给予
Dim arr1 As Variant
Dim arr2 As Variant
Dim arr3 As Variant
arr1 = Array("A", 1, "B", 2)
arr2 = Array("C", 3, "D", 4)
问题
我可以对
arr1
和 arr2
执行什么样的操作并将结果分配给 arr3
得到类似的结果:
arr3 = ("A", "C", 1, 3, "B", "D", 2, 4)
提示(由于注释):“1)
arr1
中的元素是名称,arr2
中的元素是值,arr3
中的最终元素实际上是名称-值对,因此只要它们是配对后我不会关心它们是否按顺序排列。”
试试这个:
arr3 = Split(Join(arr1, ",") & "," & Join(arr2, ","), ",")
不幸的是,VB6 中的数组类型没有那么多令人惊叹的功能。您几乎只需迭代数组并将它们手动插入到第三个
假设两个数组的长度相同
Dim arr1() As Variant
Dim arr2() As Variant
Dim arr3() As Variant
arr1() = Array("A", 1, "B", 2)
arr2() = Array("C", 3, "D", 4)
ReDim arr3(UBound(arr1) + UBound(arr2) + 1)
Dim i As Integer
For i = 0 To UBound(arr1)
arr3(i * 2) = arr1(i)
arr3(i * 2 + 1) = arr2(i)
Next i
更新:修复了代码。对之前的错误版本感到抱歉。我花了几分钟才访问 VB6 编译器来检查它。
此函数将按照 JohnFx 的建议进行操作,并允许数组具有不同的长度
Function mergeArrays(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
Dim holdarr As Variant
Dim ub1 As Long
Dim ub2 As Long
Dim bi As Long
Dim i As Long
Dim newind As Long
ub1 = UBound(arr1) + 1
ub2 = UBound(arr2) + 1
bi = IIf(ub1 >= ub2, ub1, ub2)
ReDim holdarr(ub1 + ub2 - 1)
For i = 0 To bi
If i < ub1 Then
holdarr(newind) = arr1(i)
newind = newind + 1
End If
If i < ub2 Then
holdarr(newind) = arr2(i)
newind = newind + 1
End If
Next i
mergeArrays = holdarr
End Function
我尝试了上面提供的代码,但它给了我错误 9。 我编写了这段代码,它对于我的目的来说工作得很好。 我希望其他人也觉得它有用。
Function mergeArrays(ByRef arr1() As Variant, arr2() As Variant) As Variant
Dim returnThis() As Variant
Dim len1 As Integer, len2 As Integer, lenRe As Integer, counter As Integer
len1 = UBound(arr1)
len2 = UBound(arr2)
lenRe = len1 + len2
ReDim returnThis(1 To lenRe)
counter = 1
Do While counter <= len1 'get first array in returnThis
returnThis(counter) = arr1(counter)
counter = counter + 1
Loop
Do While counter <= lenRe 'get the second array in returnThis
returnThis(counter) = arr2(counter - len1)
counter = counter + 1
Loop
mergeArrays = returnThis
End Function
如果 Lbound 不为 0 或 1,则有效。您在开始时 Redim 一次
Function MergeArrays(ByRef arr1 As Variant, ByRef arr2 As Variant) As Variant
'Test if not isarray then exit
If Not IsArray(arr1) And Not IsArray(arr2) Then Exit Function
Dim arr As Variant
Dim a As Long, b As Long 'index Array
Dim len1 As Long, len2 As Long 'nb of item
'get len if array don't start to 0
len1 = UBound(arr1) - LBound(arr1) + 1
len2 = UBound(arr2) - LBound(arr2) + 1
b = 1 'position of start index
'dim new array
ReDim arr(b To len1 + len2)
'merge arr1
For a = LBound(arr1) To UBound(arr1)
arr(b) = arr1(a)
b = b + 1 'move index
Next a
'merge arr2
For a = LBound(arr2) To UBound(arr2)
arr(b) = arr2(a)
b = b + 1 'move index
Next a

MergeArrays = arr
End Function
我想采用 user3286479 的好主意来处理来自单列范围的数组:
Dim ws As Worksheet
Set ws = ActiveSheet
arr1 = ws.Range("A2:A10").Value2
arr2 = ws.Range("B2:B6").Value2
arr3 = Split(Join(Application.Transpose(arr1), ",") & "," & Join(Application.Transpose(arr2), ","), ",")
我喜欢的方法有点长,但比其他答案有一些优点:
这是:
Function combineArrays(ByVal toCombine As Variant, Optional ByVal newBase As Long = 1)
'Combines an array of one or more 1d arrays, objects, or values into a single 1d array
'newBase parameter indicates start position of new array (0, 1, etc.)
'Example usage:
'combineArrays(Array(Array(1,2,3),Array(4,5,6),Array(7,8))) -> Array(1,2,3,4,5,6,7,8)
'combineArrays(Array("Cat",Array(2,3,4))) -> Array("Cat",2,3,4)
'combineArrays(Array("Cat",ActiveSheet)) -> Array("Cat",ActiveSheet)
'combineArrays(Array(ThisWorkbook)) -> Array(ThisWorkbook)
'combineArrays("Cat") -> Array("Cat")
Dim tempObj As Object
Dim tempVal As Variant
If Not IsArray(toCombine) Then
If IsObject(toCombine) Then
Set tempObj = toCombine
ReDim toCombine(newBase To newBase)
Set toCombine(newBase) = tempObj
Else
tempVal = toCombine
ReDim toCombine(newBase To newBase)
toCombine(newBase) = tempVal
End If
combineArrays = toCombine
Exit Function
End If
Dim i As Long
Dim tempArr As Variant
Dim newMax As Long
newMax = 0
For i = LBound(toCombine) To UBound(toCombine)
If Not IsArray(toCombine(i)) Then
If IsObject(toCombine(i)) Then
Set tempObj = toCombine(i)
ReDim tempArr(1 To 1)
Set tempArr(1) = tempObj
toCombine(i) = tempArr
Else
tempVal = toCombine(i)
ReDim tempArr(1 To 1)
tempArr(1) = tempVal
toCombine(i) = tempArr
End If
newMax = newMax + 1
Else
newMax = newMax + (UBound(toCombine(i)) + LBound(toCombine(i)) - 1)
End If
Next
newMax = newMax + (newBase - 1)
ReDim newArr(newBase To newMax)
i = newBase
Dim j As Long
Dim k As Long
For j = LBound(toCombine) To UBound(toCombine)
For k = LBound(toCombine(j)) To UBound(toCombine(j))
If IsObject(toCombine(j)(k)) Then
Set newArr(i) = toCombine(j)(k)
Else
newArr(i) = toCombine(j)(k)
End If
i = i + 1
Next
Next
combineArrays = newArr

不幸的是,如果不逐个元素地执行,就无法使用 VBA 在数组中追加/合并/插入/删除元素,这与许多现代语言(如
Java
或 Javascript
)不同。
可以使用
split
和 join
来做到这一点,就像之前的答案所示,但这是一种缓慢的方法,而且不通用。
为了我个人的使用,我为一维数组实现了
splice
函数,类似于 Javascript 或 Java。 splice
获取一个数组,并可以选择从给定位置删除一些元素,还可以选择在该位置插入一个数组

遵循@johannes解决方案,但合并时不会丢失数据(缺少第一个元素):
Function mergeArrays(ByRef arr1() As Variant, arr2() As Variant) As Variant
Dim returnThis() As Variant
Dim len1 As Integer, len2 As Integer, lenRe As Integer, counter As Integer
len1 = UBound(arr1)
len2 = UBound(arr2)
lenRe = len1 + len2 + 1
ReDim returnThis(0 To lenRe)
counter = 0
For counter = 0 To len1 'get first array in returnThis
returnThis(counter) = arr1(counter)
Next
For counter = 0 To len2 'get the second array in returnThis
returnThis(counter + len1 + 1) = arr2(counter)
Next
mergeArrays = returnThis
End Function
要连接 Array1 和 Array2,请创建一个新数组,例如 JointArray
Dim JointArray As Variant
ReDim JointArray(UBound(Array1) + UBound(Array2) + 1) As Variant
For i = 0 To UBound(JointArray)
If i <= UBound(Array1) Then
JointArray(i) = Array1(i)
Else
JointArray(i) = Array2(i - UBound(Array1) - 1)
End If
Next
这是一个使用集合对象来组合两个一维数组并传递它们的版本 到第三个数组。不适用于多维数组。
Function joinArrays(arr1 As Variant, arr2 As Variant) As Variant
Dim arrToReturn() As Variant, myCollection As New Collection
For Each x In arr1: myCollection.Add x: Next
For Each y In arr2: myCollection.Add y: Next
ReDim arrToReturn(1 To myCollection.Count)
For i = 1 To myCollection.Count: arrToReturn(i) = myCollection.Item(i): Next
joinArrays = arrToReturn
End Function
Function marr(arr1 As Variant, arr2 As Variant) As Variant
Dim item As Variant
For Each item In arr1
i = i + 1
Next item
For Each item In arr2
i = i + 1
Next item
ReDim MergeData(0 To i)
i = 1
For Each item In arr1
MergeData(i) = item
i = i + 1
Next item
For Each item In arr2
MergeData(i) = item
i = i + 1
Next item
marr = MergeData
End Function
甚至是变量可以未初始化、空数组或对象数组(例如 Dictionary 对象)的方式。不过,一次只能处理一个维度。此外,它将 arr2 附加到 arr1,而不是合并。
Function appendArray(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
Dim holdarr As Variant
Dim ub1 As Long
Dim ub2 As Long
Dim i As Long
Dim newind As Long
' Allows for one or both variants to not be arrays
If IsEmpty(arr1) Or Not IsArray(arr1) Then
arr1 = Array()
End If
If IsEmpty(arr2) Or Not IsArray(arr2) Then
arr2 = Array()
End If
' Now we assume we DO have two ARRAYS, even if one or the other
' has no elements
ub1 = UBound(arr1)
ub2 = UBound(arr2)
If ub1 = -1 Then
appendArray = arr2
Exit Function
End If
If ub2 = -1 Then
appendArray = arr1
Exit Function
End If
' Copy the first array. We know it is not empty.
holdarr = arr1
' Grow it to the final size we need, keeping the current contents
ReDim Preserve holdarr(ub1 + ub2 + 1)
' Set the starting new index
newind = UBound(arr1) + 1
' Append the second array, allowing that it might be an array of objects
For i = 0 To ub2
If VarType(arr2(i)) = vbObject Then
Set holdarr(newind) = arr2(i)
Else
holdarr(newind) = arr2(i)
End If
newind = newind + 1
Next i
' Return the appended array
appendArray = holdarr
End Function
我真的很欣赏 Buggabil 和 Daniel McCracken 的回应。 我需要一个函数来组合多维数组,但我确信我将来会使用 Daniel 的。 我对 Buggabil 进行了一些修改,以 1) 容纳混合有变量和对象的多维数组,2) 按顺序合并两个数组而不是网格在一起(因为两个数组在 For 循环的每个步骤中组合在一起)。 有关说明,请参阅下面的“过去/现在”示例。
Function mergeArrays(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
'Appends arr2 to arr1.
'Ex: mergeArrays(Array(0,1,2,3),Array(4,5,6,7)) = Array(0,1,2,3,4,5,6,7)
'Was: mergeArrays(Array(0,1,2), Array(Array(4, Object5, Object6), _
Array(7, Object8, Object9)) = _
= Array(Array(0,1,2),4,7,Object5,Object8,Object6,Object9)
'Now: = Array(Array(0,1,2), _
Array(4, Object5, Object6), _
Array(7, Object8, Object9))
'Source: Buggabill, https://stackoverflow.com/questions/1588913/how-do-i-merge-two-arrays-in-vba
Dim holdarr As Variant, ub1 As Long, ub2 As Long, bi As Long, i As Long, newind As Long
ub1 = UBound(arr1) + 1
ub2 = UBound(arr2) + 1
bi = IIf(ub1 >= ub2, ub1, ub2)
ReDim holdarr(ub1 + ub2 - 1)
For i = 0 To bi
If i < ub1 Then
If IsObject(arr1(i)) Then
Set holdarr(newind) = arr1(i)
Else
holdarr(newind) = arr1(i)
End If
newind = newind + 1
ElseIf i < ub2 + ub1 Then
If IsObject(arr2(i - ub1)) Then
Set holdarr(newind) = arr2(i - ub1)
Else
holdarr(newind) = arr2(i - ub1)
End If
newind = newind + 1
End If

希望这对你们有些人有帮助。
使用 Split
函数扩展
ArrayToText()
方法(MS365)
如果您处理 MS/Excel 365,您可以通过传递所谓的 锯齿数组 (又称为数组的数组) 作为主要参数来简化连接和拆分 (请参阅 @user3286479 最受支持的 post ) 。这个锯齿状阵列可能包括两个甚至更多阵列,而不仅仅是arr1
和
arr2
。作为进一步的好处,我提供了决定数组是否返回合并的数组元素
连续(默认值additive=True
)或不返回(即与显式参数交织在一起
additive=False
)的选项。
Function MergeArr(jagged As Variant, _
Optional ByVal additive As Boolean = True)
'Note: returns only string elements (needs arrays of same length)
If additive Then ' all elems of 1st array, then all elems of 2nd one etc.
MergeArr = Split(Application.ArrayToText(jagged), ", ")
Else ' intertwine first elems of each array, then all second elems etc.
MergeArr = Split(Application.ArrayToText(Application.Transpose(jagged)), ", ")
End If
End Function
调用示例
Sub testMergeArr()
Dim arr1 As Variant
arr1 = Array("A", 1, "B", 2)
Dim arr2 As Variant
arr2 = Array("C", 3, "D", 4)
Dim arr3 As Variant
arr3 = MergeArr(Array(arr1, arr2))
Debug.Print "additive ~~> " & Application.ArrayToText(arr3)
arr3 = MergeArr(Array(arr1, arr2), False)
Debug.Print "alternating ~~> " & Application.ArrayToText(arr3)
End Sub
结果出现在 VB 编辑器的即时窗口中
additive ~~> A, 1, B, 2, C, 3, D, 4
alternating ~~> A, C, 1, 3, B, D, 2, 4
注意事项
上述方法的一个可能的缺点是所有元素都将作为字符串返回,因此也包括所有数值。为了避免这种情况,您可以使用以下函数或者使用FilterXML()
(顺便说一句,自2013年起可用):
Function MergeArrXML(jagged As Variant, _
Optional ByVal additive As Boolean = True)
'Note: allows to maintain not only string elements, but also numeric values (doubles)
Dim content As String
If additive Then ' all elems of 1st array, then all elems of 2nd one etc.
content = Replace(Application.ArrayToText(jagged), ", ", "</i><i>")
Else ' intertwine first elems of each array, then all second elems etc.
content = Replace(Application.ArrayToText(Application.Transpose(jagged)), ", ", "</i><i>")
End If
MergeArrXML = Application.Transpose(Application.FilterXML("<r><i>" & content & "</i></r>", "//i"))
End Function
