我正在寻找在VBA for Excel中实现堆栈类。我想使用先进先出结构。有人以前遇到这个问题吗？你知道外部库处理结构，如Stack，Hastable，Vector ...（除了原来的Excel Collection等...）

I'm looking to implement a "Stack" Class in VBA for Excel. I want to use a Last In First Out structure. Does anyone came across this problem before ? Do you know external libraries handling structure such as Stack, Hastable, Vector... (apart the original Excel Collection etc...)

谢谢

推荐答案

这是一个非常简单的堆栈类。

Here is a very simple stack class.

Option Explicit Dim pStack As Collection Public Function Pop() As Variant With pStack If .Count > 0 Then Pop = .Item(.Count) .Remove .Count End If End With End Function Public Function Push(newItem As Variant) As Variant With pStack .Add newItem Push = .Item(.Count) End With End Function Public Sub init() Set pStack = New Collection End Sub

测试它

Option Explicit Sub test() Dim cs As New cStack Dim i As Long Set cs = New cStack With cs .init For i = 1 To 10 Debug.Print CStr(.Push(i)) Next i For i = 1 To 10 Debug.Print CStr(.Pop) Next i End With End Sub
