如何利用EXCEL VBA将一列数据中不重复的数据读取到数组中？

Answer 1

利用字典去重,下面是示例代码,去除第一列的重复项Sub Test() '利用字典去重,字典的特性是key值不能重复

Dim Dic, Arr

Dim i As Integer, r As Integer

Dim Str As String

r = Sheet1.Range("A65536").End(xlUp).Row

If r = 1 Then Exit Sub '如果第一列没有数据那么退出程序

Set Dic = CreateObject("scripting.dictionary") '创建字典对象

For i = 1 To r '将第一列数据添加到字典的key值中

Dic(CStr(Cells(i, 1))) = ""

Next

Arr = Dic.keys '返回字典key的数组

Set Dic = Nothing '销毁对象

Str = Join(Arr, ",") '将数组中的内容显示为一字符串

MsgBox Str

End Sub
