在数组Excel VBA中标识和计数相同值的元素

Question

我想计算数组txt中的“ c”数。 从1到0的过渡意味着一个新的周期，这就是为什么无论何时发生此情况，我都将其置于“ c”的原因。 在这段代码中，当我尝试计算“ c”时，我得到类型不匹配的信息。 感谢您的帮助。

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

我认为您使用的循环过多。 如果要遍历数组txt要计算“ c”的数量，则只需执行

        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

如果每个单元格中的“ c”不是单个，则将If MyArray（i，j）=“ c”替换为If MyArray（i，j）=“ c”，然后将asterix放在asterix c asterix之类的“ c”两侧。 这将是一个字符匹配

根据您发布的代码，没有明确声明txt变量。 另外，当您使用第二个循环将值与txt = txt & arrayciclos(I)串联在一起时，variant的隐式声明成为字符串的一种类型。 您应该修改代码以包含Option Explicit语句，以检查未声明的变量。 另外，您应该使用Mid函数在最终循环中执行对“ c”字符的检查。

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
