示例1: SamplesQueue
' 导入命名空间
Imports System.Collections
Public Class SamplesQueue
Public Shared Sub Main()
' Creates and initializes a new Queue.
Dim myQ As New Queue()
myQ.Enqueue("The")
myQ.Enqueue("quick")
myQ.Enqueue("brown")
myQ.Enqueue("fox")
' Displays the Queue.
Console.Write("Queue values:")
PrintValues(myQ)
' Removes an element from the Queue.
Console.WriteLine("(Dequeue) {0}", myQ.Dequeue())
' Displays the Queue.
Console.Write("Queue values:")
PrintValues(myQ)
' Removes another element from the Queue.
Console.WriteLine("(Dequeue) {0}", myQ.Dequeue())
' Displays the Queue.
Console.Write("Queue values:")
PrintValues(myQ)
' Views the first element in the Queue but does not remove it.
Console.WriteLine("(Peek) {0}", myQ.Peek())
' Displays the Queue.
Console.Write("Queue values:")
PrintValues(myQ)
End Sub
Public Shared Sub PrintValues(myCollection As IEnumerable)
Dim obj As [Object]
For Each obj In myCollection
Console.Write(" {0}", obj)
Next obj
Console.WriteLine()
