            n = n + 1
             redim重新定义数组大小，preserve重新定义数组大小时，不清除以前的值
            ReDim Preserve brr(n)
            brr(n) = arr(i, 2)
        End If
    Next i
    MsgBox WorksheetFunction.Sum(brr)
End Sub

声明数组时使用变量，使用redim声明数组

Sub test()
   i = 1 + 1
    如果声明数组时，使用了变量，那么定义数组应该使用redim关键字
   ReDim arr(1 To i)
End Sub

   Dim arr(), brr(1 To 40, 1 To 3)
   arr = Range("a1").CurrentRegion
   For i = 2 To UBound(arr)
        For j = 2 To UBound(arr, 2)
            n = n + 1
            brr(n, 1) = arr(i, 1)
            brr(n, 2) = arr(1, j)
            brr(n, 3) = arr(i, j)
        Next
   Next
   Range("e2").Resize(UBound(brr), 3) = brr
End Sub

Sub test()
   arr = [a10:d10]
   arr = WorksheetFunction.Transpose(WorksheetFunction.Transpose(arr))
   For i = 1 To UBound(arr) - 1
        For j = 1 To UBound(arr) - i
            If arr(j) > arr(j + 1) Then
                temp = arr(j + 1)
                arr(j + 1) = arr(j)
                arr(j) = temp
            End If
        Next
   Next
   Range("a11").Resize(1, 4) = arr
End Sub

拆分函数split

Sub test()
   Dim str As String
   str = "zhang,li,zhao"

    MsgBox arr(i)
   Next
End Sub

   arr = Array(1, 2, 3)
   MsgBox Join(arr, "-")
End Sub

Sub test()
   arr = Array(12, 142, 43)
   brr = Filter(arr, "1")
   MsgBox Join(brr, "-")
End Sub

Sub test()
    arr = [a1].CurrentRegion
    brr = WorksheetFunction.Index(arr, 0, 1)
    brr = WorksheetFunction.Transpose(brr)
    r = WorksheetFunction.Match([e1], brr, 0)
    Range("d2:e2") = WorksheetFunction.Index(arr, r, 0)
End Sub

数组去除空值

Sub test()
    arr = WorksheetFunction.Transpose(Range("a1:a10"))
    t = Join(arr)
    t = WorksheetFunction.Trim(t)
    arr = Split(t)
    Range("b1:b6") = WorksheetFunction.Transpose(arr)
End Sub

清空数组

Sub test()
    Dim arr()
    arr = Array("zhagn", "li")
     使用erase删除指定数组中的数据
    Erase arr
    MsgBox 1
End Sub

Sub test()
    On Error Resume Next
    Dim brr()
    arr = Range("a1:a11")
    ReDim brr(1 To UBound(arr))
    For i = LBound(arr) To UBound(arr)
   判断a数组中的项，在b数组中是否存在，如果不存在就放到b数组
        n = WorksheetFunction.Match(arr(i, 1), brr, 0)
        If n = "" Then
            j = j + 1
            brr(j) = arr(i, 1)
        End If
        n = ""
    Next
    MsgBox Join(brr)
End Sub
