ASP教程:ASP关于数组的应用技巧

数组的定义

Dim MyArray
MyArray = Array(1,5,123,12,98)

可扩展数组

Dim MyArray()
for i = 0 to 10
ReDim Preserve MyArray(i)
MyArray(i)=i
next

将一个字符串分割并返回分割结果的数组

Dim MyArray
MyArray = Split(tempcnt,chr(13)&chr(10))
For I = Lbound(MyArray) to Ubound(MyArray)
Response.Write MyArray(I) & "<br>"
Next

数组排序函数

function Sort(ary)
KeepChecking = TRUE
Do Until KeepChecking = FALSE
KeepChecking = FALSE
For I = 0 to UBound(ary)
If I = UBound(ary) Then Exit For
If ary(I) > ary(I+1) Then
FirstValue = ary(I)
SecondValue = ary(I+1)
ary(I) = SecondValue
ary(I+1) = FirstValue
KeepChecking = TRUE
End If
Next
Loop
Sort = ary
End function

数组排序函数应用例子

Dim MyArray
MyArray = Array(1,5,123,12,98)
MyArray = Sort(MyArray)
For I = Lbound(MyArray) to Ubound(MyArray)
Response.Write MyArray(I) & "<br>"
Next

在Application和Session中使用数组

Application.Lock
Application("StoredArray") = MyArray
Application.Unlock

LocalArray = Application("StoredArray")

覆盖Application中的数组

Application.Lock
Application("StoredArray") = LocalArray
Application.Unlock

Session使用方法与Application相同

从数据库中把数据导入数组中
Dim MyArray
取出全部记录
MyArray = RS.GetRows
取出前10项记录

MyArray = RS.GetRows(10)

For row = 0 To UBound(MyArray, 2)
For col = 0 To UBound(MyArray, 1)
Response.Write (col, row) & "<br>"
Next
Next

dim ID,ArrayID,Myarray,M
ID="55,48,78,10,90"
ArrayID=split(ID,",")
Myarray=Sort(ArrayID)
'排序测试
For M=0 To Ubound(Myarray)
Response.Write Myarray(M) & "<br>" & vbCRLF
Next

'当然也可以用下面的，
Dim Myarray
Myarray=Array(12,10,25,78,45)
Myarray=Sort(ArrayID)
'排序测试
For M=0 To Ubound(Myarray)
Response.Write Myarray(M) & "<br>" & vbCRLF
Next
