Question

我已经花了好几个小时从Excel工作表中粘贴VBA数组中的一行。

代码应如下所示：

Dim wsSource As Worksheet
Set wsSource = Sheets("Data Retrieval - Source")
Dim wsDestination As Worksheet
Set wsDestination = Sheets("Data Retrieval - Destination")
Dim TableAbarSource
TableAbarSource = wsSource.Range("A3:U299729")

wsDestination.Range("A3:Z3") = ?

有什么想法吗？

非常感谢你的帮助！

添加了我需要在下面优化的原始代码（工作正常）。正如您所看到的，有近300,000个循环，因此将表声明为变量会有所帮助。

Sub DataRetrieval()

Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

'Variable definitions
    'Worksheets
Dim wsSource As Worksheet
Set wsSource = Sheets("Data Retrieval - Source")
Dim wsDestination As Worksheet
Set wsDestination = Sheets("Data Retrieval - Destination")
Dim wsDefaultList As Worksheet
Set wsDefaultList = Sheets("Default List")

    'Core ID
Dim CoreIDSource As Long 'Core ID number of the sheet Data Retrieval - Source
Dim CoreIDModel As Long 'Core ID number of the sheet Model
Dim ComparingCoreID As Variant

    'Count
Dim RowCountSource As Long 'Count the rows of the sheet Data Retrieval - Source
Dim RowCountDestination As Long 'Count the rows of the sheet Data Retrieval (destination)
RowCountDestination = 4

'Preparing sheet Data Retrieval (destination)
wsDestination.Range("A3:CC500000").Delete

With wsSource 'Copy header
    .Range(.Cells(3, 1), .Cells(3, 200)).Copy wsDestination.Cells(3, 1) 'Copy table header
End With

'Comparing Core ID of source sheet to Core ID of Model sheet
For RowCountSource = 4 To 300000

    CoreIDSource = wsSource.Cells(RowCountSource, 2)

    Set ComparingCoreID = wsDefaultList.Range("B4:B1507").Cells.Find(What:=CoreIDSource, LookIn:=xlFormulas, _
        LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
        MatchCase:=False, SearchFormat:=False) 'Definition of the Find variable 'Do not use variables for range to save time

    If Not ComparingCoreID Is Nothing Then
        With wsSource
        .Range(.Cells(RowCountSource, 1), .Cells(RowCountSource, 200)).Copy wsDestination.Cells(RowCountDestination, 1) 'Copier les données chiffrées
        End With
        RowCountDestination = RowCountDestination + 1
    End If

Next RowCountSource

Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic

End Sub

Answer 1

可能有100种不同的方法可以做到这一点：

Sub test()

Dim rSource As Range
Dim rDest As Range

Set rSource = Sheet1.Range("A1:D100")
Set rDest = Sheet2.Range("A1")
Call rSource.Resize(1).Copy(rDest)

End Sub

这样的事可能已经足够了。根据需要改变线路呼叫：

rSource.Resize(1).Copy(rDest)

类似于：

Call rSource.Resize(1).offset(10).Copy(rDest)

Answer 2

我找到了解决方案。使用循环将行数据粘贴到数组中实际上非常快。整个宏运行大约需要500万，而原始代码则超过3000万。

这里的技巧是将300,000行分成25,000行的较小块，以避免“内存不足”错误。

这是代码，也许它会帮助某人。
