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