使用VBA将VBA集合到Excel中

我正在尝试使用VBA代码将值复制到Excel工作表中。 我一直在尝试使用一个字典（在我的函数（8）中使用，并在第（3）和（4）节中使用）。 当我把它设置成字典的时候，所有的东西都是一个字，所以我把字典变成了一个集合。 现在问题是行d.Resize(dict.count, 1).Value = Application.Transpose(dict.count) （在第3和4节 ），因为它正在计数值并输出数值而不是名称的价值。

我想我需要改变它更像d.Resize(dict.count, 1).Value = Application.Transpose(VariantArray)但我不知道如何定义键和值，因为我没有打印一个特定的范围，但而不是特定标题下的任何东西。

如果我没有足够清楚地解释这个词，这是一个很难的想法，可以随意要求我更好地解释它，而且我会尽力引导你。

这是我的代码，非常感谢任何帮助！

Answer 1

既然你想要所有的值，不只是一个唯一的列表，更改Dictionary代码为：

 Function GetValues(ch As Range) As Object Dim dict As Object, rng As Range, c As Range, v Set dict = CreateObject("scripting.dictionary") For Each c In ch.Parent.Range(ch, ch.Parent.Cells(Rows.Count, ch.Column).End(xlUp)).Cells v = Trim(c.Value) If Len(v) > 0 And Not dict.exists(v) Then dict.Add c.Address, v End If Next c Set GetValues = dict End Function 

然后使用Items数组，而不是Keys数组：

  Set dict = GetValues(hc3.Offset(1, 0)) If dict.Count > 0 Then Set d = StartSht.Cells(Rows.Count, hc1.Column).End(xlUp).Offset(1, 0) 'add the values to the master list, column 2 d.Resize(dict.Count, 1).Value = Application.Transpose(dict.items) End If

要使用Collection对象获取唯一的项目，您需要一个密钥 。 例如：

这将得到独特的：

 Sub MAIN() Dim z As Collection, r As Range Set r = Range("A1:A4") Set z = GetNames(r) msg = z.Count & vbCrLf For i = 1 To z.Count msg = msg & z.Item(i) & vbCrLf Next i MsgBox msg End Sub 'get all unique column values starting at cell c Function GetNames(ch As Range) As Collection Dim dict As Collection, rng As Range, c As Range, v Set dict = New Collection For Each c In ch.Parent.Range(ch, ch.Parent.Cells(Rows.Count, ch.Column).End(xlUp)).Cells v = Trim(c.Value) If Len(v) > 0 Then On Error Resume Next dict.Add v, CStr(v) On Error GoTo 0 End If Next c Set GetNames = dict End Function
