在數組Excel VBA中標識和計數相同值的元素

Question

我想計算數組txt中的“ c”數。 從1到0的過渡意味着一個新的周期，這就是為什么無論何時發生此情況，我都將其置於“ c”的原因。 在這段代碼中，當我嘗試計算“ c”時，我得到類型不匹配的信息。 感謝您的幫助。

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

我認為您使用的循環過多。 如果要遍歷數組txt要計算“ c”的數量，則只需執行

        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

如果每個單元格中的“ c”不是單個，則將If MyArray（i，j）=“ c”替換為If MyArray（i，j）=“ c”，然后將asterix放在asterix c asterix之類的“ c”兩側。 這將是一個字符匹配

根據您發布的代碼，沒有明確聲明txt變量。 另外，當您使用第二個循環將值與txt = txt & arrayciclos(I)串聯在一起時，variant的隱式聲明成為字符串的一種類型。 您應該修改代碼以包含Option Explicit語句，以檢查未聲明的變量。 另外，您應該使用Mid函數在最終循環中執行對“ c”字符的檢查。

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
