VB如何统计二维数组中相同元素的个数?

Private Sub Command1_Click()
Dim a(), b(), blnFlag As Boolean, F%
Dim i%, j%, k%
ReDim a(1 To 6, 1 To 2)
a(1, 1) = "2"
a(1, 2) = "3a"
a(2, 1) = "11"
a(2, 2) = "5"
a(3, 1) = "34"
a(3, 2) = "11t"
a(4, 1) = "55"
a(4, 2) = "3a"
a(5, 1) = "57"
a(5, 2) = "11t"
a(6, 1) = "72"
a(6, 2) = "3a"

ReDim b(1 To 2, 1 To 1) ' B(1,1)=3a B(2,1)=3个
b(1, UBound(b, 2)) = "" ' a(LBound(a, 1), LBound(a, 2))
For i = LBound(a, 1) To UBound(a, 1)
For j = LBound(a, 2) To UBound(a, 2)
blnFlag = False
For k = LBound(b, 2) To UBound(b, 2)
If a(i, j) = b(1, k) Then blnFlag = True: Exit For
Next
If blnFlag Then
b(2, k) = b(2, k) + 1
Else
b(1, UBound(b, 2)) = a(i, j)
b(2, UBound(b, 2)) = 1
ReDim Preserve b(1 To 2, LBound(b, 2) To UBound(b, 2) + 1) '保留原值重定义数组
b(1, UBound(b, 2)) = ""
b(2, UBound(b, 2)) = 0
End If
Next
Next

For k = LBound(b, 2) To UBound(b, 2)
Print b(1, k), b(2, k)
Next
End Sub

'b 数组中二维下标的位置换了一下,以便于 保留原值重定义数组 而不出错!
