如何在Excel中生成长度为5的数字{0,1,2,3,4,5,6,7,8,9}的所有可能组合。我知道有10 ^ 5种可能的重复组合。 谢谢

稍微修改了elene的代码。
Sub AllCombinations()
Dim nums(): nums = Array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
Dim arValues(99999, 4)
Dim n1 As Integer, n2 As Integer, n3 As Integer, n4 As Integer, n5 As Integer, x As Long
For n1 = 0 To UBound(nums)
For n2 = 0 To UBound(nums)
For n3 = 0 To UBound(nums)
For n4 = 0 To UBound(nums)
For n5 = 0 To UBound(nums)
arValues(x, 0) = nums(n1)
arValues(x, 1) = nums(n2)
arValues(x, 2) = nums(n3)
arValues(x, 3) = nums(n4)
arValues(x, 4) = nums(n5)
x = x + 1
Next
Next
Next
Next
Next
Range("A1").Resize(100000, 5).Value2 = arValues
End Sub

这可能会更快一点:
Sub combinations()
Dim wb As Workbook, i As Integer, strFileName As String
'Create Temp Workbook for data source
Set wb = Workbooks.Add
With wb.ActiveSheet
.Range("A1").Value = "Integer"
For i = 0 To 9
.Range("A" & i + 2).Value = i
Next i
End With
strFileName = "C:\Temp\Temp.xlsx"
wb.SaveAs strFileName
wb.Close False
'Create List using Temp Workbook as source(s)
With ActiveSheet.ListObjects.Add(SourceType:=0, Source:=Array(Array("ODBC;DBQ=" & strFileName & ";DefaultDir=C:\temp;Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};DriverId=1046;FIL=exce"), Array("l 12.0;MaxBufferSize=2048;MaxScanRows=8;PageTimeout=5;ReadOnly=1;SafeTransactions=0;Threads=3;UID=admin;UserCommitSync=Yes;")), Destination:=Range("$A$1")).QueryTable
.CommandText = Array( _
"SELECT `Sheet1$`.Integer, `Sheet1$_1`.Integer, `Sheet1$_2`.Integer, `Sheet1$_3`.Integer, `Sheet1$_4`.Integer" & Chr(13) & "" & Chr(10) & "FROM `" & strFileName & "`.`Sheet1$` `Sheet1$`, `" & strFileName & "`.`Sheet1$` `Sheet1$_1`, `", strFileName & "`.`Sheet1$` `Sheet1$_2`, `" & strFileName & "`.`Sheet1$` `Sheet1$_3`, `" & strFileName & "`.`Sheet1$` `Sheet1$_4`")
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.BackgroundQuery = True
.RefreshStyle = xlInsertDeleteCells
.SavePassword = False
.SaveData = False
.AdjustColumnWidth = True
.RefreshPeriod = 0
.PreserveColumnInfo = True
.ListObject.DisplayName = "Table_Query_from_Temp"
.Refresh BackgroundQuery:=False
End With
'Convert back to range
ActiveSheet.ListObjects("Table_Query_from_Temp").Unlist
'Delete top row
Rows("1:1").Delete
'Delete Temp file
Kill strFileName
End Sub
比原来快得多。阵列方法可能不是很多。这至少是一种不同的技术......
