Question

真的很新，自学成才会很感激任何帮助

已将电子表格中的范围分配给数组，但它会启动数组第1行中的数据。

Dim arr As Variant
arr = Range("DATA")

有没有办法从第0行开始？提前致谢

Answer 1

范围操作很慢，最好是使用临时数组，然后在更改起始位置时复制到另一个数组。确实阵列 - ＆gt; array =非常快

Dim arr, arr2 As Variant
arr2 = Range("DATA").value2
redim arr(0 to ubound(arr2)-1, 0 to ubound(arr2,2)-1)
for i= 0 to ubound(arr2)-1
for j= 0 to  ubound(arr2,2)-1
arr(i,j)= arr2(i+1,j+1)
next
next

那么，如果你要清理范围派生的VBA数组，为什么不在你处理列范围或行范围的情况下使它们成为1维而不是错误的2维？以下是作为默认值并且也使用0作为默认值，但提供了覆盖两个默认值的方法：

Function RangeToArray(R As Range, Optional b As Long = 0, Optional collapse As Boolean = True) As Variant
    'returns a b-based array of the values in R
    'if the Range is 1-dimensional and collapse is true, the array returned is 1-dimensional
    Dim i As Long, j As Long, m As Long, n As Long, k As Long
    Dim vals As Variant, arr As Variant

    m = R.Rows.Count
    n = R.Columns.Count
    If m = 1 And n = 1 Then 'to catch an edge-case
        ReDim vals(1 To 1, 1 To 1)
        vals(1, 1) = R.Value
    Else
        vals = R.Value
    End If
    If collapse And (m = 1 Or n = 1) Then
        k = Application.WorksheetFunction.Max(m, n)
        ReDim arr(b To b + k - 1)
        For i = 1 To k
            If m = 1 Then
                arr(b + i - 1) = vals(1, i)
            Else
                arr(b + i - 1) = vals(i, 1)
            End If
        Next i
    Else
        ReDim arr(b To b + m - 1, b To b + n - 1)
        For i = 1 To m
            For j = 1 To n
                arr(b + i - 1, b + j - 1) = vals(i, j)
            Next j
        Next i
    End If
    RangeToArray = arr
End Function

它将像A = RangeToArray(Range("A1:B3"))

一样使用
