在EXCEL中获取列中不重复的值的个数

Public Sub distinctCount()
'求Col列中StartRow到EndRow范围中不重复的个数
'本例是计算标题为sheet1的Excel表中的A1:A240的不重复值的个数
'修改下面四行的结尾值
Dim sheetsCaption As String: sheetsCaption = "Sheet1"
Dim Col As String: Col = "A"
Dim StartRow As Integer: StartRow = 1
Dim EndRow As Integer: EndRow = 240
'以下固定
Dim Count As Integer: Count = 0
With Sheets(sheetsCaption)

For i = StartRow To EndRow
Count = Count + 1
For j = StartRow To i - 1
If .Range(Col & i) = .Range(Col & j) Then
Count = Count - 1
Exit For
End If
Next
Next
End With
MsgBox Count
End Sub
