ASP自訂ArrayList類

數組是編碼中最常用不過了,但可惜的是沒有變長的數組結構,看到C#中有ArrayList,於是自己琢磨著,用ASP封裝了一個,主要是利用“Redim Preserve”重定義數組的大小,以下是My Code: 程式碼<%
'Written By Shaoyun  Site:www.devjs.com
Class ArrayList
Private m_array()
Private m_count
Private Sub Class_Initialize()
    Redim m_array(0)
    m_count=0
End Sub
Private Sub Class_Terminate()
    Redim m_array(0)
    m_count=0
End Sub
Public Property Get Count()
    Count=m_count
End Property
Public Property Get Item(index)
    Item=m_array(index)
End Property
Public Function Add(arrItem)
    Redim Preserve m_array(m_count)
    m_array(m_count)=arrItem
    m_count=m_count+1
End Function
End Class
%>

使用方法如下: 程式碼<%
dim arr : set arr=new ArrayList
arr.add "a" : arr.add "b" : arr.add "c"
Response.Write arr.count & "<br>"
for i=0 to arr.count-1
    Response.Write arr.item(i) & "<br>"
next
set arr=nothing
%>

很簡單,只有一個公用函數,兩個唯讀屬性,不過很實用!
