这是一个递归循环,以防万一:)
实际上是两个过程,第一个对列表进行排序,第二个删除重复项

这些设置的方式你会像这样使用它们.....
QuickSort MyArray, LBound(MyArray), UBOUND(MyArray)
MyArray = RemoveDuplicatesBlanks_1DSorted(MyArray)
这些只适用于一维数组,如果你需要的话,我也有它们用于二维数组。
我已经用过很多次了,它们的速度非常快,比大多数方法都快很多,所以如果您的列表很大,那么值得使用这些方法。
----附加信息----
ExtractArrayColumn 函数在这段代码下面....这段代码是你如何使用所有这些过程的方法
Private sub RemoveDuplicate()
Dim MyRangeArray As Variant, MyArray As Variant
MyRangeArray = Range("A1:A100").Value
MyArray = ExtractArrayColumn(MyRAngeArray,1)
QuickSort MyArray, LBound(MyArray), UBOUND(MyArray)
MyArray = RemoveDuplicatesBlanks_1DSorted(MyArray)
Range("A1:A100").Value = MyArray
End Sub
Public Function ExtractArrayColumn(Array_Obj As Variant, Column_Index As Long) As Variant
Dim TArr() As Variant
Dim L1 As Long, H1 As Long
Dim i As Long
L1 = LBound(Array_Obj, 1)
H1 = UBound(Array_Obj, 1)
ReDim TArr(L1 To H1)
For i = L1 To H1
TArr(i) = Array_Obj(i, Column_Index)
Next i
ExtractArrayColumn = TArr
End Function
