例如,SUM
可以执行以下操作:
=SUM(F5:F7,F6:F8,A1,E7:G7,F7,2,7)
它采用多个范围和/或单个单元格,并将它们全部添加。我的问题是如何使用VBA函数执行此操作,例如概括二进制XOR:
Function BXOR(A As Integer, B As Integer) As Integer
BXOR = CLng(A) Xor CLng(B)
End Function
当我需要=BXOR(BXOR(BXOR(w,x),y),z)
<小时/>
Function BXOR(ParamArray vars() As Variant) As Long
Dim i,j As Long
BXOR = 0
For i = 0 To UBound(vars)
If Not IsObject(vars(i)) Then
' Handle explicitly passed integer arguments, e.g. BXOR(1,[...])
BXOR = BXOR Xor CLng(vars(i))
ElseIf IsArray(vars(i).Value2) Then
' Handle 1-D ranges of cells, e.g. BXOR(A1:A3,[...])
For j = 1 To UBound(vars(i).Value2)
BXOR = BXOR Xor CLng(vars(i)(j).Value2)
Next j
Else
' Handle individual cells, e.g. BXOR(A1,[...])
BXOR = BXOR Xor CLng(vars(i).Value2)
End If
Next i
End Function

我认为您正在寻找ParamArray
您的代码应如下所示:
Function BXor(ParamArray vars() As Variant) as Long
Dim i As Long
Dim tmp As Long
For i = 0 To UBound(vars)
tmp = tmp Xor clng(vars(i))
Next
BXor = tmp
End Function

您可以使用ParamArray
传递可变数量的参数。类型必须为Variant
。
Function BXOR(ParamArray args() As Variant)
