识别和计数数组Excel VBA中具有相同值的元素

Question

我想计算数组txt中"c"的数量。从1到0的转换意味着一个新的周期，这就是为什么每当这种情况发生时，我都会用"c"。在这段代码中，当我尝试计数"c"时，我得到了类型不匹配。谢谢你的帮助。

Sub CopyColumn()
Dim finalrow As Long
Dim i As Variant
ReDim arrayciclos(0)
Dim str As String
Dim ciclos As Variant
finalrow = Cells(Rows.Count, 1).End(xlUp).Row
For i = 2 To finalrow
 arrayciclos(UBound(arrayciclos)) = Range("J" & i)
 ReDim Preserve arrayciclos(UBound(arrayciclos) + 1)
Next i

For i = LBound(arrayciclos) To UBound(arrayciclos)
    txt = txt & arrayciclos(i) ' & vbCrLf
  Next i
  MsgBox txt

Do While InStr(txt, "10")
    txt = Replace(txt, "10", "c")
    Loop
MsgBox txt

ciclos = 0: i = 0
For i = 0 To finalrow
    If txt(i) = "c" Then ' i have Type Mismatch here
        ciclos = ciclos + 1
    End If
Next
MsgBox (ciclos)

End Sub

根据发布的代码，txt变量没有显式声明。此外，当您使用第二个循环将值与txt = txt & arrayciclos(I)连接在一起时，变量的隐式声明将成为一种字符串类型。您应该修改代码以包含Option Explicit语句来检查未声明的变量。此外，您应该使用Mid函数来检查最后一个循环中的"c"字符。

Option Explicit   ' <-- added to check for undeclared variables
Sub CopyColumn()
Dim finalrow As Long
Dim i As Variant
ReDim arrayciclos(0)
Dim str As String   ' <-- unused variable problaby should have been named txt in your example
Dim ciclos As Variant
finalrow = Cells(Rows.Count, 1).End(xlUp).Row
finalrow = 9
For i = 2 To finalrow
 arrayciclos(UBound(arrayciclos)) = Range("J" & i)
 ReDim Preserve arrayciclos(UBound(arrayciclos) + 1)
Next i

For i = LBound(arrayciclos) To UBound(arrayciclos)
    str = str & arrayciclos(i) ' & vbCrLf
  Next i
  MsgBox str

Do While InStr(str, "10")
    str = Replace(str, "10", "c")
    Loop
MsgBox str

ciclos = 0: i = 0
For i = 0 To finalrow
    If Mid(str, i + 1, 1) = "c" Then ' <-- changed to Mid(string, start, len)
        ciclos = ciclos + 1
    End If
Next
MsgBox (ciclos)

End Sub

我认为您使用了太多循环。如果你想循环通过数组txt来计算"c"的数量，那么你只需要做

        Dim MyArray As Variant
        dim count as integer
        'specify your range. For example
        MyArray = Range("BS27:DS50000")
        'Loop through and find all occurrences of "c"
        For i = LBound(MyArray) To UBound(MyArray)
          For j = LBound(MyArray, 2) To UBound(MyArray, 2)
             If MyArray(i, j) = "c" Then count = count + 1
          Next j
        Next i
        msgbox count

如果"c"在每个单元格中不是单个的，则将If MyArray（i，j）="c"替换为If MyArray（i，j）="c"，并将星号放在"c"的两侧，就像星号c星号一样。这将是一个字符匹配
