在Excel列中添加唯一值到数组

标签: vba excel-vba excel

我在Excel中工作,我正在尝试遍历一列字符串并将每个唯一字符串添加到数组中。由于代码现在正在工作,因此只在数组中返回第一个唯一名称。可能有超过50个独特的字符串。你知道发生了什么吗?谢谢!

Function findPlayers()
    Dim arr1(500)
    Dim rng As Range
    Dim cell As Range
    Set rng = Range("E6:E1275")
    Dim counter As Integer
    counter = 0
    For Each cell In rng.Cells
        If isInArray(cell.Text, arr1) = False Then
            arr1(counter) = cell.Text
            counter = counter + 1
        End If
    Next cell
    findPlayers = arr1
End Function

以下是我正在使用的其他两个功能

' Comment:              Checks if a specified value is contained in the given array.
'
' Parameters:
'   value               String to be checked.
'   arr                 Array to be tested.
'                       Each item of this array is compared to source value [value] and if any of them is
'                       equal to this string, function returns True.
'                       Parameter [arr] has to be a one-dimensional array that contains only values of
'                       primitive types. If it contain any object, exception ObjectsInArrayException will
'                       be thrown.
'   isCaseSensitive     Optional parameter of Boolean type.
'                       It determines if text comparing is case sensitive.
'                       If this value is set to True, comparing is case sensitive - a letter in lowercase
'                       is treated as different than the same letter in uppercase (i.e. a ? A).
'                       If this value is set to False, it doesn't matter if a letter is in lowercase or in
'                       uppercase, since both of them are considered as the same character (i.e. a = A).
'                       Default value of this parameter is False.
'
' Returns:
'   Boolean             True - if any item of the given array [arr] is equal to the
'                               specified string [str].
'                       False - otherwise.
'
' Exceptions:
'   NotArrayException               Thrown when the given [arr] parameter is not an array.
'   ObjectsInArrayException         Thrown when the given array contains not only values of primitive
'                                   types, but also objects.
