大神看看什么情况

1. Sub test()
   
2. Dim t
   
3. Dim i As Long
   
4. Dim arr
   
5. t = Timer
   
6. Dim d As Object
   
7. Set d = CreateObject("scripting.dictionary")
   
8. For i = 1 To 1000000
   
9.     If Abs(i Mod 6 - 3) = 2 Then
   
10.         j = j + 1
    
11.         Range("b" & j) = i
    
12.     End If
    
13. Next
    
14. t = Timer - t
    
15. MsgBox t
    
16. End Sub
    
17. Sub test1()
    
18. t = Timer
    
19. Dim i As Long
    
20. Dim arr
    
21. Dim d As Object
    
22. Set d = CreateObject("scripting.dictionary")
    
23. For i = 1 To 1000000
    
24.     d.Add i & IIf(Abs(i Mod 6 - 3) = 2, "@", ""), ""
    
25. Next
    
26. arr = Application.WorksheetFunction.Transpose(Filter(d.keys, "@"))
    
27. [a1].Resize(UBound(arr), 1) = arr
    
28. [a:a].Replace "@", ""
    
29. Debug.Print 4 Mod 6
    
30. t = Timer - t
    
31. MsgBox t
    
32. End Sub
    
33. 下面这个摘自蓝桥玄霜的字典用法集锦
    
34. 怎么到100万就报错了，是数组放不下了么
    
35. arr = Application.WorksheetFunction.Transpose(Filter(d.keys, "@"))
    
36. 显示类型不匹配

'问题应该出在Filter上，因为Transpose当数据多余16^4时会出现数据丢失而不是出错，这行出错也不会是字典的问题

'字典一般用于去重或定位，这里用不着。不用字典效率会高的多，，，

Option Explicit

Const NUM As Long = 10 ^ 6

Sub test1()
  Dim i As Long, m As Long, arr(1 To NUM, 1 To 1) As Long, t As Single
  t = Timer
  For i = 1 To NUM
    If Abs(i Mod 6 - 3) = 2 Then m = m + 1: arr(m, 1) = i
  Next
  Debug.Print Timer - t
  With [b:b]
    .ClearContents
    If m > 0 Then .Resize(m) = arr
  End With
  Debug.Print Timer - t
End Sub
