要将多个字符串数组合并为一个字符串数组,可以使用 VBA 中的 Join 函数。以下是示例代码:
```
Sub ConcatenateArrays()
Dim arr1() As String, arr2() As String, arr3() As String
Dim finalArr() As String, i As Integer, j As Integer, k As Integer
'初始化三个字符串数组
arr1 = Split("apple,orange,banana", ",")
arr2 = Split("cat,dog,elephant", ",")
arr3 = Split("red,green,blue", ",")
'计算最终字符串数组的长度
ReDim finalArr(UBound(arr1) + UBound(arr2) + UBound(arr3) + 3)
'将三个数组合并为一个数组
For i = 0 To UBound(arr1)
finalArr(i) = arr1(i)
Next i
k = i
For j = 0 To UBound(arr2)
finalArr(k + j) = arr2(j)
Next j
k = k + j
For j = 0 To UBound(arr3)
finalArr(k + j) = arr3(j)
Next j
'将最终数组转换为字符串
Dim finalStr As String
finalStr = Join(finalArr, ",")
'输出结果
Debug.Print finalStr
End Sub
```
在这个示例代码中,我们首先初始化了三个字符串数组 arr1、arr2 和 arr3。然后,我们计算了最终字符串数组 finalArr 的长度,并将三个数组合并为一个数组。最后,我们使用 Join 函数将最终数组转换为字符串,并输出结果。
