我想找到数组中第n个最大值的索引。我可以执行以下操作,但当2个值相等时会遇到麻烦。
fltArr(0)=31
fltArr(1)=15
fltArr(2)=31
fltArr(3)=52
For i = 0 To UBound(fltArr)
If fltArr(i) = Application.WorksheetFunction.Large(fltArr, n) Then
result = i
End If
Next
n = 1 ---> 3
n = 2 ---> 2(但我希望这是0)
n = 3 ---> 2
n = 4 ---> 1

使用第二个数组快速获得您想要的内容,而无需为n
的每个值循环遍历每个元素
Sub test()
Dim fltArr(0 To 3)
Dim X
Dim n As Long
Dim lngPos As Long
fltArr(0) = 31
fltArr(1) = 15
fltArr(2) = 31
fltArr(3) = 52
X = fltArr
For n = 1 To 4
lngPos = Application.WorksheetFunction.Match(Application.Large(X, n), X, 0) - 1
Debug.Print lngPos
X(lngPos) = Application.Max(X)
Next
End Sub

编辑:
Public Sub RunLarge()
Dim n%, i%, result%, count%
Dim fltArr(3) As Integer
Dim iLarge As Integer
fltArr(0) = 31:
fltArr(1) = 15:
fltArr(2) = 31:
fltArr(3) = 52
n = 1
Debug.Print " n", "iLarge", "result"
While n <= 4
count% = n - 1
iLarge = Application.WorksheetFunction.Large(fltArr, n)
For i = 0 To UBound(fltArr)
If fltArr(i) = iLarge Then
result = i
count% = count% - 1
If count% <= 0 Then Exit For
End If
Next
Debug.Print n, iLarge, result
n = n + 1
Wend
End Sub
结果:
n iLarge result
1 52 3
2 31 0
3 31 2
4 15 1

有点&#34;脏&#34;但是看到你在Excel中......
' Create a sheet with codename wsTemp...
For i = 0 To UBound(fltArr)
wsTemp.cells(i,1) = i
wsTemp.cells(i,2) = fltArr(i)
Next
with wsTemp
.range(.cells(1,1),.cells(i,2)).sort(wsTemp.cells(1,2),xlDescending)
end with
Result = wsTemp.cells(n,1)
然后你也可以将排序扩展为&#34;按值排序,然后按索引排序&#34;如果你想控制&#34;我应该选择两个相等的2中的哪一个&#34;事...

也许这就是:
Public Sub RunLarge()
Dim fltArr() As Variant, X As Long
fltArr = Array(31, 15, 31, 52) 'Create the array
For X = 1 To 4 'Loop the number of large values you want to index
For i = LBound(fltArr) To UBound(fltArr) 'Loop the array
If fltArr(i) = Application.WorksheetFunction.Large(fltArr, 1) Then 'Find first instance of largest value
result = i
fltArr(i) = -9999 'Change the value in the array to -9999
Exit For
End If
Next
Debug.Print result
Next
End Sub
当它找到大数字的第一个实例时,它用-9999替换它,所以在下一次扫描时它将选择它的下一个实例。

这是用于查找集合中第n个最大项目的代码。您需要做的就是编写一个返回索引的函数。
Sub testColl()
Dim tempColl As Collection
Set tempColl = New Collection
tempColl.Add 57
tempColl.Add 10
tempColl.Add 15
tempColl.Add 100
tempColl.Add 8
Debug.Print largestNumber(tempColl, 2) 'prints 57
End Sub
和功能本身,我最容易想到的。
Function largestNumber(inputColl As Collection, indexMax As Long)
Dim element As Variant
Dim result As Double
result = 0
Dim i As Long
Dim previousMax As Double
For i = 1 To indexMax
For Each element In inputColl
If i > 1 And element > result And element < previousMax Then
result = element
ElseIf i = 1 And element > result Then
result = element
End If
Next
previousMax = result
result = 0
Next
largestNumber = previousMax
End Function
