
"Contents of the second copy, with duplicates and nulls:")
For Each number As String In queueCopy2
Console.WriteLine(number)
Next
Console.WriteLine(vbLf & "queueCopy.Contains(""four"") = {0}", _
queueCopy.Contains("four"))
Console.WriteLine(vbLf & "queueCopy.Clear()")
queueCopy.Clear()
Console.WriteLine(vbLf & "queueCopy.Count = {0}", _
queueCopy.Count)
End Sub
End Module输出：
one
two
three
four
five
Dequeuing 'one'
Peek at next item to dequeue: two
Dequeuing 'two'
Contents of the copy:
three
four
five
Contents of the second copy, with duplicates and nulls:
three
four
five
queueCopy.Contains("four") = True
queueCopy.Clear()
queueCopy.Count = 0
