计算excel中一系列单元格中用逗号分隔的一组数字中的特定数字

Question

我有一个特殊情况，我需要计算一系列单元格或列中的特定数字，这将是这样的

1  A        
2  1,2,3
3  1,4,5
4  1,3,5,6

我需要从这个列A中单独计算“1”。对于其他所有数字，例如'2'，'3'等同样的方式。

我尝试了以下代码，但是它从单个单元格中获取了唯一的数字

Public Function Count(r As Range) As Long
Dim c As Collection
Set c = New Collection
ary = Split(r.Text, ",")
On Error Resume Next
For Each a In ary
    c.Add a, CStr(a)
    If Err.Number = 0 Then
        Count = Count + 1
    Else
        Err.Number = 0
    End If
Next a
On Error GoTo 0
End Function`

如何将其更改为范围，以及仅计算该范围内的一个数字？

Answer 1

你可以这样做：

Public Function CountNum(rng As Range, num) As Long
    Dim rv As Long, c As Range, arr, a
    num = CStr(num)
    For Each c In rng.Cells
        If Len(c.Value) > 0 Then
            arr = Split(c.Value, ",")
            For Each a In arr
                If a = num Then rv = rv + 1
            Next a
        End If
    Next c
    CountNum = rv
End Function

要打电话（例如）：

=countnum(A2:A4,1)

Count Delimited String Occurrences (UDF)

代码

'***********************************************************************
' Title:      Count Delimited String Occurrences
' Purpose:    Counts the number of occurrences of a value in delimited parts
'             of cells of a range containing not numeric values.
' Inputs:
'     CountRange:           Required. The range which cells to search.
'     CountValue:           Required. The value to search for. Variant.
'     CountDelimiter:       Optional. The delimiter by which each part of each
'         cell will be checked against CountValue. Default is ",".
'     CompareBinary0Text1:  Optional. The method how the check will be
'         performed. (Binary)  - 0 i.e. AA <> Aa <> aa. Default.
'                    (Textual) - 1 i.e. AA = Aa = aa.
'     All0OnlyOne1:         Optional. Determines if all (0 - Default) or only
