vba中large的用法
在VBA中,Large函数用于返回给定数值或数组中的第N个最大值。Large函数的语法如下:
Large(Array, N)
其中,Array表示要返回最大值的数值数组或范围,N表示要返回的第N个最大值的位置。
下面是一些关于Large函数的常见用法和示例:
1.返回单个数值数组中的第N个最大值:
```
Dim dataArr( As Variant
dataArr = Array(12, 35, 23, 17, 42, 10, 29)
Dim n As Integer
n=3
Dim result As Double
result = WorksheetFunction.Large(dataArr, n)
MsgBox "第" & n & "个最大值为:" & result
```
结果为:第3个最大值为:29
2.返回范围中的第N个最大值:
```
Dim dataRange As Range
Set dataRange = Range("A1:A7")
Dim n As Integer
n=2
Dim result As Double
result = WorksheetFunction.Large(dataRange, n)
MsgBox "第" & n & "个最大值为:" & result
```
结果为:第2个最大值为:35
3.返回单个数值数组中的最大值:
```
Dim dataArr( As Variant
dataArr = Array(12, 35, 23, 17, 42, 10, 29)
Dim result As Double
result = WorksheetFunction.Large(dataArr, 1)
MsgBox "最大值为:" & result
```
结果为:最大值为:42
4.返回范围中的最大值:
```
Dim dataRange As Range
Set dataRange = Range("A1:A7")
Dim result As Double
vba排序函数sort用法
result = WorksheetFunction.Large(dataRange, 1)
MsgBox "最大值为:" & result
```
结果为:最大值为:42
5. 使用Large函数和循环查多个最大值:
```
Dim dataRange As Range
Set dataRange = Range("A1:A7")
Dim numOfMaxValues As Integer
numOfMaxValues = 3
Dim maxValues( As Double
ReDim maxValues(1 To numOfMaxValues)
Dim i As Integer
For i = 1 To numOfMaxValues
maxValues(i) = WorksheetFunction.Large(dataRange, i)
MsgBox "第" & i & "个最大值为:" & maxValues(i)
Next i
```
结果为:第1个最大值为:42、第2个最大值为:35、第3个最大值为:29
6. 使用Large函数在VBA中排序数组:
```
Dim dataArr( As Variant
dataArr = Array(12, 35, 23, 17, 42, 10, 29)
Dim sortedArr( As Variant
sortedArr = SortArrayDescending(dataArr)
Dim i As Integer
For i = 1 To UBound(sortedArr)
MsgBox "第" & i & "个最大值为:" & sortedArr(i)
Next i
Function SortArrayDescending(arr( As Variant) As Variant
Dim resultArr( As Variant
resultArr = arr
Dim i As Integer, j As Integer
Dim temp As Variant
For i = LBound(resultArr) To UBound(resultArr) - 1
For j = i + 1 To UBound(resultArr)
If resultArr(i) < resultArr(j) Then
temp = resultArr(i)
resultArr(i) = resultArr(j)
resultArr(j) = temp
End If
Next j
Next i
SortArrayDescending = resultArr
End Function
```
结果为:第1个最大值为:42、第2个最大值为:35、第3个最大值为:29、第4个最大值为:23、第5个最大值为:17、第6个最大值为:12、第7个最大值为:10
希望以上的例子和解释能够帮助您理解VBA中Large函数的用法。
