VBA数组排序功能？

Question 1

我正在寻找一种在VBA中对数组进行体面排序的实现。最好使用Quicksort。或者，除了冒泡或合并以外的任何其他排序算法都足够。

请注意，这是与MS Project 2003一起使用的，因此应避免使用任何Excel本机功能以及与.net相关的任何内容。

Question 2

~~在这里看看：~~
编辑： 引用源（allexperts.com）此后已经关闭，但是这里是相关的作者评论：

网上有很多算法可用于排序。功能最丰富，通常最快的是Quicksort算法。下面是它的功能。

只需通过传递带有下数组边界（通常是0）和上数组边界（即UBound(myArray)）的值（字符串或数字；没关系）的数组来简单地调用它

范例：Call QuickSort(myArray, 0, UBound(myArray))

完成后，myArray将进行排序，您可以使用它来做自己想做的事情。

Public Sub QuickSort(vArray As Variant, inLow As Long, inHi As Long)
  Dim pivot   As Variant
  Dim tmpSwap As Variant
  Dim tmpLow  As Long
  Dim tmpHi   As Long

  tmpLow = inLow
  tmpHi = inHi

  pivot = vArray((inLow + inHi) \ 2)

  While (tmpLow <= tmpHi)
     While (vArray(tmpLow) < pivot And tmpLow < inHi)
        tmpLow = tmpLow + 1
     Wend

     While (pivot < vArray(tmpHi) And tmpHi > inLow)
        tmpHi = tmpHi - 1
     Wend

     If (tmpLow <= tmpHi) Then
        tmpSwap = vArray(tmpLow)
        vArray(tmpLow) = vArray(tmpHi)
        vArray(tmpHi) = tmpSwap
        tmpLow = tmpLow + 1
        tmpHi = tmpHi - 1
     End If
  Wend

  If (inLow < tmpHi) Then QuickSort vArray, inLow, tmpHi
  If (tmpLow < inHi) Then QuickSort vArray, tmpLow, inHi
End Sub

请注意，这仅适用于一维（也称为“正常”？）阵列。（有一个工作的多维数组快速排序在这里。）

Question 3

如果有人需要，我将“快速快速排序”算法转换为VBA。

我已经对其进行了优化以在一个Int / Longs数组上运行，但是将其转换为对任意可比较元素都适用的数组应该很简单。

Private Sub QuickSort(ByRef a() As Long, ByVal l As Long, ByVal r As Long)
    Dim M As Long, i As Long, j As Long, v As Long
    M = 4

    If ((r - l) > M) Then
        i = (r + l) / 2
        If (a(l) > a(i)) Then swap a, l, i '// Tri-Median Methode!'
        If (a(l) > a(r)) Then swap a, l, r
        If (a(i) > a(r)) Then swap a, i, r

        j = r - 1
        swap a, i, j
        i = l
        v = a(j)
        Do
            Do: i = i + 1: Loop While (a(i) < v)
            Do: j = j - 1: Loop While (a(j) > v)
            If (j < i) Then Exit Do
            swap a, i, j
        Loop
        swap a, i, r - 1
        QuickSort a, l, j
        QuickSort a, i + 1, r
    End If
End Sub

Private Sub swap(ByRef a() As Long, ByVal i As Long, ByVal j As Long)
    Dim T As Long
    T = a(i)
    a(i) = a(j)
    a(j) = T
End Sub

Private Sub InsertionSort(ByRef a(), ByVal lo0 As Long, ByVal hi0 As Long)
    Dim i As Long, j As Long, v As Long

    For i = lo0 + 1 To hi0
        v = a(i)
        j = i
        Do While j > lo0
            If Not a(j - 1) > v Then Exit Do
            a(j) = a(j - 1)
            j = j - 1
        Loop
        a(j) = v
    Next i
End Sub

Public Sub sort(ByRef a() As Long)
    QuickSort a, LBound(a), UBound(a)
    InsertionSort a, LBound(a), UBound(a)
End Sub

Question 4

用德语解释，但代码是经过充分测试的就地实现：

Private Sub QuickSort(ByRef Field() As String, ByVal LB As Long, ByVal UB As Long)
    Dim P1 As Long, P2 As Long, Ref As String, TEMP As String

    P1 = LB
    P2 = UB
    Ref = Field((P1 + P2) / 2)

    Do
        Do While (Field(P1) < Ref)
            P1 = P1 + 1
        Loop

        Do While (Field(P2) > Ref)
            P2 = P2 - 1
        Loop

        If P1 <= P2 Then
            TEMP = Field(P1)
            Field(P1) = Field(P2)
            Field(P2) = TEMP

            P1 = P1 + 1
            P2 = P2 - 1
        End If
    Loop Until (P1 > P2)

    If LB < P2 Then Call QuickSort(Field, LB, P2)
    If P1 < UB Then Call QuickSort(Field, P1, UB)
End Sub

像这样调用：

Call QuickSort(MyArray, LBound(MyArray), UBound(MyArray))

Question 5

Dim arr As Object
Dim InputArray

'Creating a array list
Set arr = CreateObject("System.Collections.ArrayList")

'String
InputArray = Array("d", "c", "b", "a", "f", "e", "g")

'number
'InputArray = Array(6, 5, 3, 4, 2, 1)

' adding the elements in the array to array_list
For Each element In InputArray
    arr.Add element
Next

'sorting happens
arr.Sort

'Converting ArrayList to an array
'so now a sorted array of elements is stored in the array sorted_array.

sorted_array = arr.toarray

Question 6

自然数（字符串）快速排序

只是为了讨论这个话题。通常，如果您使用数字对字符串进行排序，则会得到以下内容：

    Text1
    Text10
    Text100
    Text11
    Text2
    Text20

但是您真的希望它能够识别数值并进行排序

    Text1
    Text2
    Text10
    Text11
    Text20
    Text100

这是怎么做的...

注意：

我很久以前从互联网上偷了快速排序，不知道现在在哪里...
我翻译了CompareNaturalNum函数，该函数最初也是从Internet用C编写的。
与其他Q排序的区别：如果BottomTemp = TopTemp，我不交换值

自然数快速排序

Public Sub QuickSortNaturalNum(strArray() As String, intBottom As Integer, intTop As Integer)
Dim strPivot As String, strTemp As String
Dim intBottomTemp As Integer, intTopTemp As Integer

    intBottomTemp = intBottom
    intTopTemp = intTop

    strPivot = strArray((intBottom + intTop) \ 2)

    Do While (intBottomTemp <= intTopTemp)
        ' < comparison of the values is a descending sort
        Do While (CompareNaturalNum(strArray(intBottomTemp), strPivot) < 0 And intBottomTemp < intTop)
            intBottomTemp = intBottomTemp + 1
        Loop
        Do While (CompareNaturalNum(strPivot, strArray(intTopTemp)) < 0 And intTopTemp > intBottom) '
            intTopTemp = intTopTemp - 1
        Loop
        If intBottomTemp < intTopTemp Then
            strTemp = strArray(intBottomTemp)
            strArray(intBottomTemp) = strArray(intTopTemp)
            strArray(intTopTemp) = strTemp
        End If
        If intBottomTemp <= intTopTemp Then
            intBottomTemp = intBottomTemp + 1
            intTopTemp = intTopTemp - 1
        End If
    Loop

    'the function calls itself until everything is in good order
    If (intBottom < intTopTemp) Then QuickSortNaturalNum strArray, intBottom, intTopTemp
    If (intBottomTemp < intTop) Then QuickSortNaturalNum strArray, intBottomTemp, intTop
End Sub

自然数比较（用于快速排序）

Function CompareNaturalNum(string1 As Variant, string2 As Variant) As Integer
'string1 is less than string2 -1
'string1 is equal to string2 0
'string1 is greater than string2 1
Dim n1 As Long, n2 As Long
Dim iPosOrig1 As Integer, iPosOrig2 As Integer
Dim iPos1 As Integer, iPos2 As Integer
Dim nOffset1 As Integer, nOffset2 As Integer

    If Not (IsNull(string1) Or IsNull(string2)) Then
        iPos1 = 1
        iPos2 = 1
        Do While iPos1 <= Len(string1)
            If iPos2 > Len(string2) Then
                CompareNaturalNum = 1
                Exit Function
            End If
            If isDigit(string1, iPos1) Then
                If Not isDigit(string2, iPos2) Then
                    CompareNaturalNum = -1
                    Exit Function
                End If
                iPosOrig1 = iPos1
                iPosOrig2 = iPos2
                Do While isDigit(string1, iPos1)
                    iPos1 = iPos1 + 1
                Loop

                Do While isDigit(string2, iPos2)
                    iPos2 = iPos2 + 1
                Loop

                nOffset1 = (iPos1 - iPosOrig1)
                nOffset2 = (iPos2 - iPosOrig2)

                n1 = Val(Mid(string1, iPosOrig1, nOffset1))
                n2 = Val(Mid(string2, iPosOrig2, nOffset2))

                If (n1 < n2) Then
                    CompareNaturalNum = -1
                    Exit Function
                ElseIf (n1 > n2) Then
                    CompareNaturalNum = 1
                    Exit Function
                End If

                ' front padded zeros (put 01 before 1)
                If (n1 = n2) Then
                    If (nOffset1 > nOffset2) Then
                        CompareNaturalNum = -1
                        Exit Function
                    ElseIf (nOffset1 < nOffset2) Then
                        CompareNaturalNum = 1
                        Exit Function
                    End If
                End If
            ElseIf isDigit(string2, iPos2) Then
                CompareNaturalNum = 1
                Exit Function
            Else
                If (Mid(string1, iPos1, 1) < Mid(string2, iPos2, 1)) Then
                    CompareNaturalNum = -1
                    Exit Function
                ElseIf (Mid(string1, iPos1, 1) > Mid(string2, iPos2, 1)) Then
                    CompareNaturalNum = 1
                    Exit Function
                End If

                iPos1 = iPos1 + 1
                iPos2 = iPos2 + 1
            End If
        Loop
        ' Everything was the same so far, check if Len(string2) > Len(String1)
        ' If so, then string1 < string2
        If Len(string2) > Len(string1) Then
            CompareNaturalNum = -1
            Exit Function
        End If
    Else
        If IsNull(string1) And Not IsNull(string2) Then
            CompareNaturalNum = -1
            Exit Function
        ElseIf IsNull(string1) And IsNull(string2) Then
            CompareNaturalNum = 0
            Exit Function
        ElseIf Not IsNull(string1) And IsNull(string2) Then
            CompareNaturalNum = 1
            Exit Function
        End If
    End If
End Function

isDigit（在CompareNaturalNum中使用）

Function isDigit(ByVal str As String, pos As Integer) As Boolean
Dim iCode As Integer
    If pos <= Len(str) Then
        iCode = Asc(Mid(str, pos, 1))
        If iCode >= 48 And iCode <= 57 Then isDigit = True
    End If
End Function

Question 7

我在StackOverflow上发布了一些代码来回答相关问题：

在VBA中对多维数组进行排序

该线程中的代码示例包括：

向量数组Quicksort；
多列数组QuickSort；
BubbleSort。

Alain优化的Quicksort非常出色：我只是做了基本的拆分和递归操作，但是上面的代码示例具有“选通”功能，可以减少重复值的冗余比较。另一方面，我为Excel编写代码，并且防御代码还有更多内容-警告，如果您的数组包含有害的“ Empty（）”变体，则您将需要它，这会破坏您的While。温和比较运算符，并将您的代码陷入无限循环。

请注意，快速排序算法-以及任何递归算法-可以填充堆栈并使Excel崩溃。如果您的数组的成员少于1024个，那么我将使用基本的BubbleSort。

Public Sub QuickSortArray（ByRef SortArray As Variant，_
                                可选的lngMin只要Long = -1，_ 
                                可选的lngMax只要Long = -1，_ 
                                可选的lngColumn只要Long = 0）
On Error Resume Next 

'将二维数组排序

'示例用法：按第3列的内容对arrData进行排序
'
'QuickSortArray arrData 、、、、

Question 8

您不想要基于Excel的解决方案，但是由于我今天遇到同样的问题，并且想使用其他Office应用程序功能进行测试，因此我在下面编写了该功能。

局限性：

Question 9

我想知道您对这个数组排序代码会怎么说。它实现起来很快，并且可以完成工作……尚未针对大型阵列进行测试。它适用于一维数组，对于多维附加值，需要构建重定位矩阵（尺寸比初始数组小一维）。

       For AR1 = LBound(eArray, 1) To UBound(eArray, 1)
            eValue = eArray(AR1)
            For AR2 = LBound(eArray, 1) To UBound(eArray, 1)
                If eArray(AR2) < eValue Then
                    eArray(AR1) = eArray(AR2)
                    eArray(AR2) = eValue
                    eValue = eArray(AR1)
                End If
            Next AR2
        Next AR1

Question 10

我认为我的代码（经过测试）更加“受过教育”，假设越简单越好。

Option Base 1

'Function to sort an array decscending
Function SORT(Rango As Range) As Variant
    Dim check As Boolean
    check = True
    If IsNull(Rango) Then
        check = False
    End If
    If check Then
        Application.Volatile
        Dim x() As Variant, n As Double, m As Double, i As Double, j As Double, k As Double
        n = Rango.Rows.Count: m = Rango.Columns.Count: k = n * m
        ReDim x(n, m)
        For i = 1 To n Step 1
            For j = 1 To m Step 1
                x(i, j) = Application.Large(Rango, k)
                k = k - 1
            Next j
        Next i
        SORT = x
    Else
        Exit Function
    End If
End Function

Question 11

这就是我在内存中排序的方式-可以轻松地扩展它以对数组进行排序。

Sub sortlist()

    Dim xarr As Variant
    Dim yarr As Variant
    Dim zarr As Variant

    xarr = Sheets("sheet").Range("sing col range")
    ReDim yarr(1 To UBound(xarr), 1 To 1)
    ReDim zarr(1 To UBound(xarr), 1 To 1)

    For n = 1 To UBound(xarr)
        zarr(n, 1) = 1
    Next n

    For n = 1 To UBound(xarr) - 1
        y = zarr(n, 1)
        For a = n + 1 To UBound(xarr)
            If xarr(n, 1) > xarr(a, 1) Then
                y = y + 1
            Else
                zarr(a, 1) = zarr(a, 1) + 1
            End If
        Next a
        yarr(y, 1) = xarr(n, 1)
    Next n

    y = zarr(UBound(xarr), 1)
    yarr(y, 1) = xarr(UBound(xarr), 1)

    yrng = "A1:A" & UBound(yarr)
    Sheets("sheet").Range(yrng) = yarr

End Sub

Question 12

堆排序实现。O（n log（n））（平均情况和最坏情况）就地是不稳定排序算法。

与：一起使用Call HeapSort(A)，其中的A是一维变体数组，与一起使用Option Base 1。

Sub SiftUp(A() As Variant, I As Long)
    Dim K As Long, P As Long, S As Variant
    K = I
    While K > 1
        P = K \ 2
        If A(K) > A(P) Then
            S = A(P): A(P) = A(K): A(K) = S
            K = P
        Else
            Exit Sub
        End If
    Wend
End Sub

Sub SiftDown(A() As Variant, I As Long)
    Dim K As Long, L As Long, S As Variant
    K = 1
    Do
        L = K + K
        If L > I Then Exit Sub
        If L + 1 <= I Then
            If A(L + 1) > A(L) Then L = L + 1
        End If
        If A(K) < A(L) Then
            S = A(K): A(K) = A(L): A(L) = S
            K = L
        Else
            Exit Sub
        End If
    Loop
End Sub

Sub HeapSort(A() As Variant)
    Dim N As Long, I As Long, S As Variant
    N = UBound(A)
    For I = 2 To N
        Call SiftUp(A, I)
    Next I
    For I = N To 2 Step -1
        S = A(I): A(I) = A(1): A(1) = S
        Call SiftDown(A, I - 1)
    Next
End Sub

Question 13

@Prasand Kumar，这是一个基于Prasand概念的完整排序例程：

Public Sub ArrayListSort(ByRef SortArray As Variant)
    '
    'Uses the sort capabilities of a System.Collections.ArrayList object to sort an array of values of any simple
    'data-type.
    '
    'AUTHOR: Peter Straton
    '
    'CREDIT: Derived from Prasand Kumar's post at: /programming/152319/vba-array-sort-function
    '
    '*************************************************************************************************************

    Static ArrayListObj As Object
    Dim i As Long
    Dim LBnd As Long
    Dim UBnd As Long

    LBnd = LBound(SortArray)
    UBnd = UBound(SortArray)

    'If necessary, create the ArrayList object, to be used to sort the specified array's values

    If ArrayListObj Is Nothing Then
        Set ArrayListObj = CreateObject("System.Collections.ArrayList")
    Else
        ArrayListObj.Clear  'Already allocated so just clear any old contents
    End If

    'Add the ArrayList elements from the array of values to be sorted. (There appears to be no way to do this
    'using a single assignment statement.)

    For i = LBnd To UBnd
        ArrayListObj.Add SortArray(i)
    Next i

    ArrayListObj.Sort   'Do the sort

    'Transfer the sorted ArrayList values back to the original array, which can be done with a single assignment
    'statement.  But the result is always zero-based so then, if necessary, adjust the resulting array to match
    'its original index base.

    SortArray = ArrayListObj.ToArray
    If LBnd <> 0 Then ReDim Preserve SortArray(LBnd To UBnd)
End Sub

Question 14

有点相关，但由于高级数据结构（字典等）在我的环境中不起作用，因此我也在寻找本机excel VBA解决方案。以下是通过VBA中的二叉树实现排序的方法：

假设数组被一一填充
删除重复项
返回一个"0|2|3|4|9"可拆分的字符串（）。

我用它来返回为任意选择范围选择的行的原始排序枚举

Private Enum LeafType: tEMPTY: tTree: tValue: End Enum
Private Left As Variant, Right As Variant, Center As Variant
Private LeftType As LeafType, RightType As LeafType, CenterType As LeafType
Public Sub Add(x As Variant)
    If CenterType = tEMPTY Then
        Center = x
        CenterType = tValue
    ElseIf x > Center Then
        If RightType = tEMPTY Then
            Right = x
            RightType = tValue
        ElseIf RightType = tTree Then
            Right.Add x
        ElseIf x <> Right Then
            curLeaf = Right
            Set Right = New TreeList
            Right.Add curLeaf
            Right.Add x
            RightType = tTree
        End If
    ElseIf x < Center Then
        If LeftType = tEMPTY Then
            Left = x
            LeftType = tValue
        ElseIf LeftType = tTree Then
            Left.Add x
        ElseIf x <> Left Then
            curLeaf = Left
            Set Left = New TreeList
            Left.Add curLeaf
            Left.Add x
            LeftType = tTree
        End If
    End If
End Sub
Public Function GetList$()
    Const sep$ = "|"
    If LeftType = tValue Then
        LeftList$ = Left & sep
    ElseIf LeftType = tTree Then
        LeftList = Left.GetList & sep
    End If
    If RightType = tValue Then
        RightList$ = sep & Right
    ElseIf RightType = tTree Then
        RightList = sep & Right.GetList
    End If
    GetList = LeftList & Center & RightList
End Function

'Sample code
Dim Tree As new TreeList
Tree.Add("0")
Tree.Add("2")
Tree.Add("2")
Tree.Add("-1")
Debug.Print Tree.GetList() 'prints "-1|0|2"
sortedList = Split(Tree.GetList(),"|")
