我现在有两列数据，第a列是编号，第x列是等级。第a列中有12个编号，其中每个编号出现的次数大于等于1，对应在第x列的等级分为A,B C三级，同一个编号对应的等级可能不同也可能相同。现在，用vba实现以下功能:选出那些出现次数大于1的编号（也就是对应等级可能不止一种或者一种等级有多行的编号），查看其在x列对应的等级；若对应的多个等级中包含A，则对于这个编号只留一个包含A的行，该编号的其余行均删除；若对应等级不包含A，则判断多个对应的等级中是否包含B，是则只留一个包含B的行，该编号的其余行均删除；若不含B,也就是只含C,则只留一个包含C的行，该编号的其余行删除
以下是GPT给出的代码:
Sub DeleteRows()
Dim i As Long
Dim lastRow As Long
Dim dict As Object
Set dict = CreateObject("Scripting.Dictionary")
' 获取最后一行的行号
lastRow = Cells(Rows.Count, "a").End(xlUp).Row
' 遍历编号列，将编号和对应的行号存入字典中
For i = 1 To lastRow
If Not dict.Exists(Cells(i, "a").Value) Then
dict.Add Cells(i, "a").Value, i
Else
dict.Item(Cells(i, "a").Value) = dict.Item(Cells(i, "a").Value) & "," & i
End If
Next i
' 遍历字典，对于出现次数大于1的编号进行处理
For Each key In dict.Keys
If UBound(Split(dict.Item(key), ",")) > 0 Then
Dim rows() As String
rows = Split(dict.Item(key), ",")
Dim foundA As Boolean, foundB As Boolean, foundC As Boolean
foundA = False: foundB = False: foundC = False
' 遍历该编号对应的所有行，查找是否包含A、B、C等级
For i = LBound(rows) To UBound(rows)
If Not foundA And Cells(rows(i), "x").Value = "A" Then
foundA = True
ElseIf Not foundB And Cells(rows(i), "x").Value = "B" Then
foundB = True
ElseIf Not foundC And Cells(rows(i), "x").Value = "C" Then
foundC = True
End If
' 如果找到了A、B、C等级，则删除该行并退出循环
If foundA Or foundB Or foundC Then
Rows(rows(i)).Delete
Exit For
End If
Next i
' 如果没有找到A、B、C等级，则删除该编号对应的所有行（除第一行）
If Not (foundA Or foundB Or foundC) Then
For i = UBound(rows) To LBound(rows) + 1 Step -1
Rows(rows(i)).Delete
Next i
End If
End If
Next key
End Sub
报错:rows as string那里声明重复了，要如何解决
【以下回答由 GPT 生成】
首先，上述代码中的dict.Item(Cells(i, "a").Value) = dict.Item(Cells(i, "a").Value)这一行是错误的，应该将其改为dict.Item(Cells(i, "a").Value) = dict.Item(Cells(i, "a").Value) & "," & i，将重复的行号用逗号连接起来。
为了实现所描述的功能，我们可以对这段代码进行优化，具体步骤如下：
dict2字典用于存储每个编号对应的等级信息。dict中。dict2中。dict2字典，筛选出出现次数大于1的编号，并根据优先级情况删除多余的行。下面是优化后的代码示例：
Sub DeleteRows()
Dim i As Long
Dim lastRow As Long
Dim dict As Object
Set dict = CreateObject("Scripting.Dictionary")
Dim dict2 As Object
Set dict2 = CreateObject("Scripting.Dictionary")
' 获取最后一行的行号
lastRow = Cells(Rows.Count, "a").End(xlUp).Row
' 遍历编号列，将编号和对应的行号存入字典中
For i = 1 To lastRow
If Not dict.Exists(Cells(i, "a").Value) Then
dict.Add Cells(i, "a").Value, i
Else
dict2.Item(Cells(i, "a").Value) = dict2.Item(Cells(i, "a").Value) & "," & i
End If
Next i
' 遍历dict2字典，删除多余的行
Dim key As Variant
Dim rowsToDelete As String
For Each key In dict2.keys
Dim levels As String
levels = dict2.Item(key)
If Len(levels) > 0 Then
Dim arrLevels() As String
arrLevels = Split(levels, ",")
Dim aFound As Boolean
Dim bFound As Boolean
Dim cFound As Boolean
aFound = False
bFound = False
cFound = False
Dim j As Long
For j = 0 To UBound(arrLevels)
Dim level As String
level = Cells(arrLevels(j), "b").Value
If level = "A" Then
aFound = True
bFound = False
cFound = False
rowsToDelete = rowsToDelete & "," & arrLevels(j)
ElseIf level = "B" Then
If Not aFound Then
aFound = False
bFound = True
cFound = False
rowsToDelete = rowsToDelete & "," & arrLevels(j)
End If
ElseIf level = "C" Then
If Not aFound And Not bFound Then
aFound = False
bFound = False
cFound = True
rowsToDelete = rowsToDelete & "," & arrLevels(j)
End If
End If
Next j
End If
Next key
' 删除多余的行
rowsToDelete = Mid(rowsToDelete, 2) ' 去掉开头的 ","
Dim arrRows() As String
arrRows = Split(rowsToDelete, ",")
Dim k As Long
For k = UBound(arrRows) To LBound(arrRows) Step -1
Rows(arrRows(k)).Delete
Next k
End Sub
请注意，上述代码假设编号列为"A"列，等级列为"B"列。如果实际情况不符，需要根据实际情况进行修改。
希望这个解决方案对您有帮助！如果还有其他问题，请随时提问。
