示例1: Example
' 导入命名空间
Imports System.Collections.Generic
Module Example
Sub Main
Dim numbers As New Stack(Of String)
numbers.Push("one")
numbers.Push("two")
numbers.Push("three")
numbers.Push("four")
numbers.Push("five")
' A stack can be enumerated without disturbing its contents.
For Each number As String In numbers
Console.WriteLine(number)
Next
Console.WriteLine(vbLf & "Popping '{0}'", numbers.Pop())
Console.WriteLine("Peek at next item to pop: {0}", _
numbers.Peek())
Console.WriteLine("Popping '{0}'", numbers.Pop())
' Create another stack, using the ToArray method and the
' constructor that accepts an IEnumerable(Of T). Note that
' the order of items on the new stack is reversed.
Dim stack2 As New Stack(Of String)(numbers.ToArray())
Console.WriteLine(vbLf & "Contents of the first copy:")
For Each number As String In stack2
Console.WriteLine(number)
Next
' Create an array twice the size of the stack, compensating
' for the fact that Visual Basic allocates an extra array
' element. Copy the elements of the stack, starting at the
' middle of the array.
Dim array2((numbers.Count * 2) - 1) As String
numbers.CopyTo(array2, numbers.Count)
' Create a second stack, using the constructor that accepts an
' IEnumerable(Of T). The elements are reversed, with the null
' elements appearing at the end of the stack when enumerated.
Dim stack3 As New Stack(Of String)(array2)
Console.WriteLine(vbLf & _
"Contents of the second copy, with duplicates and nulls:")
For Each number As String In stack3
Console.WriteLine(number)
Next
Console.WriteLine(vbLf & "stack2.Contains(""four"") = {0}", _
stack2.Contains("four"))
Console.WriteLine(vbLf & "stack2.Clear()")
stack2.Clear()
Console.WriteLine(vbLf & "stack2.Count = {0}", _
stack2.Count)
End Sub
End Module输出：
five
four
three
two
one
Popping 'five'
Peek at next item to pop: four
Popping 'four'
Contents of the first copy:
one
two
three
Contents of the second copy, with duplicates and nulls:
one
two
three
stack2.Contains("four") = False
stack2.Clear()
stack2.Count = 0
