VBA數組的升序、降序

 　　①升序排序的VBA數組

　　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數組的降序排序

　　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針對中文字符的數組排序

　　如果你想針對字符數組進行排序，可參考如下的代碼

　　Sub Start() Dim arr() As Variant arr = Array("大", "眾", "計", "算", "機", "學", "習", "網")

　　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
