下面的代码目前正在删除 A 列中的所有重复事件，包括原始代码。我想修改下面的代码以删除基于 A、B、C 和 D 列的所有重复项。澄清一下，对于第 1 行和第 2 行如果列 A 匹配、B 匹配、c 匹配和 d 匹配，则两行都将被删除。有人可以提供帮助吗？我相信这里需要一个数组，但不确定如何。谢谢！ 

Dim toDel5(), p As Long
Dim RNG5 As Range, Cell5 As Long
Set RNG5 = Range("a1:a4000") 'set your range here

For Cell5 = 1 To RNG5.Cells.Count
    If Application.CountIf(RNG5, RNG5(Cell5)) > 1 Then
        ReDim Preserve toDel5(p)
        toDel5(p) = RNG5(Cell5).Address
        p = p + 1
    End If
Next

On Error GoTo NO_DUPLICATES
For p = UBound(toDel5) To LBound(toDel5) Step -1
    Range(toDel5(p)).EntireRow.Delete

Next p
On Error GoTo 0


End With 
NO_DUPLICATES:
4

这个问题似乎需要自定义算法。不确定上述是否RemoveDuplicates可以为不那么简单的情况提供可靠的答案，但在这种情况下，我更喜欢从头开始创建一些东西。就您的代码不太灵活而言，我找不到提出更正的方法，因此我创建了整个循环（我不应该做的）。请注意，此代码可以适应任何数量的分析列/行。还要记住，它依赖于目标单元格的按时删除（而不是删除整行，只能在循环之外完成）；这只是向您展示另一种替代解决方案；您可以随意更改此代码。

Dim maxRow As Long
Dim curStep, startColumn, endColumn As Integer
Dim areDuplicated As Boolean
curStep = 2 'No of rows to be considered
startColumn = 1
endColumn = 4
maxRow = 4000
For curRow = 1 To maxRow - 1
    areDuplicated = True
    For curColumn = startColumn To endColumn
        For curRow2 = curRow + 1 To curRow + curStep - 1
           If (IsEmpty(RNG5.Cells(curRow, curColumn)) Or RNG5.Cells(curRow, curColumn) <> RNG5.Cells(curRow2, curColumn)) Then
              areDuplicated = False
              Exit For
           End If

           If (Not areDuplicated) Then
              Exit For
           End If
        Next
    Next

    If (areDuplicated) Then
        For curRow3 = curRow To curRow + curStep - 1
            For curCol3 = startColumn To endColumn
                RNG5.Cells(curRow3, curCol3).Value = ""
            Next
        Next
    End If
Next

感谢 Varocarbas，这比我最终使用的代码简单一些。我使用的代码如下，以防有人想看到另一个选项。谢谢您的帮助！

Dim r As Long, c As Long, n As Long, x As Long  
Dim rData As Range 

Application.ScreenUpdating = False 
n = ActiveSheet.Cells(1, 1).CurrentRegion.Columns.Count + 1 
ActiveSheet.Cells(1, n).Value = "TEMP" 

For r = 2 To ActiveSheet.Cells(1, 1).CurrentRegion.Rows.Count 
    ActiveSheet.Cells(r, n).Value = r 
Next r 

Set rData = ActiveSheet.Cells(1, 1).CurrentRegion 

With ActiveSheet.Sort 
    .SortFields.Clear 

    For c = 1 To n
        .SortFields.Add Key:=rData.Cells(1, c).Resize(rData.Rows.Count - 1, 1) 
    Next c 

    .SetRange rData 
    .Header = xlYes 
    .MatchCase = False 
    .Orientation = xlTopToBottom 
    .SortMethod = xlPinYin 
    .Apply 
End With 

With rData 
    For r = 2 To .Rows.Count 
         x = 0 
         For c = 1 To n
            If .Cells(r, c).Value <> .Cells(r + 1, c).Value Then 
                x = x + 1 
                Exit For 
            End If 
             Next c 
         If x = 0 Then 
            .Cells(r, n).Value = True 
            .Cells(r + 1, n).Value = True 
        End If     
    Next r 
End With 

With ActiveSheet.Sort 
    .SortFields.Clear 
    .SortFields.Add Key:=rData.Cells(1, n).Resize(rData.Rows.Count - 1, 1) 
    .SetRange rData 
    .Header = xlYes 
    .MatchCase = False 
    .Orientation = xlTopToBottom 
    .SortMethod = xlPinYin 
    .Apply 
End With 

On Error Resume Next 
rData.Columns(n).SpecialCells(xlCellTypeConstants, xlLogical).EntireRow.Delete 
On Error Goto 0 

rData.Columns(n).EntireColumn.Delete 
Application.ScreenUpdating = True
