EXCEL VBA:数组的升序、降序

以下的两种数组排序,仅针对数值型的数据方能排序。

升序排序的VBA数组

  Function UP(x()) As Variant()
Dim i As Integer, j As Integer, a, d()
ReDim sx(LBound(x) To UBound(x)), d(LBound(x) To UBound(x))
d = x
If LBound(x) = UBound(x) Then
sx = d
Exit Function
End If
For i = LBound(x) To UBound(x) - 1
For j = i + 1 To UBound(x)
If d(j) < d(i) Then
a = d(j): d(j) = d(i): d(i) = a
End If
Next
Next
sx = d
End Function

②VBA数组的降序排序

Function Down(x()) As Variant()
Dim i As Integer, j As Integer, a, d()
ReDim sx(LBound(x) To UBound(x)), d(LBound(x) To UBound(x))
d = x
If LBound(x) = UBound(x) Then
sx = d
Exit Function
End If
For i = LBound(x) To UBound(x) - 1
For j = i + 1 To UBound(x)
If d(j) > d(i) Then
a = d(j): d(j) = d(i): d(i) = a
End If
Next
Next
sx = d
End Function

③针对中文字符的数组排序

如果你想针对字符数组进行排序,可参考如下的代码

Sub Start() Dim arr() As Variant arr = Array("大", "都", "生", "活", "有", "你", "和", "我")

QuickSort2 arr(), 0, UBound(arr) Dim s As String For I = 1 To UBound(arr) s = s & arr(I) & " | " Next MsgBox s

End Sub Sub QuickSort2(MyArray() As Variant, L, R) Dim tp tp = 1

Dim I, J, X, Y I = L J = R X = MyArray((L + R) / 2) While (I <= J) While (StrComp(MyArray(I), X, tp) < 0 And I < R) I = I + 1 Wend While (StrComp(X, MyArray(J), tp) < 0 And J > L) J = J - 1 Wend If (I <= J) Then Y = MyArray(I) MyArray(I) = MyArray(J) MyArray(J) = Y I = I + 1 J = J - 1 End If gIterations = gIterations + 1 Wend

If (L < J) Then Call QuickSort2(MyArray(), L, J) If (I < R) Then Call QuickSort2(MyArray(), I, R)

End Sub
