我正在为VBA中的数组寻找合适的排序实现。 Quicksort是首选。或者除了冒泡或合并之外的任何其他sort algorithm就足够了。
请注意,这是为了与MS Project 2003一起使用,因此应避免使用任何Excel本机函数和任何.net相关的内容。

看看here:
修改:引用的来源(allexperts.com)已关闭,但以下是相关的author评论:
Web上有许多可用于排序的算法。最通用,通常最快的是Quicksort algorithm。以下是它的功能。
只需通过传递一个值数组(字符串或数字;无关紧要)并使用下部数组边界(通常为
0
)和上部数组来调用它边界(即UBound(myArray)
。)示例 :
Call QuickSort(myArray, 0, UBound(myArray))
完成后,
myArray
将被排序,你可以用它做你想做的事 (来源:archive.org)
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(又名“普通”?)数组。 (有一个可用的多维数组QuickSort here。)

如果其他人想要的话,我将'快速快速排序'算法转换为VBA。
我已将其优化为在Int / Longs数组上运行,但将其转换为适用于任意可比元素的数组应该很简单。
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)

Explanation,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))

Sorting a multidimensionnal array in VBA
该主题中的代码示例包括:
Alain的优化Quicksort非常闪亮:我只是做了一个基本的拆分和递归,但上面的代码示例有一个'门控'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,并且在防御性编码方面还有一些 - 请注意,如果你的数组包含有害的'Empty()'变体,你将需要它,这会破坏你的.. 。使用比较运算符并将代码陷入无限循环。
请注意,quicksort algorthms - 以及任何递归算法 - 都可以填充堆栈并使Excel崩溃。如果你的阵列少于1024个成员,我会使用一个基本的BubbleSort。

自然数(字符串)快速排序
只是为了谈论这个主题。 通常情况下,如果您使用数字对字符串进行排序,您将得到如下内容:
Text1

Text20
但你确实希望它识别数值并按照

Debug.Print Tree.GetList() 'prints "-1|0|2"
sortedList = Split(Tree.GetList(),"|")
答案 13 :(得分:0)
参考 VBA ArrayList - System.Collections.ArrayList
适用于对单元格内的分隔项进行排序,行或列中的不同单元格(受转置限制 - 最多 65536 行;除此之外,此函数可以在子程序中使用以填充具有排序值的范围)。
此功能不需要遍历项目。假设有 100 个项目,那么将每个值与其他项目进行比较的其他过程需要 100 x 100 = 10000 次循环。这将需要最多 100 x 2 = 200 个数字和文本项目循环和 300 个日期循环。因此,VBA ArrayList 我们对大量项目进行排序很有用。
